Overview
Made in the U.S.A.
Built to survive.
A universal, adjustable brace linking the driver’s seat back to the harness bar or main hoop. Prevents seat collapse under rear-impact loads — a requirement in many sanctioned classes and a habit of drivers who plan to keep racing. Available in multiple sizes to fit different harness bar diameters and seat positions.
Every Auto Power structure is fabricated to order in our San Diego shop. Lead time is typically 3–4 weeks. Custom variants are quoted individually.
