The Sparks Racing Drive Chain Tensioner for the Polaris RZR 170 is the solution every RZR 170 owner has been looking for to eliminate chain-slap and jumping teeth. Sparks Racing has spent 2 race seasons testing this kit on several race cars to ensure proper function and durability. This kit will fit the OEM swing arm and most aftermarket swing arms. If running an aftermarket swing arm skid plate, some trimming for roller clearance may be required.
