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

Part #: 3662-R

UMI Performance offers one of the only on-car adjustable control arms for the rear of the GM B-Body vehicle. This rear upper control arm for the 67-70 GM B-Body is an excellent solution when looking to replace the worn out factory set-up. Our rear upper control arms are a direct replacement for the factory arms and are designed to minimize wheel hop, improve cornering and help track consistency. This control arm is on-car adjustable and allows easy pinion angle adjustments. Adjustments are made while the control arm stays attached to the vehicle. Competitor designs require you to remove the control arm from the vehicle to adjust. Adjustment can also be used to eliminate the use of shims during installation. Adjusting the control arm is as easy as loosening two jam nuts and turning 4140 Heat Treated Chrome-Moly Adjuster that utilizes left and right hand threads.

UMI's 3662 rear upper control arm is a direct replacement that reduces wheel hop, improves cornering, and boosts track consistency. Easy on-car pinion angle adjustments with greaseable bushings, TIG welds, and a 4140 Chrome-Moly adjuster.
