UMI Performance 4056-3-B Adjustable Upper Control Arms for A-Body Pro Touring

The UMI Performance 4056-3-B adjustable upper A-arms are engineered for Pro Touring A-body vehicles seeking superior handling performance. These precision-built control arms feature a relocated ball joint pad that positions a 0.9-inch taller upper ball joint, improving the camber curve for increased front end grip while adding caster for enhanced steering feel.

Key Features:

• Constructed from 0.120-inch wall thickness, 1.250-inch diameter DOM tubing for exceptional strength
• TIG welded construction with laser cut ball joint mounting pad for superior strength and clean appearance
• 4130 CrMo cross shafts, CNC machined and zinc plated for durability
• Precision rod ends allow for arm length adjustment to fine-tune suspension geometry
• Premium tall ball joints installed (0.9-inch taller than stock)
• Travel limiting bolt compatible for drag racing applications
• Polyurethane bump stops included
• Direct bolt-in compatibility with factory or UMI lower A-arms and factory spindles

Important Fitment Notes: The 4056-3 upper A-arm is designed primarily for lowered vehicles. Not recommended for cargo coil or above-stock height applications, as the bump stop may contact the cross brace. Works best with tall ball joints and factory height spindles.

What's Included: Upper A-arms with installed ball joints, polyurethane bump stops, recommended alignment specifications, and detailed installation instructions. Hardware kit (Part #4003) sold separately and includes 7/16-14 Grade 8 bolts, washers, and nylock nuts.
