The Prothane rear differential bushings in red are replacement drivetrain mount components for 1983–1987 Chevrolet S10 pickup and Blazer 4WD applications. These bushings restore the differential mounting points to reduce excessive movement and maintain proper drivetrain alignment. Use them when replacing deteriorated factory bushings to improve stability and preserve correct driveline clearance.
