UMI Performance 4056-2-R Adjustable Upper Front Control A-Arm Powder Coat - Red

The UMI Performance 4056-2-R is an adjustable upper front A-arm engineered for A-body Pro Touring and performance builds. Hand-built in Philipsburg, PA using U.S. materials, this arm is designed to deliver measurably improved front-end handling through a relocated ball joint pad and precision-adjustable rod ends. The red powder coat finish provides a durable, show-quality appearance.

The arm features a laser-cut ball joint mounting pad that positions the upper ball joint ½" higher than stock, improving the camber curve for increased front-end grip. The ball joint plate is also relocated rearward, generating increased caster and sharper steering feel — without requiring excess alignment shims. Two precision rod ends threaded onto a 4130 chromoly (CrMo) CNC-machined and zinc-plated cross shaft allow for easy arm length adjustment. The entire assembly is TIG welded for superior structural integrity and clean aesthetics.

Important Notes: The UMI 4056-2 upper A-arm is designed for lowered vehicles. Use with stock-height or raised (cargo coil) vehicles is not recommended, as the bump stop may contact the cross brace. This arm is designed to work with factory-height spindles and increases effective spindle height by ½". May also be used in conjunction with select aftermarket lower A-arms and spindles — contact UMI Performance to confirm compatibility before ordering. UMI Performance is not responsible for fitment issues arising from the use of incompatible components.
