KanSmart 12V 250A Winch Solenoid Relay & Switch Kit — 3000–5000 lb ATV/UTV, weather-resistant, pre-assembled

KanSmart 12V 250A winch solenoid relay and switch is a direct-fit replacement kit that restores reliable power control to 12V ATV and UTV winches rated around 3000–5000 lbs.

When a winch contactor or switch fails, you lose the ability to spool in or out reliably. This KanSmart assembly combines a weather-resistant 250A solenoid relay, a hardened rocker switch and protective caps into one ready-to-install kit engineered to match common OEM references. It’s built to replace worn or broken relays from many popular brands and designed for simple bolt-in installation so you can get back to trail work or recovery duties without fuss.

Will this solenoid work with my ATV or UTV winch?

The KanSmart unit is compatible with most 12V winches and electrical systems used on ATVs, UTVs, SUVs and light 4x4s. It references several OEM part numbers and lists broad manufacturer compatibility to help determine fit.

• Voltage: 12V nominal, current capacity: 250A continuous load handling.
• Fits winches in the 3000–5000 lb class used on many ATV/UTV setups.
• Cross-references: 63070, 62135, 74900, 2875714, 70715 for fit guidance.
• Works with brands including Polaris, WARN, Ramsey, Superwinch, Smittybilt and more.

How durable is the relay and switch in outdoor conditions?

KanSmart manufactures the relay housing from solid steel with a powder-coated finish to resist corrosion and abrasion. Components are tested before shipping and the kit includes protective caps to shield terminals from moisture and dirt.

• Powder-coated steel housing to reduce rust risk and improve longevity.
• 6 protective terminal caps included to limit exposure to water and debris.
• Pre-assembled switch parts in the upgraded version streamline installation.
• 100% electrical testing before shipment for quality assurance.

How easy is the installation and what’s in the package?

The kit arrives with the relay, a matching rocker-style winch switch, six protective caps and step-by-step installation instructions. The latest version has fixed switch components pre-assembled so you won’t need extra assembly tools beyond basic hand tools.

• Includes: 1 x 250A winch solenoid relay, 1 x winch rocker switch, 6 x protective caps, instruction sheet.
• Pre-assembled switch parts reduce install time and user assembly errors.
• Designed for straightforward bolt-in replacement using existing mounting points.
• Customer support and a 1-year warranty from KanSmart for added confidence.

What electrical and safety considerations should I observe?

Match the relay voltage and amp rating to your winch specifications and use proper gauge wiring and secure connections. Always disconnect the battery before replacing the solenoid and follow the supplied instructions or a qualified technician’s guidance.

• Confirm 12V system compatibility and that 250A meets your winch peak/continuous needs.
• Use correct wire gauge and tighten terminals to prevent heat or voltage drop.
• Follow battery-disconnect safety steps and verify polarity before final operation.
• Inspect protective caps and housing seals periodically after off-road use.

Who is this for: The KanSmart 12V 250A winch solenoid relay & switch kit is intended for ATV and UTV owners, off-road enthusiasts, fleet operators and anyone who needs a rugged, tested replacement for a failed winch contactor. It’s especially useful for users of 3000–5000 lb winches who want a weather-resistant, pre-tested assembly that’s easy to install and backed by a one-year warranty.
