The TRZ Motorsports Pro Upper Control Arms (Part #320-PRO-UPPERS) are engineered for C2/C3 Corvette owners looking for a high-strength, high-precision upgrade over factory suspension components. Built from TIG-welded chrome-moly tubing, these Pro-series arms deliver maximum rigidity, reduced deflection, and improved suspension geometry for both street and drag applications.
Each kit includes two upper control arms assembled with ball joints, premium chrome-moly rod-ends, and travel limiter bolts to precisely control front suspension extension. These arms are designed as direct replacements for OEM components and install with no modifications required.
