This complete contactor replacement kit includes everything you need to replace your rocker switch and contactor on 2000-3600 lb ATV winches without the hassles of soldering wires. Our proprietary plug-and-play design connects the handlebar rocker switch to the contactor in seconds, and the contactor is labeled for easy installation making it the easiest complete replacement kit available. The heavy-duty cast base won't move or break loose. It's designed to pull heat (heat sync) from the components so there's less risk of over-heating. The rocker switch is the most compact in its class, with high-impact construction made to withstand tough conditions. This set includes universal ATV winch relay/contactor assembly, rocker switch and mounting hardware.
