Installation Notes and Tips

Verify rear suspension type before ordering. This shock fits normal suspension Grand Cherokee models only and does not apply to air, electric, load leveling, or sport suspension configurations listed in the fitment notes. KYB recommends replacing the strut mount, part number SM5684, to reduce the chance of noise and vibration. Confirm compressed length, extended length, and mount style against the original part before installation.
