This center carrier bearing assembly is designed as a direct replacement for the factory carrier bearing used on select Polaris RZR 800 and Ranger 800 Crew models. Installed in the driveline to support the driveshaft, the bearing helps maintain proper alignment while reducing vibration and driveline noise that can occur as the original bearing wears. Supplied as a complete assembly with the bearing pre-installed in the steel carrier, this unit installs in the factory location using standard service procedures. Intended for routine maintenance or repair, it helps restore normal driveline operation and reduce the risk of damage caused by excessive bearing play. Sold individually.
