PRODUCT DESCRIPTION

UMI’s adjustable upper a-arms are designed for high performance in Pro-Touring, road race, auto-x, and hot street driving. The race quality rod ends provide smooth camber and caster adjustment without the need for shims. This arm features a relocated ball joint pad for increased caster and improved stability and steering feel. It also has a shortened cross shaft to ball joint distance. The 4056 arm is recommended for all racing applications, and must be used with tall spindles when using standard height ball joints. Manufactured, tested, and raced in Philipsburg, PA, USA.

Fitment Note: Upper a-arm P/N 4056-1 includes standard height ball joints and must be used with A-Body tall spindles. In most cases shims are not needed, but may still be required on some applications.
