- Reduced control from worn rear shock damping
- Harsh or inconsistent rear suspension response
- Rear suspension instability during towing or hauling
- Uneven ride quality caused by aging shock absorbers
Installation Notes
Verify rear suspension configuration before ordering, especially Z85 Chassis Package, Off Road Suspension, and electronic suspension exclusions. Confirm compressed length, extended length, and stroke length against the original shock to ensure proper travel and mounting fit. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
