UMI Performance 64-72 GM A-Body Front Upper A-arms Adjustable 0.9in Taller Ball Joints
Today’s Pro Touring A-bodies are handling like never before. Achieve your goal of awesome handling with UMI’s new adjustable upper a-arm. This arm precisely locates a 0.9” taller upper ball joint which in turn improves the camber curve and results in more front end grip. The advanced design of the a-arm also relocates the ball joint plate rearward for increased caster and improved steering feel. The machined CrMo cross shaft holds two precision rod ends which are used to adjust the arm sections. These arms are TIG welded to the laser cut ball joint pad which houses a 0.9” taller upper ball joint. A laser cut bump stop brace completes the arm. If used for drag racing, the 4056-3 can also accommodate a travel limiter. The 4056-3 a-arm is designed to work with factory height spindles and increases spindle height by 0.9”. The 4056-3 a-arm set is available in beautiful red or black powder coat and is hand built in Philipsburg, PA – USA of US materials.
