UMI Performance 3056-1-B Adjustable Upper A-Arm with Standard Ball Joints Black

The UMI Performance 3056-1-B is a race-engineered adjustable upper A-arm built for serious performance driving. Designed to excel in Pro-Touring, road race, autocross, and high-performance street applications, this upper control arm delivers the precision geometry and adjustment range that competitive drivers demand.

At the core of the design are race-quality rod ends that provide shim-free camber and caster adjustment with exceptionally smooth suspension travel. The relocated ball joint pad increases caster and improves steering feel and stability, while a shortened cross-shaft-to-ball-joint distance further refines front-end geometry. The arm is a direct bolt-in replacement compatible with factory or UMI lower A-arms and tall spindles.

Construction Highlights:

• 0.120" wall thickness, 1.250" diameter DOM tubing with machine-guided bends for correct geometry and material strength
• TIG welded for superior strength and clean aesthetics
• Laser-cut ball joint mounting pad for precision fitment
• 4130 chromoly cross shafts — CNC machined and zinc plated
• High-quality Tiger Dry Lac powder coat finish for long-lasting durability
• Polyurethane bump stops included
