DSE Weight Jack Lower Control Arm Kit (1979 - 1993 Ford Mustang / 1979 - 1986 Mercury Capri) 030344DS
Give your Fox Body front suspension the geometry, adjustability, and clearance needed for serious performance with the Detroit Speed Weight Jack Lower Control Arm Kit 030344DS. Designed to replace the factory lower control arms and front springs, this system combines tubular control arms with an integrated Weight Jack setup that lets you fine-tune ride height and corner balance without disassembling the suspension. The tight-profile control arm design also maximizes wheel and tire clearance at full steering lock, making this an especially valuable upgrade for aggressive street, autocross, and track builds using a strut-style front suspension.
The 030344DS uses SN95 Mustang ball joints and greaseable Delrin bushings for smooth suspension articulation, durability, and precise control. Its Weight Jack system accepts common 2.5-inch ID springs, expanding your spring-rate tuning options as the car and its intended use evolve. Detroit Speed includes 7-inch free length, 700 pounds per inch springs that have been tested and tuned for balanced street and autocross performance. Included bushing spacers also allow the control arms to be installed in either the standard or forward position, with the forward location providing increased caster for improved stability and steering feel.
