Our 4 Ultimate System provides less lift than our 6 RTS(TM) system but still allows use of 33 or 35 tall tires with cutting for street and offroad use. We have developed this system 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 (2500HD Part # FTS21110) (3500HD Part # FTS21111).This Part Fits: Year Make Model Submodel 2015-2019 Chevrolet Silverado 2500 HD High Country 2011-2019 Chevrolet Silverado 2500 HD LT 2011-2019 Chevrolet Silverado 2500 HD LTZ 2011-2019 Chevrolet Silverado 2500 HD WT 2015-2019 Chevrolet Silverado 3500 HD High Country 2011-2019 Chevrolet Silverado 3500 HD LT 2011-2019 Chevrolet Silverado 3500 HD LTZ 2011-2019 Chevrolet Silverado 3500 HD WT 2015-2019 GMC Sierra 2500 HD Base 2011-2019 GMC Sierra 2500 HD Denali 2011-2019 GMC Sierra 2500 HD SLE 2011-2019 GMC Sierra 2500 HD SLT 2011-2014 GMC Sierra 2500 HD WT 2015-2019 GMC Sierra 3500 HD Base 2011-2019 GMC Sierra 3500 HD Denali 2011-2019 GMC Sierra 3500 HD SLE 2011-2019 GMC Sierra 3500 HD SLT 2011-2014 GMC Sierra 3500 HD WT

Fabtechs cutting edge RTS(TM) system has now been developed for the all new GM HD platform. The 6 RTS(TM) 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(TM) 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(TM) system allows the use of both 18 and 20 diameter wheels.This Part Fits: Year Make Model Submodel 2015-2018 Chevrolet Silverado 2500 HD High Country 2011-2018 Chevrolet Silverado 2500 HD LT 2011-2018 Chevrolet Silverado 2500 HD LTZ 2011-2018 Chevrolet Silverado 2500 HD WT 2015-2016,2018 Chevrolet Silverado 3500 HD High Country 2014-2016,2018 Chevrolet Silverado 3500 HD LT 2014-2016,2018 Chevrolet Silverado 3500 HD LTZ 2014-2016,2018 Chevrolet Silverado 3500 HD WT 2015-2019 GMC Sierra 2500 HD Base 2011-2019 GMC Sierra 2500 HD Denali 2011-2019 GMC Sierra 2500 HD SLE 2011-2019 GMC Sierra 2500 HD SLT 2011-2014 GMC Sierra 2500 HD WT 2015-2016,2018-2019 GMC Sierra 3500 HD Base 2014-2016,2018 GMC Sierra 3500 HD Denali 2014-2016,2018 GMC Sierra 3500 HD SLE 2014-2016,2018 GMC Sierra 3500 HD SLT 2014 GMC Sierra 3500 HD WT
