Adjustable Front Upper Control Arms

Designed, engineered, tested, and assembled in Colorado, the SPC Performance adjustable upper control arms are built to enhance the suspension and handling of your Lexus LX 470 or Toyota Land Cruiser 100 Series. These control arms improve suspension travel, tire wear, and wheel alignment while centering the tire in the wheel well for maximum clearance needed for oversized tires. Crafted from forged steel with chromoly tube construction, they deliver maximum strength and durability for demanding off-road environments. The arms feature a new ball joint with a 25% larger stud cross-section for superior strength, coated with E-Nickel for corrosion resistance, and capable of 80° of articulation. The adjustable range of these arms, combined with OEM adjusters, allows precise correction of camber and caster angles, restoring factory ride quality and handling, especially on lifted vehicles where alignment issues are common. The patented ball joint design offers more adjustability than any other arm on the market, with a one-piece polymer race ball joint that ensures quiet operation, reduced wear, and extended lifespan. The sealed flex joints in bonded rubber bushings facilitate extended suspension travel and improve noise, vibration, and harshness (NVH) characteristics. These control arms are designed with additional caster provision for lifted vehicles, ensuring proper alignment and drivability. They are sold as pairs and are compatible with knuckle gusset kits, providing a versatile solution for off-road enthusiasts and truck owners seeking reliable performance upgrades.
