When recovery operations get extreme, the fluid in an hydraulic winch starts to heat up. This not only affects the task at hand, but can also cause damage to the winch. To keep the winch cool and running smoothly, installing a Winch Cooler on your winch can continuously circulate the hydraulic fluid through the finned cooler, dramatically dropping operating temperatures, keeping the winch cool during extended use. The kit, which is designed for Mile Marker winches, comes with cooler, hoses, clamps and all the required hardware for installation. Measures 5″ x 12″ x .5″ and is equipped with 3/8″ hydraulic lines. Universal fit, not vehicle specific.
