RZR 170 Sprocket Output Shaft Bearing #2

Keep your Polaris RZR 170 running smoothly with the Genuine OEM Output Shaft Ball Bearing (Part # 0454559).

This precision ball bearing is a critical component in the Gear Shaft Output assembly. It supports the output shaft gear, allowing it to rotate freely while handling the torque and loads from the transmission to the final drive sprocket. Over time, bearings can develop play, noise, or fail due to heat, contamination, or high-hour use — replacing it restores quiet, efficient operation and protects the surrounding gears and seals.

Fitment: Fits all Polaris RZR 170 models from 2009 to 2021 (including EFI variants). Located as Ref #2 in the official DRIVE TRAIN, GEAR SHAFT OUTPUT diagram.
