POLARIS RZR Performance Valve Spring Kit for O.E. Head/Valves

KROYER RACING ENGINES POLARIS VALVE SPRING KIT (stock head) RZR 800

Valve springs play a key role in the proper operation of your engines valve train. In order to function correctly, the valve spring must be of proper length, rate and strength in order to allow the valves to effectively follow the profile of the cam with out any loss in power throughout your engines entire RPM range. A spring that is too soft or too stiff will not allow for consistant cam and valve timing resulting in loss in performance or even worse…

The Kroyer Racing Engines valve spring kit was designed and built to exact tolerances from special high tensile strength alloys.

- Springs - Bases - Light Weight Retainers
