Kroyer Racing Engines Polaris Performance Cam & Valve Train Kit.

Designed to fit the stock head/valve configuration. Performance Valve Train Kit for Polaris RZR, RZR-S, RZR4 and Sportsman 800 motors. Provides increased overall performance and reliability for safe engine RPM’s up to 7000.

Replace that lazy, stock cam and valve train with the Kroyer Racing Engines Valve Train Kit; Race proven Performance. Some companies just sell a cam - We insist on selling a complete kit as opposed to individual parts because the stock valve springs, lifters and push rods are not adequate to operate with a higher lift/ duration camshaft or higher RPM and it is important for the performance and reliability of the motor that all parts be replaced/upgraded at the same time. It is also important that all valve train parts be designed to the same specification (by the same company) to ensure precise and correct fitment and function.
