Important notes before you order
- If your vehicle is equipped with both a stock 4" rear block and a top mounted overload/helper spring, select the longer 18.5" Rear U-Bolts.
- Factory wheels fit when paired with factory / original equipment tire size.
- This kit is not designed for dually models, but may me easily adapted to accommodate your truck. Please contact customer support and they will help you find a solution.
- This lift will require replacing your truck's factory rear block to achieve a level stance; total height gained will vary depending on the size of the factory block.
- Exhaust modification may be required to clear the front driveshaft on gas models. See installation instructions for more information.
- Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid / eliminate driveshaft vibration.
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.
