Installation Notes

Install on the front suspension only and verify the exact vehicle configuration before ordering, especially on models with Autoride, Quadrasteer, electronic suspension, or torsion bar front suspension notes. Some applications require replacement of the suspension strut and coil spring assembly according to the manufacturer’s instructions. Confirm compressed length, extended length, and mount type against the original part before installation.
