These tubular control arms are designed for coil-over, the spring pocket is replaced with a laser cut 3/16" plate and re-enforced with 1/8" tabs. Since the shock T-bar is supporting the load rather than the spring switching to this lower arm ensures strength and durability. These arms are fully assembled with low friction ball joints, and a unique zero bind sway bar end links. The arms have polyurethane bushings which are lube able and offer better performance than stock rubber. These arms are TIG and MIG welded, gig fitted, and powder coated black to ensure proper fitment, strength, and durability.
