• Uneven ride quality in light truck rear suspension service

Installation Notes

Verify compressed length, extended length, and mounting style before installation. Confirm the rear position and compare the upper cross pin mount and lower loop bushing and sleeve mount to the original shock absorber. Inspect surrounding suspension components for wear before replacing the shock.
