The 8in Performance Suspension System is accomplished via one-piece cast drop down steering knuckles attaching to heavy-duty 1/4in thick, high arched lower control arm crossmembers with tubular upper control arms. Fabtech's combination of steering knuckle, high arched crossmembers and upper control arms provides an excellent ride quality with high ground clearance. This system will provide a true 8 inches of lift without adjustment to the torsion bars allowing the use of 37in tall tires. The front differential is properly relocated to eliminate front driveshaft vibration on 2001-06 vehicles with the stock driveshaft. On late model 2007-08 vehicles with Magna 1625 transfer cases the system requires the use of a CV front driveshaft to address high speed 4WD use. New tubular upper control arms fit into the stock frame pockets using urethane bushings. Upper control arms include double shock mounting tabs for integration with Fabtech's optional front dual shock hoop system. The front suspension is completed with an differential skid plate, tubular crossmember supports and impact struts while the torsion bar drop down brackets properly align the torsion bars to the relocated stock lower control arms. The rear suspension is lifted using a 4'' block kit with 2'' add a leafs. The system is completed with rear bump stop brackets and a rear driveshaft carrier bearing drop bracket.
