Adjustable Upper Control Arms

The adjustable upper control arms by SPC Performance are engineered for serious suspension tuning and alignment correction on street and track vehicles. These components are essential for mechanics and enthusiasts who demand precise camber and caster adjustments beyond factory specifications. Whether you're dialing in a lowered street setup, preparing a road-course competitor, or correcting geometry after a frame-off restoration, adjustable upper control arms unlock the ability to achieve optimal tire contact patch and handling balance that fixed arms simply cannot provide.

SPC Performance's design utilizes precision-manufactured adjustment mechanisms that allow incremental changes in both camber and caster geometry without requiring complete re-fabrication or multiple bushing sets. The robust construction and sealed adjustment hardware resist corrosion and maintain calibration under demanding suspension cycles. The adjustable upper control arms integrate seamlessly with factory mounting points while offering the fine-tuning capability required for performance alignment sheets. This level of adjustability proves invaluable when optimizing for tire wear, steering response, and load transfer characteristics across varying driving conditions and suspension heights.

These adjustable upper control arms benefit drivers running independent double-wishbone or MacPherson strut front suspensions who have modified ride height or geometry beyond stock tolerances. Professional alignment technicians, suspension shops, and DIY builders working on classic restorations or modern performance builds will find the adjustment range essential for correcting bump-steer and achieving zero-scrub geometry. Installation requires standard suspension work procedures and a quality alignment machine for final tuning; compatibility depends on your specific vehicle platform and suspension design, so verify fitment against your chassis before purchase.
