This Polaris RZR 800 Power Steering Kit is a bolt on system that significantly reduces the steering effort and diminishes bump steer. The power steering unit mounts under the dash and does not decrease your leg room. This is an all electric system that uses electronic sensors and an on board computer to drive an electric worm gear motor which is connected to the steering system of your RZR. The system uses a torque sensor to sense the amount of steering done by the rider and transmits this signal to the on board computer which relays the amount of turning pressure to apply to the steering system. It decreases rider fatigue and also assists in reducing the jarring and kick-backs. The system components are sealed to give water and dirt protection while you are on the tough terrain. The LED light indicator is for system diagnosing in case of component failure. This is a low maintenance system with only minor lubrication needed. There is an overheating protection system built in. Get a more comfortable ride and reduce fatigue with this RZR 800 Power Steering Kit.
