UMI Performance's 12-bolt swap control arms are designed to bolt a 1978-1987 GM A-Body 10-Bolt or 12-Bolt rear end into a 1978-1987 GM El Camino; this includes El Camino, El Camino, El Camino, El Camino, Grand National, El Camino and El Camino. These upper control arms are built at the correct angle to attach to the El Camino chassis as well as the A-Body rear end ears. These upper control arms are a must any time this swap is being completed. Using the factory control arms will cause drastic rear end bind and incorrect driveline angle, this leads to traction lose, vibrations and unsafe handling. These control arms are supplied adjustable for easy on car adjustability to set correct pinion angle and allow adjustment for installation if needed. Adjustments are made using an aircraft quality 4140 chrome moly heat treated adjuster and UMI spherical Roto-Joints. The Roto-Joint allows rear end free movement when high handling, auto cross or road race is a concern but also works excellent as a drag race item by eliminating rear end bind. Upper control arms feature TIG welded construction, 4140 chrome moly tube adaptors to insure thread durability and brilliant powder coat.Features:On-car adjustableMounting plate CNC machined from 0.250 inch thick mild steel4140 heat treated chrome moly adjuster4140 chrome moly threaded tube adaptorsSpherical Roto-Joints installedShipped fully assembled and ready to installUses OEM hardwareBrilliant and durable powder coat finish
