Installation Notes and Tips

Verify rear fitment by year, model, and package exclusions before installation. Confirm the compressed length, extended length, and mount types match the original shock: compressed length 16.14 in., extended length 27.36 in., stroke length 11.22 in., lower mount type E2(12X38), and upper mount type S1. Inspect related suspension components, mounting points, and bushings during replacement to ensure the new shock can operate as intended.
