Radius Rod Sprint Car 18-1/2in x 1-1/8in

The Triple X Race Components Radius Rod Sprint Car 18-1/2in x 1-1/8in (SKU: TXRSC-SU-0100) is a precision suspension component engineered for competitive sprint car racing. This polished aluminum suspension tube measures 18.5 inches in length with a 1.125-inch outer diameter and features 5/8-18 inch female threading at both ends, providing a direct bolt-in solution for radius rod applications on sprint car chassis.

The polished aluminum construction offers a critical balance for sprint car suspension geometry. Aluminum reduces unsprung weight compared to steel alternatives, which improves suspension responsiveness and reduces chassis stress during cornering and acceleration. The 1.125-inch OD tube diameter is a standard specification in sprint car suspension design, where precise geometry is essential for maintaining front-end control on dirt and asphalt oval tracks. The 5/8-18 female threads accept standard rod ends, allowing straightforward assembly and fine-tuning of ride height and suspension angles. Weighing just 0.83 lbs, this component minimizes added mass while maintaining the rigidity required for consistent handling.

Sprint car racers, fabricators, and suspension specialists rely on radius rods as critical linkage elements that control rear axle movement and lateral weight transfer. This Triple X component is designed for builders who demand OEM-equivalent precision and durability in high-speed oval racing environments. Whether you're replacing a worn rod, building a new suspension geometry package, or upgrading an existing chassis, this radius rod delivers the dimensional accuracy and material quality expected in competitive motorsports.

Triple X Race Components has established a reputation in the sprint car market for manufacturing suspension components that meet the exacting standards of circle-track competitors. The polished finish not only resists corrosion in outdoor storage and salt-air environments but also simplifies visual inspection of the tube for any signs of wear or damage during pre-race checks.
