Important notes before you order
- Determine if your truck is equipped with standard (2-leaf main) or heavy payload (3-leaf main w/overload) factory rear leaf spring packs.
- Standard 2-leaf main applications will require kit # F48, heavy payload 3-leaf main w/ overload applications will require kit # F50. See "learn more" example image.
- Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid / eliminate driveshaft vibration.
- Fits SRW models only
- 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.
