Product Details

6" Performance System Lift is accomplished via one-piece cast drop down steering knuckles attaching to heavy-duty 1/4" thick, high arched lower control arm crossmembers. Fabtech’s combination of steering knuckles and high arched crossmembers provides superior ground clearance for the true offroader. The front differential is relocated with a cradle style bracket using bushings at just the proper angle to allow the use of the factory front driveshaft, without vibration on Autotrac models. Solid steel billet sway bar end links with urethane bushings retain the factory front sway bar angle. The stock upper control arms and steering centerlink are retained in the factory position and do not have to be removed for installation. The front suspension is completed with crossmember impact struts and torsion bar drop down brackets. Rear lift is accomplished with a 4" block kit and 2" add a leaf.

Fabtech Motorsports off-road racing team puts their systems to the ultimate test every race. The experience gained from racing goes in the design and fabrication of each suspension system. During the development phases of each Fabtech Suspension application the two most critical steps are the fit check process and the driving evaluation. Understanding that truck manufactures cannot make every vehicle exactly the same, Fabtech takes the time to fit each new system to multiple vehicles. This allows Fabtech to find the factory inconsistencies and build in the tolerances so that each Fabtech system fits easily and properly to every vehicle. To ensure dependability and performance Fabtech tests each of their systems in a variety of driving conditions, on and off-road. After extensive hours of testing, each component is evaluated for proper functionality and strength. Fabtech is then able to dial in each suspension system for maximum performance. Lift your truck with a proven winner, Fabtech.
