The Radius Rod Sprint Car 19in x 1-1/8in Black is a precision aluminum suspension component engineered for high-performance sprint car racing applications. This 1.125-inch outer diameter tube serves as a critical load-bearing element in sprint car chassis geometry, maintaining precise suspension geometry and steering response under extreme cornering forces. At 19 inches long with 5/8-18 female threads on each end, this radius rod connects the chassis frame to the front spindle assembly, directly influencing handling balance and tire wear characteristics.
Constructed from aluminum and finished in black anodize, this component resists corrosion while minimizing unsprung weight—a critical consideration in sprint car suspension tuning where every ounce affects acceleration, braking response, and directional stability. The threaded design allows for adjustable length configurations, enabling crew chiefs to fine-tune suspension geometry to track conditions and tire compounds. Weighing just 0.8 lbs, the radius rod contributes minimal mass while providing the rigidity required for consistent front-end handling during high-speed turns and rapid direction changes.
This component is designed for serious sprint car competitors and fabricators building or maintaining front suspension systems. Whether tuning for micro-sprint, non-wing, or outlaw sprint car classes, this radius rod delivers the structural integrity and precision fit needed for reliable performance. Triple X chassis components are recognized within the sprint car racing community for dimensional accuracy and consistent fit, making this rod a direct replacement or upgrade option for original equipment configurations.
Sprint car suspension geometry demands precision-manufactured components. The 19-inch length and 1.125-inch diameter are industry-standard dimensions for front-end radius rod applications, compatible with common sprint car frame designs and spindle assemblies. Anodized aluminum provides superior corrosion resistance compared to bare aluminum or mild steel alternatives, extending component life through multiple race seasons.
