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.

Built 2" x .250-wall DOM tubing while offering better NVH isolation with large factory style rubber bushings at both ends. The integrate a drag bar flip kit to flatten out the steering angle for improved handling as well as provide front and rear track bar braces.
