Installation Notes and Tips

Ensure compatibility with Toyota 4Runner models before installation. The shock absorber uses a 19mm eye lower mount and stem upper mount, so verify mounting hardware and bushings are in good condition. Since this is a non-adjustable shock, no damping adjustments are necessary. Proper torque specifications should be followed during installation to maintain suspension integrity and safety.
