Ensure compatibility with Jeep Wrangler models before installation. The shock absorber features eye-type mounts that require 12.8mm mounting hardware. Since this is a non-adjustable shock, no damping adjustments are necessary. Verify collapsed and extended lengths to confirm fitment within your vehicle’s suspension travel range. Professional installation is recommended to ensure proper torque specifications and alignment.
