Important notes before you order
- Does NOT work with all wheel drive (AWD) models.

- Use a 1/4" wheel spacer to accommodate factory 20" wheels; refer to the provided "Max Tire Size" for 20" wheels for tire sizing.
- Stock tires & wheels can be installed back on the vehicle, but larger tires can NOT be installed on factory wheels.
- Always check for wheel and tire clearance before driving the vehicle.
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.
