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 1 5/8" x .120 wall DOM tube and is MIG welded. We use the largest adjuster in the industry, 1-1/8", for a bulletproof combination.

New for 2011 we have incorporated an application-specific, dual-durometer bushing. This 4-piece bushing utilizes a high-durometer center bushing to resist deflection under heavy loading and two outer, low-durometer bushings to allow articulation during handling. This makes the control arm equally at home on the drag strip, street, or road course.
