Radius Rod Sprint Car 21in x 1-1/8in

The TRIPLE X RACE COMPONENTS Radius Rod Sprint Car 21in x 1-1/8in (SC-SU-0107) is a precision-engineered suspension component purpose-built for competitive sprint car racing. This 21-inch polished aluminum radius rod features a 1.125-inch outer diameter and 5/8-18 female threads, delivering the structural rigidity and geometric accuracy required in high-performance sprint car suspension systems. Radius rods are critical load-bearing members that control wheel movement and maintain consistent suspension geometry through aggressive cornering and acceleration cycles.

The 1.125-inch OD specification is industry-standard for sprint car applications, balancing strength-to-weight ratio essential for vehicles operating at competitive speeds. The polished aluminum construction delivers a 0.91 lb weight per rod—critical in a category where total suspension mass directly impacts acceleration and handling response. The 5/8-18 female threaded end accommodates standard sprint car chassis connection points, ensuring compatibility with TRIPLE X and other manufacturers' suspension systems. The 21-inch length positions this component for frame configurations common in winged and non-winged sprint racing.

Sprint car racers, fabricators, and suspension specialists rely on TRIPLE X radius rods to maintain consistent lateral wheel control and predictable chassis dynamics. Whether rebuilding a suspension after impact damage, upgrading worn components, or constructing a new chassis assembly, this radius rod delivers the dimensional precision and material quality expected in competitive racing environments. Stock-car fabricators and independent race shops specify TRIPLE X components for their proven performance record and reliable fitment across sprint car platforms.

TRIPLE X Race Components has established a strong reputation within sprint racing circles for producing frame and suspension components that meet the exacting tolerances demanded by sanctioning bodies and competitive teams. The radius rod is sold individually, allowing repair or upgrade of single components without requiring complete suspension replacement. For sprint car racers prioritizing suspension reliability and dimensional accuracy, this TRIPLE X radius rod is an essential inventory item.
