The single upper control arm is responsible for maintaining pinion angle and preventing axle counter-rotation. This "3 link" style suspension is ideal for autocross and road race applications as it allows the most articulation possible with a solid axle. For drag racing, however, the single, centered link becomes a weak point as the arm is only one inch thick in the middle and made from light gauge, stamped steel. Our upper control arm is made from 3/16" CNC formed plate, TIG welded and gusseted completely around the bushing. They are available with polyurethane bushings or spherical bearings. All BMR parts now come in Black Hammertone color. Red will be an additional 20.00 per part number.
