Important notes before you order

  1. If vehicle is equipped with a front sway-bar, drop brackets are recommended.
  2. (sku: 1019) vehicles with factory quad shocks (2 front shocks per side) will simply use a single aftermarket shock.

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.
