Important notes before you order
- Exhaust modification may be required to clear front driveshaft (gas only)
- Although extremely rare, front driveshaft vibration may occur
- If equipped with 2-piece rear driveshaft, carrier bearing drop will be required (ZONF5401)
- Front driveshaft u-joints may max out at full droop. If so, a new front driveshaft will be required.
- If equipped with rear sway bar, extended sway bar links will be required. (ZONF5009)
TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.
