Spohn Performance 634B Features:

Our tubular adjustable rear upper control arms for the 1971-1996 GM 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.
Our tubular adjustable rear UCAs are constructed from 1.25 in. x 0.095 in. wall DOM tubing with CNC laser cut and formed 1/4 in. thick steel mounting brackets and are 100% TIG welded to handle the most severe abuse.
The adjustability feature allows for setting the pinion angle. Our right hand and left hand threaded CNC machined 4140 chrome moly double male adjuster allows for easy on-car adjustments, no need to unmount the control arm to make adjustments!
Powder coated for a brilliant and durable finish.
