UMI Performance 3656-B Upper Control Arm for GM Rear Suspension

The UMI Performance 3656-B is a heavy-duty upper control arm designed to dramatically improve the handling and traction performance of GM vehicles with rear suspension systems. Engineered as a direct bolt-on replacement for weak factory stamped steel arms, this premium control arm eliminates bushing deflection and wheel hop while enhancing cornering ability and track consistency.

Construction Features:

• 1.750-inch x 0.120-inch DOM (Drawn Over Mandrel) mild steel tubing for superior strength
• CNC-machined bushing holders for precise fitment and alignment
• TIG welded construction throughout for maximum durability
• Greaseable Energy Suspension polyurethane bushings included
• Durable powder coat finish in brilliant black

Performance Benefits:

• Eliminates bushing deflection that causes traction loss
• Minimizes wheel hop during hard acceleration
• Improves cornering stability and handling precision
• Enhances track consistency for drag racing applications
• Polyurethane bushings provide better ride quality than OEM rubber

This control arm is sold individually. Please verify your vehicle's configuration before ordering, as six-cylinder and most small-block GM vehicles use a 3-link rear suspension (one upper control arm), while big-block vehicles use a 4-link setup (two upper control arms). Ideal for street performance, drag racing, and restoration projects.
