Discover the exceptional on-car adjustable control arms from UMI Performance, specifically engineered for the rear of GM B-Body vehicles. Our Rear Upper Control Arm for the 58-64 GM B-Body stands out as a top-tier solution when seeking to replace the factory setup. Designed as a direct replacement for factory arms, these control arms minimize wheel hop, enhance cornering, and contribute to improved track consistency.
What sets our control arms apart is their on-car adjustability, allowing for easy pinion angle adjustments without detaching the arm from the vehicle. Unlike competitor designs that require removal for adjustments, our system simplifies the process. You can make adjustments while the control arm remains attached, eliminating the need for shims during installation. The adjustment process involves loosening two jam nuts and turning the 4140 Heat Treated Chrome-Moly Adjuster, which utilizes left and right hand threads for added convenience.
Equipped with Energy Suspension grease-able bushings, these upper control arms are TIG welded and feature a 4140 heat-treated Chrome-Moly adjuster. Affectionately known as "Banana Arms," these arms redefine performance and versatility.
Please note that this item is sold individually, so it's essential to verify whether your vehicle requires one or two upper control arms. Six-cylinder and most small block vehicles typically feature a 3-link rear suspension, while big block vehicles utilize a 4-link setup.
