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.

Overview
Fabtech's Crawler long arm coil systems replace all eight of the link arms with extended length units to allow for smooth operation at extreme angles. The link arms are mounted up high on the frame to increase ground clearance without the need to bend the Links as with other long arm systems on the market. Construction of the link arms is nothing short of the best heavy duty units you can buy. Each lower link is built from 2'' OD .313 thick wall DOM that is so strong Fabtech provides a warranty against bending. Link arms are internally threaded to accept the ground breaking Fabtech 5 Ton Joint that is guaranteed never to wear out. Weld on 1/4'' thick steel Track Bar brackets provide the proper roll center front and rear and will not fail leaving you stranded. This system utilizes Fabtech's Standard coil springs that are a single rate design and provide great all around suspension performance. Factory load carrying capacities are retained in these quality springs. Includes 8 Long Arm Links &
