Our Throttle Pedal Kits for the Polaris RZR XP 900 are designed for more comfort and control while you are out on the trail or where ever you use your UTV. They help eliminate fatigue during those long trail rides for a more enjoyable experience. The Sport Model is an assembly made completely of engineering grade polyurethane suited for the recreational user. It is highly durable, allowing for years of trouble free operation. The Pro Model has all the same features of the Sport Model except for the differences in the pedal. For the Pro, we bond the polymer to a powder coated aluminum substrate creating an almost indestructible assembly, with a higher end finish.
