Our 6in system for 2001-10 GM HD's has been designed to provide superior suspension performance for daily driving or for offroad. This is accomplished using our proven one piece lower control arm crossmembers and extended length steering knuckles with a multitude of shock absorber options. The 1/4in thick arched lower control arms crossmembers include an integrated front differential skid plate, crossmembers support tubes and rear impact struts to distribute front suspension impact loads through the frame evenly. A new knuckle design was introduced in 2007 with this system that provides reduced track width to keep the tires under the fenders. This system also includes torsion bar drop mounts, extended length sway bar links with urethane bushings, front and rear bump stop brackets, and rear blocks.
