Description

UMI’s adjustable upper a-arms are designed to excel in Pro-Touring, road race, auto-x and hot street corner carving. The race quality rod ends provide shim-free camber and caster adjustment along with ultimate smooth travel. This arm features a relocated ball joint pad to increase caster and improve stability and steering feel as well as a shortened cross shaft to ball joint distance. We recommend the 4056 arm for all racing applications. Arm must be used with tall spindles when using standard height ball joints. 100% manufactured, tested and raced out of Philipsburg, PA – USA. UMI Performance bump steer kits relocate the outer tie rod pivot point which results in decreased toe change during wheel travel. Standard kits include sleeves, rod ends, jam nuts and high quality, direct fit tapered studs. Race kits require drilling of the spindle and include heavy duty 5/8 bolts. Race kits are recommended for autocross and road race applications while standard kits are indicated for street/strip use.
