SPC Performance Upper Control Arms (UCAs) are engineered to increase suspension down travel and improve vehicle handling and tire wear by allowing for better alignment. They feature a heavy duty, high-misalignment, constant preload, sealed and greaseable ball joint and proprietary bushings for a long service life.
SPC UCAs are designed specifically for each vehicle to correct alignment angles and allow for larger tires while maintaining factory ride quality. The arms are either fully forged, or a combination of forged sertions with DOM tubing for a clean look, high strength, and maximum durability, even under that harshest off-road driving conditions.
SPC 36mm heavy-duty ball joints are as strong or stronger than a spherical bearing (uniball), spacer, and bolt combination, and allow for 80 degrees of articulation. The arms are built with 1 degree of positive camber and the patented ball joint design offers up to an additional 4 degrees of positive caster and plus or minus 2 degrees of camber adjustability for a perfect alignment.
