Installation Notes and Tips

Verify mount style, compressed length, and extended length before installation. This shock uses a stem upper mount and a loop bushing lower mount, so confirm the vehicle’s existing hardware and suspension configuration match the listed fitment. For 1978-1979 Ford Bronco and Ford F-150 front applications, check whether the vehicle has factory equipped quad shocks or the non-quad-shock front left position before ordering.
