Adjustable Upper Control Arms

The Adjustable Upper Control Arms by SPC Performance are designed for serious suspension tuning and alignment correction on a variety of vehicles, including both street and track applications. These components are essential for mechanics and automotive enthusiasts who require precise camber and caster adjustments that exceed factory specifications.

SPC Performance's adjustable upper control arms feature precision-manufactured adjustment mechanisms that allow for incremental changes in camber and caster geometry. This design eliminates the need for complete re-fabrication or multiple bushing sets, ensuring robust construction and sealed adjustment hardware that resists corrosion and maintains calibration under demanding conditions.

These adjustable upper control arms are particularly beneficial for drivers with independent double-wishbone or MacPherson strut front suspensions who have modified ride height or geometry beyond stock tolerances. The ability to fine-tune alignment settings is invaluable for optimizing tire wear, steering response, and load transfer characteristics across various driving conditions.
