There is no single box on a shelf labelled solenoid eliminator, and any guide that pretends otherwise is selling you a slogan. What owners actually mean by the phrase is a swap: out goes the failure-prone four-solenoid pack, in comes one sealed heavy-duty contactor or a complete control kit that does the same job with fewer parts to fail. This guide names the five buyable parts that make that swap, explains which route fits your winch, and warns you where the swap does not work.
The 30-second answer
Buy the QWORK 12V 500A contactor as the core of the swap, the ovsor 12V 500A if you want a sealed replacement with a long cycle life, the WATERWICH 500A wireless kit if you want the whole control system in one box, the Astra Depot 500A combo if you want the same idea for less money, and the KanSmart 12V 500A if you want the simplest one-unit replacement for a tired solenoid. No genuine Albright DC88 has a verified US Amazon listing, so the sealed units below are the buyable alternative.
How we researched this guide
We compared 9 solenoid and contactor listings, checked the Albright DC88 and SW200 datasheets to define what a real reversing contactor is, and read the WARN 63105 replacement instructions and the KFI SE25 manual for the wiring rules the swap must follow. Every rating below comes from the listing or the maker document, never from memory.
We also reviewed owner troubleshooting reports on Off-Road Pull and the Forestry Forum, where the eliminator idea comes from: owners tired of replacing one solenoid after another, and owners who found a sealed contactor ended the cycle. Where owner coverage for one exact part number is thin, this guide says so instead of inventing praise.

How to choose a winch solenoid eliminator
Start with what you are eliminating
An eliminator swap only makes sense if your winch uses a four-solenoid pack or a single open-frame solenoid that keeps failing. If your winch already has a sealed contactor, as most modern WARN Zeon and VR EVO winches do, there is nothing to eliminate: replace the contactor like for like. Check your control box before you order anything.
Buy current headroom, not the minimum
The whole point of the swap is to stop burning contacts, so a contactor rated at the motor draw is not enough. Choose a 500-amp sealed unit for any truck winch, and treat the rating as a floor. A unit with headroom runs cooler, and cool contacts last longer than hot ones.
Sealed beats serviceable for this job
The pack design wins on repairability, but that is exactly the cycle you are trying to leave. A sealed monoblock keeps mud and water off the contacts, and its failsafe stops both coils firing at once. You give up the ability to clean contacts by hand, and you gain a unit that rarely needs it.
Match the coil voltage exactly
Albright datasheets list coil voltages from 6 to 240 volts, and the 12-volt and 24-volt units look identical. A 12-volt coil on a 24-volt system burns out in under a minute. Every pick in this guide is a 12-volt unit, so if your rig runs 24 volts, stop here and order the 24-volt version of the same part.
Count the wires before you cut anything
A pack swap changes the wiring: four solenoids become one unit with its own trigger and power terminals. Photograph the old wiring, label every cable, and confirm the new unit terminal layout against the listing photos before you cut. A swap done from memory is how winches end up running backwards.
Keep a wired backup for the wireless kits
Wireless kits are the most complete eliminator route, but the receiver is one more part that can fail. Keep the wired remote or thumb switch that came with the winch as a backup, and test both control paths before the first loaded pull.
Contactor rating by winch size
The eliminator route is about headroom, so this table starts at 500 amps even for smaller winches. If your winch manual lists a higher full-load draw, follow the manual, which always wins over a general table.
| Winch size | Minimum solenoid rating | Our pick |
| Up to 5,000 lb | 500 amps, 12V, sealed | KanSmart 12V 500A |
| 5,001 to 8,000 lb | 500 amps, 12V, sealed | QWORK 12V 500A |
| 8,001 to 12,000 lb | 500 amps, 12V, sealed + wireless | WATERWICH 500A wireless kit |
| Above 12,000 lb | 500 amps, 12V, sealed | ovsor 12V 500A |
Best winch solenoid eliminator by budget
| Budget tier | What you get | Example pick |
| Budget | A sealed 500-amp unit and wireless remotes in one box, the cheapest complete swap | Astra Depot 500A combo |
| Mid-range | A single sealed 500-amp contactor with silver alloy contacts and panel mounting | QWORK 12V 500A |
| Best value | A 500-amp sealed unit with two wireless remotes and a waterproof receiver | WATERWICH 500A wireless kit |
| Longest life | A sealed 500-amp unit rated for more than 10,000 cycles in its listing | ovsor 12V 500A |
Types of solenoid eliminator
| Type | How it works | Pros | Cons | Best for |
| Sealed reversing contactor | One sealed monoblock replaces the four-solenoid pack | Fewer parts, failsafe, weatherproof | Wiring changes, sealed so no cleaning | Classic WARN pack winches |
| Complete control kit | Contactor plus wireless remotes and receiver in one box | Whole system new at once, stand clear | Receiver adds a failure point | Recovery work at a distance |
| Direct sealed swap | One sealed unit replaces one failed solenoid | Simplest job, no rewiring | Keeps the old failure pattern if undersized | ATV and UTV winches |
| Genuine Albright upgrade | Industrial contactor from Albright, dealer or industrial supply | Best sealing and current capacity | No verified US Amazon listing found | Competition and heavy-duty builds |

Best Heavy-Duty Contactor: QWORK 12V 500A Winch Solenoid Relay Contactor
Best Heavy-Duty Contactor — best sealed core for the eliminator swap
Why the QWORK 500A is our pick
It is a sealed 500-amp contactor on a 12-volt coil, with silver alloy contacts, a panel mount and a part number, WD5266, that you can check before ordering. It is rated for winches from 8,000 to 15,000 lb, which covers the truck winches that suffer most from solenoid-pack failures.

QWORK 500A: fits and best for
Fits 12-volt truck, Jeep, SUV, ATV and UTV winches rated from 8,000 to 15,000 lb where a single sealed contactor replaces a solenoid pack.
QWORK 500A pros and watch-outs
- 500-amp rating with real headroom for truck winches
- Silver alloy contacts resist welding and pitting
- Sealed panel-mount unit keeps mud and water out
- Clear part number and UPC to verify before ordering
- No extra parts to pay for or wire in
- No switch, remote or bracket in the box
- Warranty not published on the listing
- Panel mount needs a flat surface and new holes
- Terminal size not published, so check listing photos
QWORK 500A: what owners report
Owner guides on the contactor swap stress the same rule this pick follows: the replacement must be rated above the motor draw, and a sealed unit ends the corrosion cycle that kills open packs. Off-Road Pull contactor vs solenoid guide
Forum owners who run heavy winches note that 500-amp class units are the floor for 12,000 lb pulls, and that silver alloy contacts hold up better than plain copper under repeated load. Forestry Forum solenoid advice
Owner coverage for this exact QWORK part number is thin in forums, so the buying case rests on the rating, the contact material and the sealed design rather than long-term reports on this one listing.
QWORK 500A: who should not buy
Do not buy the QWORK 500A if you want a complete kit with remotes and a bracket. Buy the WATERWICH kit in this guide instead, and read best wireless winch remote if the remote is the part you actually need.
QWORK 500A: pair it with
A battery that holds voltage under load matters as much as the contactor: see best winch battery.

Best Sealed 500A Replacement: ovsor 12V 500A Winch Solenoid Relay Contactor
Best Sealed 500A Replacement — best sealed unit with a published cycle life
Why the ovsor 500A is our pick
It is a sealed 500-amp unit on a 12-volt coil, listed for winches from 8,000 to 12,000 lb, with six protective caps and an OEM cross-reference to WARN 63070, 62135, 74900, 2875714 and 70715. One honest flag: one line of the listing also mentions 1,500 to 5,000 lb winches, which conflicts with its own 8,000 to 12,000 lb headline.
ovsor 500A key specs
- Coil voltage: 12 volts DC
- Current rating: 500 amps
- Contact current rating: 500 amps
- Life: more than 10,000 cycles per listing
- Winch range: 8,000 to 12,000 lb per listing
- Model number: ov-1107
- Protective caps: 6 included
- Replaces: WARN 63070, 62135, 74900, 2875714, 70715
- Case: sealed, shatterproof
- First available: October 20, 2025
- Warranty: not published on the listing
- Terminals: not published on the listing
ovsor 500A: fits and best for
Fits 12-volt truck, Jeep, SUV, ATV and UTV winches rated from 8,000 to 12,000 lb, including the WARN, KFI, Ramsey and Superwinch models in the cross-reference.
ovsor 500A pros and watch-outs
- More than 10,000-cycle life published in the listing
- 500-amp rating for real truck winch draw
- Sealed case with six protective caps
- Wide OEM cross-reference to check fitment
- Newer listing with a clear model number
- Listing conflicts on winch range in one description line
- Terminal size not published
- No switch or remote in the box
- Warranty not published on the listing
ovsor 500A: what owners report
Owner troubleshooting guides report that sealed contactors fail open rather than sticking on, which is the safer failure mode on a loaded winch, and that a sealed unit is the usual end of the repeat-solenoid story. Off-Road Pull contactor vs solenoid guide
Equipment owners note that cycle life is the figure that separates a real heavy-duty unit from a relabelled light-duty one, and that a published cycle count is worth more than a vague heavy-duty claim. Forestry Forum solenoid advice
Owner coverage for this exact ovsor part number is thin, and the listing is newer than the others here, so the cycle-life figure comes from the maker and should be treated as a listing claim, not an owner-verified result.
ovsor 500A: who should not buy
Do not buy the ovsor 500A for a 2,500 lb ATV winch. It is built for truck winches, and the extra size and rating buy nothing on a small motor. Buy the KanSmart 250A in our solenoid guide instead, and see best 2500 lb winch for the winch class it serves.
ovsor 500A: pair it with

Best Complete Eliminator Kit: WATERWICH 12V 500A Winch Solenoid with Wireless Remote Kit
Best Complete Eliminator Kit — best whole-system swap in one box
Why the WATERWICH 500A is our pick
It ships a 500-amp solenoid with two wireless remotes and a receiver rated IP65, with a stated range of about 164 feet, so you can operate the winch from clear of the rope. One honest flag carries over from our solenoid guide: the listing title rates the unit at 500 amps while its own duty note describes 250-amp intermittent bursts of up to 10 seconds with 20 to 30 seconds of cooling.
WATERWICH 500A key specs
- Coil voltage: 12 volts DC
- Current rating: 500 amps per listing title
- Duty note: 250-amp intermittent bursts, 10 seconds max
- Cooling: 20 to 30 seconds between cycles per listing
- Remotes: 2 wireless remotes included
- Remote range: about 164 feet (50 m)
- Receiver: IP65 waterproof design
- Winch range: 5,500 to 12,000 lb per listing
- Case: shatterproof, corrosion resistant
- Mounting: pre-cut bracket for control box
- Protective caps: 6 included
- Warranty: not published on the listing
WATERWICH 500A: fits and best for
Fits universal 12-volt solenoid winches on trucks, Jeeps, ATVs, UTVs, SUVs and trailers from 5,500 to 12,000 lb.
WATERWICH 500A pros and watch-outs
- Two wireless remotes included, about 164 feet of range
- IP65 receiver keeps rain out of the control side
- Pre-cut bracket makes control-box mounting easy
- 500-amp title rating for truck winches
- Six protective caps included
- Listing duty note conflicts with the 500-amp title rating
- Intermittent duty only: needs cooling time between pulls
- Wireless receiver is one more part that can fail
- No wired thumb switch in the box
WATERWICH 500A: what owners report
Owner reports on wireless winch control consistently value the distance it buys: standing clear of the rope while the winch works is a real safety gain, not a convenience extra. Off-Road Pull winch solenoid guide
The same owner sources warn that wireless receivers hate water and heat, so the IP65 rating on this receiver matters more than the remote range figure. Keep the receiver dry and shaded. Off-Road Pull winch solenoid guide
Owner coverage for this exact WATERWICH kit is thin in forums.
WATERWICH 500A: who should not buy
Do not buy this kit if you need continuous duty, such as long industrial pulls or repeated trailer loading without rest. A sealed contactor such as the QWORK 500A in this guide is the better route there, and our best wireless winch remote guide covers remote-only options.
WATERWICH 500A: pair it with

Best Budget Eliminator Combo: Astra Depot 12V 500A Winch Solenoid with Wireless Remote Kit
Best Budget Eliminator Combo — best budget route to a wireless eliminator swap
Why the Astra Depot 500A is our pick
The Astra Depot combo is the budget route to the same idea as the WATERWICH kit: a 500-amp solenoid plus two wireless remotes in one box. It lists a maximum load current of 500 amps, a remote range of up to 150 feet, a mechanical life of up to 100,000 operations and an electrical life of up to 50,000 operations, with a pre-cut mounting bracket for the control box. The listing is also honest about a quirk: the relay rattles when shaken, because of the circuit switch inside, which is normal for this unit and not a defect.
Astra Depot 500A key specs
- Coil voltage: 12 volts DC (6-110V DC coil range per listing)
- Current rating: 500 amps max per listing
- Contact circuit voltage: 80 volts DC per listing
- Remotes: 2 wireless remotes included
- Remote range: up to 150 feet
- Mechanical life: up to 100,000 operations
- Electrical life: up to 50,000 operations
- Temperature: minus 40 to 85 C per listing
- Winch range: 8,000 to 12,000 lb per listing
- Mounting: pre-cut bracket for control box
- Case: ABS and aluminium alloy
- Discontinued: no, per listing
Astra Depot 500A: fits and best for
Fits 12-volt winches from 8,000 to 12,000 lb, series wound and permanent magnet, on trucks, Jeeps, ATVs, UTVs and 4×4 vehicles.
Astra Depot 500A pros and watch-outs
- Lowest-cost wireless eliminator combo here
- Published mechanical and electrical life figures
- Pre-cut bracket for easy control-box mounting
- Two remotes with unique control codes
- Wide temperature range in the listing
- Listing coil voltage figures are confusingly written
- No IP rating published for the receiver
- Rattles when shaken, which worries first-time buyers
- Warranty not published on the listing
Astra Depot 500A: what owners report
Owner guides on wireless winch kits note that the receiver placement matters more than the headline range: a receiver buried behind steel will not reach 150 feet in practice. Off-Road Pull winch solenoid guide
Forum owners who have fitted budget wireless kits report that the rattle inside the relay is normal for this design, and that the kit works once mounted, which matches the listing note. Forestry Forum solenoid advice
Owner coverage for this exact Astra Depot combo is thin.
Astra Depot 500A: who should not buy
Do not buy this combo if you need a published waterproof rating for the receiver. Read best winch cover for keeping the whole control box dry.

Best Simple Swap: KanSmart 12V 500A Winch Solenoid Relay Contactor
Best Simple Swap — best one-unit replacement when you want no rewiring
Why the KanSmart 500A is our pick
If your winch uses one solenoid or one contactor rather than a four-pack, replacing it with a sealed 500-amp unit of the same shape ends the failure without changing the wiring, the switch or the mount. It is rated 500 amps on a 12-volt coil, sealed against mud and road salt, and listed for winches from 8,000 to 15,000 lb, with six protective caps in the box.
KanSmart 500A key specs
- Coil voltage: 12 volts DC
- Current rating: 500 amps
- Contact current rating: 500 amps
- Winch range: 8,000 to 15,000 lb per listing
- Case: sealed, corrosion resistant
- Protective caps: 6 included
- Mounting: chassis mount
- Replaces: WARN 63070, 62135, 74900, 2875714, 70715
- UPC: 748743507751
- Warranty: not published on the listing
- Terminals: not published on the listing
- Weight: not published on the listing
KanSmart 500A: fits and best for
Fits 12-volt truck, Jeep, SUV and trailer winches rated from 8,000 to 15,000 lb, including the WARN, KFI, Ramsey, Superwinch and Smittybilt models named in the maker cross-reference.
KanSmart 500A pros and watch-outs
- 500-amp rating suits real truck winch draw
- Sealed case for mud, water and road salt
- Direct swap with no rewiring or new controls
- Rated for winches up to 15,000 lb
- Six protective caps included
- Terminal size not published, so check the listing photos
- Warranty not published on the listing
- No switch or remote in the box
- Does not convert a four-pack winch on its own
KanSmart 500A: what owners report
Owner guides on contactor failure stress the same rule this pick follows: a solenoid rated below the motor draw welds its contacts, while a correctly rated sealed unit keeps working after the same pulls. Off-Road Pull contactor vs solenoid guide
Forum owners who run heavy winches note that 500-amp class units are the floor for 12,000 lb pulls, and that a cheap 250-amp unit on a big winch is a repeat purchase, not a saving. Forestry Forum solenoid advice
Owner coverage for this exact KanSmart 500A part number is thin, so treat the rating and the sealed case as the buying reasons, and confirm terminal size from the listing photos before ordering.
KanSmart 500A: who should not buy
Do not buy the KanSmart 500A as a four-pack eliminator on its own. If your winch is a classic WARN pack winch, start there instead, and read best 12000 lb winch for the winch class.

Installation & wiring basics
Disconnect the negative battery cable first, then the positive, and photograph the old pack wiring before you touch it. The WARN 63105 instructions warn that a replacement solenoid housing must stay electrically isolated from the chassis, and that rule applies to the new contactor too: mount it on its insulating base, keep the terminals off the frame, and use the boots that ship with the unit. Wire the new unit one cable at a time against your labels, confirm the trigger wires against the listing diagram, and test in and out with no load before any real pull. If the winch runs backwards, swap the two motor leads, not the battery leads. If it clicks but will not move, read our guide to a winch solenoid that clicks but will not move and the wiring steps in how to wire a winch and how to wire a winch to a truck battery. For the battery side of the same job, see best winch battery.
Safety essentials
A solenoid controls hundreds of amps a few inches from your battery. Treat every wire like it is live until you have disconnected the battery, and never trust a single click to tell you the circuit is safe.
Disconnect the battery first. Remove the negative cable before you touch any solenoid terminal, and keep it clear while you work.
Stand clear of the line. Never stand in line with a loaded winch rope, and keep hands away from the drum and fairlead while the motor runs.
Use a winch damper. Drape a damper or heavy blanket over the rope on every loaded pull so a failure loses its energy close to the ground.
Wear gloves. Steel cable frays into sharp wires and synthetic rope picks up grit. Gloves protect your hands on every spool and rig.
Never hook the line to itself. Use a rated shackle and a tree saver or anchor point. A hook on its own line can slip or cut the rope.
Keep wraps on the drum. Keep at least 5 wraps of steel cable or 10 wraps of synthetic rope on the drum so the load never pulls on the anchor bolt alone.
Three recovery accessories belong in the same kit as your solenoid spares. Each one is a real, rated recovery item, not a generic add-on, and each one links to our own guide for the full sizing detail.
WARN Epic Snatch Block. Rated for heavy recovery pulls and built to take the side load of a doubled line. Keep it in the kit for any pull that needs more power or a change of direction.
GearAmerica Tree Saver Strap. A wide tree saver spreads the load and protects the bark. Never wrap a steel cable or a bare hook around a live tree.
AMBULL D-Ring Shackles. Rated shackles connect straps and rope to the vehicle without a hook that can slip. Carry at least two, and check the rating before every pull.
Read our full recovery-kit guide before your next trip: best winch recovery kit and essential winching accessories.
Troubleshooting
| Symptom | Likely cause | Fix |
| Winch clicks once, motor never turns | Pitted contacts in the old pack, or a loose trigger wire | Test voltage drop across the new unit under load. More than 0.3 volts means a bad connection, not a bad contactor. |
| Winch runs backwards after the swap | Motor leads crossed during the rewire | Swap the two motor leads at the contactor. Never swap the battery leads to fix direction. |
| No click at all after the swap | Trigger wires on the wrong terminals, or no coil power | Check 12 volts at the small terminals when you press the switch, and confirm the wiring against the listing diagram. |
| Contactor sticks on after release | Contacts welded from overload or low voltage | Disconnect the battery at once. Replace the unit, check the battery, and confirm the rating against the table in this guide. |
| Wireless kit works close up but not at distance | Receiver mounted low, behind metal, or in water | Move the receiver high and clear of the bumper steel, and keep it dry. Test from your normal standing position. |
| New unit burns out in weeks | Rating below the winch draw, or a dragging motor | Step up to a 500-amp sealed unit and test the motor draw. A dragging motor kills contactors as surely as it killed solenoids. |
Who should NOT buy these
If your winch already has a sealed contactor, do not buy an eliminator kit. Modern WARN Zeon and VR EVO winches, and most new Smittybilt winches, already use the design this guide swaps to. Replace the contactor like for like instead. If your winch is a 24-volt unit, none of these 12-volt picks fit. Order the 24-volt version of the same part, because a 12-volt coil burns out in under a minute on 24 volts. If the winch motor itself is burnt, test it first with how to test a winch motor and read how to repair a winch motor before spending on switching parts. If you are not comfortable rewiring high-current circuits, have a shop do the swap: a wrong wire at 500 amps is a fire, not a mistake you get to redo.

FAQ
What is a winch solenoid eliminator?
A winch solenoid eliminator is not one product but a swap: replacing a failure-prone four-solenoid pack, or a single open-frame solenoid, with one sealed heavy-duty contactor or a complete control kit. The sealed unit does the same switching job with fewer parts, better sealing and usually a higher current rating, so the click-and-fail cycle ends. Genuine Albright DC88 and SW200 contactors are the best-known parts for this swap.
Does a solenoid eliminator really work?
Yes, when the replacement is correctly rated and wired. A sealed 500-amp contactor carries more current and keeps water and mud off the contacts, which are the two things that kill solenoid packs. It does not fix a burnt motor, a weak battery or undersized cable, so test those first. If the winch clicks but the motor is sound, the swap is one of the most reliable fixes in recovery gear.
What is the difference between a solenoid and a contactor?
A solenoid pack uses separate open solenoids with an audible click, one per circuit, while a modern contactor is one sealed unit with magnetically held contacts. Contactors are quieter, better sealed and usually rated higher, which is why most new winches ship with them. The Albright SW180 and SW200 are the best-known sealed contactors in this class, and the picks in this guide are sealed units in the same style.
Can I replace a four-solenoid pack with one contactor?
Yes, and that is the standard eliminator swap. One sealed reversing contactor replaces all four solenoids, with a failsafe that stops both coils firing at once. The wiring changes, so photograph the old pack, label every cable, and confirm the new terminal layout before you cut anything. Test in and out with no load, and swap the motor leads if the winch runs backwards.
Why do winch solenoids keep failing?
The most common causes are a rating below the winch draw, water and mud on open contacts, and low battery voltage, which makes the motor pull more current. Short, hard pulls with no cooling time add heat that pits the contacts. A sealed 500-amp unit with headroom, mounted high and dry, addresses all three causes at once.
Is the Albright DC88 worth it for a winch?
The Albright DC88 is a sealed reversing contactor rated for motor reversing with a built-in failsafe, and competition winch builders use it for good reason. The catch is supply: we found no verified US Amazon listing for a genuine DC88, so it comes from dealer or industrial supply at a higher price. The sealed 500-amp units in this guide are the buyable alternative that gives most owners the same benefit.
Do I need a wireless remote with an eliminator kit?
No, but it is a useful part of the swap. A wireless kit replaces the remote at the same time as the solenoid, and lets you stand clear of the rope while winching. Keep a wired remote as a backup, because a dead remote battery or a wet receiver should never strand a loaded winch. Test both control paths before the first real pull.
Can a solenoid eliminator damage my winch?
A correctly rated and correctly wired contactor cannot damage a sound winch. The risks are all in the fitting: wrong coil voltage, crossed motor leads, a terminal touching the chassis, or a rating below the motor draw. Follow the maker instructions, keep the housing isolated from the frame, and test with no load first. If any step is unclear, have a shop do the swap.
How long does a sealed contactor last?
A correctly rated sealed contactor that stays dry should last for years of normal recovery use, and the ovsor unit in this guide lists a life of more than 10,000 cycles. Mud, water crossings, corrosion and repeated overload shorten that life. Keep the terminals coated and capped, mount the unit high and dry, and carry the old solenoid as a trail spare until you trust the new unit.
