UMI polyurethane rear end housing bushings replace worn rubber units for 1979–2004 Ford Mustang applications. The kit swaps the two upper rear end differential bushings in the rear end "ears," improving ride quality and control for street and drag use. The outer metal shell must be reused and installation typically takes about 2–4 hours.
