    Front Upper & Lower A-Arm Kit

    UMI’s 2nd Generation F-body a-arm kit, designed to make your classic cruiser feel like modern muscle. Increased positive caster combined with improved camber curve and low friction Delrin bushings make for a well-tuned front end. Increased caster is achieved relocating both the upper and lower ball joints to enhance steering feel and improve high speed stability. As designed, the caster range is 5-7 degrees. The spindle pin location remains unchanged so fender clearance is like stock. The upper a-arms include offset chromoly cross shafts to reduce the amount of shims required when setting camber as well as a tall ball joint to improve camber gain. Upper and lower a-arms are assembled with UMI built Delrin bushings to allow proper suspension movement. A pancake style polyurethane bump stop is included to control suspension droop. The heavy duty lower spring bucket accepts factory and aftermarket coil springs as well as the popular hybrid coilover units. Laser cut UMI reinforcement plates add a great appearance and excellent strength.

    Precise Handling & Smooth Suspension

    Improve the performance of your vehicle with UMI Performance Upper & Lower Tubular A-Arms. The lower a-arms work with most popular springs and coil-overs with tubular construction with greaseable polyurethane bushings for precise handling and smooth suspension. Optional Delrin bushings offer additional precision and decreased friction. The ball joint mount is angled to permit usage with lowered vehicles along with additional wheel clearance. The upper a-arms include Delrin bushings with billet chromoly cross shafts. The relocated ball joint mounting pad increases caster, steering feel and stability without excessive shims and can be loaded with 1/2" taller upper ball joints for improve camber performance. Available powdercoated red or black. .
