FABTECH 6" RTS System w/ Dirt Logic Shocks for 2011-17 GM C3500HD 2WD/4WD

Fabtech?s cutting edge RTS? system has now been developed for the all new GM HD platform. The 6" RTS? 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. Use 35/13.50R18 tires w/ 18x9 wheels w/ 5 3/4" BS w/ minor trimming. Use 35/13.50R20 tires w/ 20x10 wheels w/ 5 3/4" BS w/ minor trimming. Use 355/65R18 tires w/18x9 wheels w/5 3/4" BS w/minor trimming.
