Adjustability is one of the most important aspects when tuning your street car's suspension. That’s why we have developed the Ultimate adjustable upper control arms for the rear of your GM vehicle. We used only the best materials and components to create our "Ultimate Arms." Weak areas have been replaced with aircraft-quality 4140 chrome moly steel, featuring TIG welded construction. The upper control arm mounting points use CNC machined 0.250" mild steel, 4140 chrome moly tube adapters, and a high-strength 4140 chrome moly heat-treated 1.000" solid adjuster.
For ease of adjustment, our Ultimate Arms provide on-car adjustability. You can easily make pinion angle adjustments in your garage or at the track by simply turning the adjuster while the control arms are on the car. Pinion angle adjustments are essential for improving track 60-foot times, enhancing traction, and reducing wheel hop. Our QA1 Teflon-lined spherical rod end design allows for a bind-free operation, making it an excellent upgrade for both track and autocross vehicles.
