UMIís 2nd Generation F-body performance a-arms are perfect for the F-body enthusiast seeking to improve the performance and blur the lines between race and street use. 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 potential is 8+ degrees. The spindle pin location remains unchanged so fender clearance is like stock. The adjustable upper a-arms reduce the need for shims in addition to providing an easy way to achieve desired camber and caster settings. They also include a tall ball joint to improve camber gain. Upper and lower a-arms are designed to allow proper suspension movement and approved steering response using UMI built Delrin bushings and Teflon lined rod ends. 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. UMIís double shear swivel 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.
