With an all new platform for 2007 GM Fullsize SUV's and SUT's, Fabtech has developed multiple systems that provide everything from a stock like ride up to a mega dampening offroad suspension. Common to all 2007 GM systems is Fabtech's legendary one piece high arched lower crossmember design with an integrated differential skid plate for solid support of the front suspension. Special attention was given to the design of replacement extended length steering knuckles to keep the track width of the vehicle near stock while retaining turning radius for easy maneuverability in tight areas.
