The 8” Performance Suspension System is accomplished via one-piece
cast drop down steering knuckles attaching to heavy-duty 1/4” 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. System will provide a true 8 inches of lift
without adjustment to the torsion bars allowing the use of 37” 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.
