Upper Seat Belt Bar for Shoulder Harness

The Upper Seat Belt Bar for Shoulder Harness (ALL98135) by ALLSTAR PERFORMANCE is an essential structural component for any serious performance vehicle, race car, or high-performance street build that requires professional-grade safety restraint systems. This bar serves as the critical mounting point for multi-point shoulder harness assemblies, enabling drivers to upgrade from factory three-point belts to competition-spec five or six-point harnesses. Whether you're building a dedicated track car, an off-road buggy, or a street machine destined for drag racing, this upper anchor point is non-negotiable for proper harness geometry and driver safety.

Manufactured from heavy-duty steel with a robust design, the upper seat belt bar is engineered to handle the dynamic loads imposed during hard acceleration, braking, and cornering. The bar's 21-inch length provides multiple mounting locations, allowing builders to customize the exact angle and positioning of shoulder harness straps for optimal driver restraint and comfort. Its compact 8 x 1-inch profile enables straightforward bolt-on installation into most roll cage assemblies or structural frame reinforcements without interfering with door operation or interior packaging. The 2.4-pound weight keeps unsprung mass minimal, and the galvanized or painted finish resists corrosion—critical for vehicles exposed to track environments, salt, or moisture.

This upper seat belt bar is ideal for fabricators, race teams, and enthusiasts installing aftermarket harness systems in dedicated race cars, street rods, kit cars, and performance rebuilds. Installation requires welding or bolt-mounting to an existing roll bar or frame structure—professional-level work that ensures load paths are engineered correctly. Compatibility depends on your specific harness manufacturer's specifications and your vehicle's interior layout, so verify clearance and anchor points before ordering. Paired with quality lap and shoulder belts, this bar completes a professional safety system that keeps drivers secure under extreme conditions.
