The Fabtech 4" front lift kit for the Chevy Silverado, GMC Sierra 2500HD, 3500HD was developed using replacement upper control arms constructed from 1.50 OD .120 thick wall DOM tubing. These attach to heavy duty ductile iron steering knuckles. Forged adjusting keys provide the proper amount of lift while keeping the factory torsion bars in the stock position.
Since the stock lower control arms, torsion bars and front differential do not need to be relocated, there is no loss of ground clearance with this system. Installation of just the front components will level the stance of your vehicle compared to the nose down factory rake. For vehicles that require or prefer a slight rake, a 1" block kit is offered separately. This package also includes front and rear Dirt Logic shocks.
