Part# 674

These adjustable rear upper control arms for the 1971-1976 GM B-Body Impala, Caprice, etc. 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 of the ends are fitted with grease fittings for easy lubrication of the fluted polyurethane bushings.

These adjustable rear upper control arms are constructed from 1.25″ x .095″ wall DOM tubing and CNC laser cut and formed 1/4″ steel mounting brackets for maximum strength and durability.

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 adjuster allows for easy on-the-car adjustments, no need to unmount the control arm to make adjustments!

They’re available powder coated in your choice of bright red or gloss black for a brilliant and durable finish.
