Mechanical Tensioner Conversion RZR

Are you tired of hearing the rattle at startup from your Polaris ProStar engine? Do you ever wonder what causes it? Polaris used a hydraulic timing chain tensioner in their 900 and 1000 engines from 2014 to 2020, depending on the model. This design means that when you start your engine before it builds oil pressure, the timing chain can rattle around and create noise. As the timing chain stretches over time, there's even a possibility of it jumping timing and damaging your engine. 

Don’t wait for this to happen to you! This replacement timing chain tensioner is designed to fit in place of the factory hydraulic part and utilizes a proven dirt bike-style tensioner. It will help reduce engine noise and prevent catastrophic engine failure due to improper timing.
