PRODUCT OVERVIEW

Our 4 inch Ultimate System provides less lift than our 6 inch RTS system but still allows use of 33 inch or 35 inch tall tires with cutting for street and off-road use. We have developed this system utilizing replacement upper control arms constructed of 1.50 inch OD .120 inch 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 inch 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 inch rear block kit is available. Use 33/12.50R18 tire w/ 18x9 wheels w/ 5 3/4 inch BS w/ minor trimming. Use 33/12.50R20 tire w/ 20x9 wheels w/ 5 3/4 inch BS w/ minor trimming. Use 35/13.50R18 tire w/ 18x9 wheels w/ 5 3/4 inch BS w/ fenderwell cutting. Use 35/13.50R20 tire w/ 20x9 wheels w/ 5 3/4 inch BS w/ fenderwell cutting. Will not fit standard cab models.. Will not fit 17 inch wheels. Requires cutting of fenderwell sheetmetal for use with 35 inch tires
