To enhance our extensive line of Super Duty suspension systems we have developed an entry level 4” Budget System. 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. 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.
