TRU specialist notes

- 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.
