Important notes before you order
- Auxiliary Shocks? If your vehicle is equipped with factory auxiliary front shocks, you will need to order auxiliary shocks to complete your kit. Add in configuration / checkout.
- On some models, the front driveshaft may need to be clearanced at the double cardan joint to prevent binding.
- Some models may require the transfer case drop kit C5001 listed in the accessories to alleviate driveshaft vibration.
- The front exhaust cross-over pipe may need to be modified to clear the front driveshaft on some models.
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.
