Good To Know

Q: Do these mount in the factory rear locations? A: Yes, they are built to the OEM 84178213 mounting configuration for a direct rear installation. Reuse the factory hardware unless it is damaged.

Q: Should both rear shocks be replaced together? A: Replacing the pair at the same time keeps damping balanced side to side. It is also the standard practice when one shock has failed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
