UMI's adjustable front upper A-arm for GM A-body cars is built for Pro-Touring, road race and autocross duties, offering shim-free camber and caster adjustment via race-quality rod ends. The arm relocates the ball joint pad to increase caster and shorten cross-shaft distance for improved steering feel and stability. Manufactured in the USA from 1.250" DOM tubing with CNC-machined components, it ships with installation instructions and recommended alignment specs.
