UMI Performance 67-70 GM B-Body Adjustable Upper Control/Trailing Arm

When you're working on the rear suspension of your 1967-1970 GM B-Body, especially if you're looking to dial in your pinion angle or combat wheel hop, this adjustable upper control arm from UMI Performance is a solid option. It's designed as a direct replacement for your factory arms, meaning it fits right in without needing modifications. This part is key for improving how your car handles during cornering and helps keep your tracking consistent, whether you're on the street or at the track.

What sets this control arm apart is its on-car adjustability. You can make changes to your pinion angle without having to remove the arm from the vehicle, which saves a lot of time and hassle during setup. It's built with a 4140 heat-treated Chrome-Moly adjuster for strength and durability, and the TIG welded construction ensures a strong, reliable joint. Plus, it comes with greaseable Energy Suspension polyurethane bushings, which help absorb road vibrations and can be easily serviced to keep things moving smoothly.

Keep in mind that some vehicles, particularly big block models, use a 4-link setup with two upper control arms, while six-cylinder and small block cars might have a 3-link setup with just one. This part is sold individually, so be sure to check your specific vehicle's configuration to order the correct number of arms. The durable powder coat finish not only looks good but also helps protect the arm from the elements.
