Spohn Performance 626-4130B Features:

Our Del-Sphere pivot jointed 4130N chrome moly tubular adjustable rear upper control arms for the 1964-1967 GM A-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.
The adjustability feature allows for setting the pinion angle. Our right hand and left hand threaded CNC machined 4140 chrome moly male/female double adjuster allows for easy on-car adjustments, no need to unmount the control arm to make adjustments!
Our 4130N chrome moly tubular adjustable rear UCAs are constructed from 1.25 in. x 0.095 in. wall 4130N chrome moly 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.
Powder coated for a brilliant and durable finish.

Del-Sphere Pivot Joints:
The Spohn Performance Del-Sphere pivot joint solves the shortcomings of the factory rubber and aftermarket polyurethane bushings. Our Del-Sphere pivot joint incorporates a spherical ball which is surrounded by Delrin® bushing cups.
Think of the Del-Sphere pivot joint as a Delrin® bushed spherical rod end. The Delrin® bushing cups absorb shock and road noise so you get the quiet and smooth ride of a bushing as well as 22° of rotation! Designed and manufactured exclusively by Spohn Performance, we have taken street suspension performance to the next level.
Our Del-Sphere pivot joint features a one piece forged and heat treated 4130 chrome moly housing, a heat treated and chrome plated chrome moly spherical ball, Delrin® bushing cups, heat treated retainer washers and snap ring, an external grease fitting, and a beautiful silver zinc plated housing finish.
Unlike a spherical rod end, the Del-Sphere pivot joint is 100% rebuildable.
