- RZR 900 2011-2016
- RZR 1000 2014-2016
- Or any engine that has a hydraulic style tensioner thread in tensioner
The OEM hydraulic tensioner requires oil pressure to build tension, when the engine is cold it takes a few seconds for oil pressure to build and get tension on the cam chain. In these few seconds, the engine is vulnerable to skipping teeth on the cam sprockets and result in the engine being “out of time.” When this happens, the piston can come into contact with the valves and result in bent valves, or even a damaged piston.
This upgrade is a ratcheting style tensioner which means that no oil pressure is needed to keep the cam chain tight, thus eliminating the chance of the engine jumping time. In addition if you have a slightly worn cam chain and you want to eliminate that loud chatter on start up, this tensioner also will take up a few extra thousandths of slack in a stretched chain and significantly reduce any “chain slap” or “top end chatter.”
