UMI 4056-2-R 64-72 A-Body Front Upper A-Arms, Adjustable, Red

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 ½” 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 Chromoly 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 ½” taller upper ball joint. A laser cut bump stop brace completes the arm. If used for drag racing, the arm can also accommodate a travel limiter. The 4056-2 a-arm is designed to work with factory height spindles and increases spindle height by ½”. UMI’s a-arm set is available in beautiful red or black powder coat and is hand built in Philipsburg, PA – USA of US materials.

NOTE : The UMI 4056-2 upper a-arm is designed to work primarily with lowered cars. We do not recommend using the 4056-2 with cargo coils or above stock height cars, as the bump stop may contact the cross brace. UMI’s adjustable upper a-arms with taller ball joints are designed to work with factory height spindles. UMI is not responsible for fitment issues which may arise from using incompatible components.
