Top Wing Flat w/Super Side Boards In Tube

The Hepfner Racing Products Top Wing Flat with Super Side Boards in Tube is a complete sprint car aerodynamic kit designed to maximize downforce and stability on high-speed oval tracks. This aluminum assembly combines a flat-profile top wing with extended super side boards, engineered to optimize airflow dynamics during competitive racing. The kit arrives in a protective 76-inch tube and weighs 40 lbs, making it manageable for transport between events while maintaining the structural integrity required for demanding racing conditions.

Constructed from aluminum with a natural finish, this wing system features dimpled surfaces on the top wing that enhance aerodynamic efficiency by reducing drag and improving pressure distribution across the wing profile. The super side boards extend the effective wing area, providing lateral stability through high-speed turns while maintaining predictable handling characteristics. The flat-wing design offers a balance between downforce generation and reduced drag compared to curved profiles, making it a popular choice for tracks where speed and cornering consistency are equally important. The complete kit arrives ready for installation, eliminating the need to source components separately.

This package is built for competitive sprint car drivers who prioritize proven aerodynamic performance and repeatability across multiple race events. Whether you're running weekly sanctioned races or traveling to invitational events, the Hepfner Racing Products reputation for precision manufacturing ensures consistent performance. The aluminum construction provides strength while keeping overall weight low—a critical consideration in sprint car racing where every pound affects acceleration and fuel efficiency. Serious competitors choose Hepfner products because the engineering translates directly to lap times and reduced setup tuning between events.
