Important notes before you order
- Dually Model Only.
- Diesel Model Only.
- Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift drive-line angles and avoid / eliminate driveshaft vibration.
- Due to taller factory ride height, Tremor models will not net full advertised lift height. Final ride height will be the same as standard models
- Wheel and Tire:
- 37x12.50 tires may require minor trimming.
- Factory wheels fit when paired with factory / original equipment tire size.
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.
