Balance the handling of your classic Mustang with QA1’s 0.875” (7/8”) tubular rear sway bar, engineered for 1964–1970 models. Purpose built for QA1 rear coilover conversions and designed to match the performance of QA1’s front sway bars and suspension systems, this rear bar reduces body roll, improves traction, and helps your Mustang corner with confidence.
