RZR 900/1000 XP cylinder head rebuild

Rebuild your worn out RZR 900 or 1000 cylinder head. The OEM head often ingests dirt and wears out rapidly. We can rebuild it to better than stock.

What we do.
-Clean and inspect head.
-Dissemble and assemble if needed.

Intake and exhaust guides:
-These often wear out from high heat and dirt ingestion. We replace the stock factory guides with much higher quality Kibble white bronze guides. These are hand reamed to fit which helps ensure the best seal, and longest life. If we are replacing valve guides a valve job is a MUST!!!

Valve job:
-We perform a multi-angle cut on the valve seats to help promote flow, and match the seats accordingly.

Assembly of your head.
-We can ship you your head assembled or in pieces ready for you to assemble.

Set valve lash:
-When we cut your valves and seats the valves need to be adjusted to get back into proper spec. If we assemble your head we can set these clearances for you.

Please Call for Availability


The Polaris OEM valve guides are fast wearing (junk). The exhaust valve guides usually wear first. This allows your valve to move in the guide side to side. If you take your head off for any reason we recommend you remove a exhaust valve assembly and check the valve for movement. Polaris does not offer replacement valve guides. We install much higher quality custom Kibble White valve guides.
