{"product_id":"umi-performance-3657-b","title":"UMI Performance 65-66 GM B-Body Adjustable Upper Control\/Trailing Arm","description":"\u003cp\u003eUMI  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 65-66 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.\u003c\/p\u003e\u003cp\u003eGenuine UMI Performance.
