Application: 1977-1996 GM B-Body: Impala & Caprice

Note: These upper control arms have a 3/4" extended length to properly center the wheel in the wheel well. Must be used with extended length rear lower control arms (click here).

Our adjustable rear upper control arms for the 1977-1996 B-Body cars outperform the flexible, stamped steel arms and soft rubber bushings that come from the factory.

Eliminate wheel hop and increase traction with an easy bolt on installation. All ends are fitted with grease fittings for easy lubrication of the fluted polyurethane bushings.

The adjustability feature allows for setting the pinion angle. Our right hand and left hand threaded silver zinc plated CNC machined 4140 chrome moly double male stud adjuster allows for easy on-car adjustments, no need to unmount the control arm to make adjustments!

Available powder coated in your choice of the above colors for a brilliant and durable finish.
