3.5in. ULTIMATE SYS

The 4 Budget System utilizes the factory front coil springs with a steel upper spacer providing 4 of lift. Radius Arm drop brackets retain the factory arms with correct caster setting for the increase ride height. System includes a Trac Bar relocation bracket that has been designed to center the axle under the vehicle and still works properly with the factory Pitman Arm. This eliminates the need to replace the Pitman Arm resulting in a lower cost and faster installation time. Rear lift is accomplished with lift blocks and extended length u-bolts. System allows installation of 35 tall tires with required inner fenderwell trimming for adequate tire clearance for street driving and light offroad use.

Our 4in Ultimate System provides less lift than our 6in RTS system but still allows use of 33in or 35in tall tires with cutting for street and offroad use. We have developed this system utilizing replacement upper control arms constructed of 1.50in OD .120in 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.
