UMI Performance 2653-1-B Upper Control Arm Set for 1970-1981 GM F-Body

UMI Performance's 2653-1-B upper A-arms are precision-engineered suspension components designed to transform the handling characteristics of 1970-1981 GM F-Body muscle cars. These tubular control arms add 4 degrees of caster to improve steering feel and reduce highway wandering, while the ½" taller ball joint mounting improves camber gain for enhanced cornering performance and lateral grip.

Key Features:

• Direct bolt-in replacement for 1970-1981 Chevrolet Camaro and Pontiac Firebird
• 1.250" DOM (Drawn Over Mandrel) steel tubular construction for strength and weight reduction
• 4140 chrome-moly offset cross shaft provides camber adjustability and exceptional strength
• Greasable UMI-built Delrin bushings ensure smooth motion and precision steering response
• High-quality ball joints pre-installed and ready to install
• Polyurethane pancake-style bump stops for controlled rebound
• Available in gloss black powder coat finish
• 100% designed, manufactured, and tested in Philipsburg, Pennsylvania USA

The offset cross shaft design minimizes the need for alignment shims during installation, making setup easier while allowing precise camber adjustment. The Delrin bushings provide a superior balance between performance and street comfort compared to traditional polyurethane bushings, with less noise and binding. Suitable for both aggressive street driving and competitive racing applications.

Optional hardware kit available separately, including Grade 8 bolts, washers, and lock nuts for professional installation. Sold as a complete upper A-arm set for both sides of the vehicle.
