Choose the Correct Polaris RZR Pro S Kit
If the rebuild also requires intake and exhaust valves, consider the Polaris RZR Pro S Master Engine Rebuild Kit. When the existing cylinder and valves remain usable, compare the Polaris RZR Pro S Engine Rebuild Kit.
Verify the Rebuild Scope
Inspect the cylinder head, engine cases, oiling system, and reusable components before assembly. Then, measure bearing and piston clearances using the correct service specifications. Replace any additional worn components before completing the rebuild.
