Radius Rod Sprint Car 19in x 1-1/8in Black

The Radius Rod Sprint Car 19in x 1-1/8in Black from Triple X Race Components is a precision-engineered suspension control rod designed for serious sprint car competitors and oval track racers who demand predictable handling and repeatable setup. Radius rods are critical suspension geometry components that control the rear axle housing position relative to the frame, directly influencing chassis dynamics, weight transfer, and cornering stability.

This particular 19-inch configuration fits popular sprint car platforms and is sized to work within tight packaging constraints while maintaining structural rigidity through acceleration, deceleration, and high-speed cornering. Triple X manufactures this radius rod with high-strength steel tubing designed to withstand the extreme loads and vibration cycles inherent to dirt track racing. The 1-1/8-inch diameter tubular profile provides an optimal balance of lateral stiffness and longitudinal compliance, allowing the rear axle to move vertically through suspension travel while resisting unwanted lateral deflection.

Weighing just 0.8 lbs, the component minimizes unsprung mass—a critical factor in sprint car setup where every ounce affects suspension response and tire loading consistency. The precision end-eye geometry ensures repeatable mount-point geometry lap after lap, eliminating play that can lead to unpredictable handling changes. This radius rod is compatible with popular 410 and 360 winged sprint car platforms, making it an essential upgrade for racers looking to enhance their vehicle's performance.
