The Mile Marker Hydraulic Winch System has been a self-recovery icon for over 15 years. This legendary system utilizes the vehicle's OEM power steering pump as its power source. Everyday, more than 200 million power steering pumps operate flawlessly. Used in all types of vehicles, under every condition, from 50 below to 135 degrees above, the pump must perform for years without service or adjustment. It has to withstand every type of abuse without failure. Having a built-in governor (the pressure relief valve), it is impossible to overload or overwork the pump. This is why harnassing the hydraulic power steering pump has become the best choice for recovery power!
