The SDI Sprocket Damper Assembly for the 2014–2021 Polaris RZR 170 EFI is designed to reduce drivetrain vibration and stress by introducing controlled flex between the sprocket and hub. This innovative design helps absorb shock loads, creating smoother power delivery while protecting drivetrain components from excessive strain.
By allowing a slight amount of movement under load, the damper assembly improves durability and performance during demanding conditions such as hard acceleration and rough landings. The result is a more refined drivetrain feel and increased reliability for riders pushing their RZR 170 on the track or trail.
