Tire & wheel options for 4" & 6" lift
35/13.50R18 tires on18x9 wheels with 5-3/4" BS w/ minor trimming
35/13.50R20 tires on 20x10 wheels with with 5-3/4" BS w/ minor trimming
Fabtech’s cutting edge RTS system utilizes a patent pending bracket system that keep the torsion bars raised up, in the stock location. This feature provides superior ground clearance at the frame as there are no torsion bars hanging down to become high centered on or damaged when offroading. The 6” RTS system has been designed with unitized bracketry to retain the four front compression stops of the vehicle as GM intended. This distributes impact loads across a wide section of the frame rather than at a single point.
High arched crossmembers and front differential skid plate are constructed of 1/4” thick steel to resist bending from hard front suspension impacts. Only 1/4” thick steel provides the rigidity and strength necessary to relocate the torsion bars, bump stops and lower control arms properly. Minimal heavy duty bracketry allow for a fast installation time with only two holes to drill and no cutting of the front diff housing. The 6” RTS system allows the use of both 18” and 20” diameter wheels. No driveshaft modification required. Retains stock track width. Compatible with Stabilitrak.
Fabtech's 4” Ultimate System provides less lift but still allows use of 35” tall tires for street and moderate offroad use. This system was developed utilizing replacement upper control arms constructed of 1.50” OD .120” thick wall DOM tubing that attaches to heavy duty Fabtech ductile iron steering knuckles. The factory torsion bars remain in the stock position and use new forged adjusting keys to provide the proper amount of lift. There is no loss of ground clearance with this system as the stock lower control arms, torsion bars and front differential do not need to be relocated. This 4” Ultimate System will level the stance of the vehicle compared to the factory nose down rake with no change to the rear suspension. For those customers that require a factory nose down appearance an optional 1” rear block kit is available. No cutting, drilling, welding or driveshaft modification required.
