UMI Performance 3651-R Upper Control Arm Rear Suspension GM

The UMI Performance 3651-R is a high-performance rear upper control arm designed for GM vehicles with 3-link or 4-link rear suspension systems. This precision-engineered control arm replaces weak factory stamped steel components with robust construction that eliminates wheel hop, improves cornering stability, and enhances track consistency.

Key Features:

• 1.750" x 0.120" DOM (Drawn Over Mandrel) mild steel tubing for superior strength
• CNC-machined bushing holders for precise fitment and alignment
• TIG-welded construction ensures maximum durability
• Greaseable Energy Suspension polyurethane bushings reduce deflection and binding
• Durable powder coat finish protects against corrosion
• Direct bolt-on replacement for OEM control arms
• Also known as "banana arms" due to their curved design

Application Notes:

This control arm is sold individually. Six-cylinder and most small-block equipped GM vehicles typically use a 3-link rear suspension requiring one upper control arm, while big-block vehicles use a 4-link setup requiring two upper control arms. Please verify your vehicle's suspension configuration before ordering.

Performance Benefits:

Stock GM control arms suffer from bushing deflection and weak stamped construction that lead to traction loss and poor handling. The UMI 3651-R eliminates these issues with rigid DOM tubing and low-deflection polyurethane bushings. Ideal for street performance, drag racing, road racing, or restoration projects where improved suspension geometry and reduced wheel hop are priorities.
