SPC Performance Adjustable Front Upper Control Arms (Sold as a Pair)
Designed, engineered, tested, and assembled in Colorado, SPC Performance’s adjustable upper control arms are built for lifted trucks that need more travel, better handling, and proper alignment. These arms help center your tire in the wheel well for maximum clearance with oversized tires—while improving suspension travel, drivability, and tire wear.
Now equipped with maintenance-free ball joints and xAxis™ sealed flex joints housed in bonded rubber sleeves, SPC arms deliver the alignment correction you need while helping restore a smooth, factory-like ride. Their forged steel construction provides the strength and durability demanded by off-road and harsh driving environments.
