# UMI Performance 70-81 GM F-Body Tubular Upper & Lower A-arm Kit

UMI’s 2nd Generation F-Body a-arms are perfect for the F-Body enthusiast seeking to improve the performance and appearance of their front suspension. This kit features caster relocation of 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 CrMo offset cross shafts to reduce the amount of shims required when setting camber. A pancake style polyurethane bump stop and high quality ball joint is included. 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. UMI’s double shear sway bar end links are included and work nicely with UMI P/N 4035 sway bar and also most aftermarket stock eyelet type sway bars. Available in UMI red or gloss black powder coat. 100% designed, manufactured and raced with pride in Philipsburg, PA - USA.
