SPC Performance adjustable upper control arms are loaded with features and are designed, engineered, tested, and assembled in Colorado.
Centering the tire in the wheel well improves suspension travel, handling, and tire wear for maximum clearance needed for oversized tires.
Equipped with maintenance-free ball joints and free-pivoting xAxis sealed flex joints in bonded rubber sleeves, they correct alignment angles and restore factory ride quality.
A forged steel design provides strength and durability for demanding environments.
SPC adjustable control arms have improved clearance to navigate around the spring bucket and offer a full 80° of articulation in the ball joint, more than any other offering available.
When trucks are lifted, caster and camber angles are affected, which can lead to poor handling characteristics such as ‘wandering’.
Built-in positive caster in SPC control arms restores alignment angles and drivability for lifted vehicles.
The patented ball joint design positions the tire correctly in the wheel well, and additional adjustment in the OE lower arms can maximize placement for oversized tires to avoid fender trimming.
If replacement lower adjustment cams are needed, see part #25430.
