Left Rear Torsion Arm Black Sprint Car

The Triple X Race Components Left Rear Torsion Arm Black Sprint Car (SC-SU-0117BLK) is a precision-engineered rear suspension component designed for competitive sprint car racing. This single-piece aluminum torsion arm delivers the stiffness and reliability required for high-speed turns and aggressive load transfers on oval tracks, enabling drivers to dial in consistent handling across multiple heat races and feature events.

Manufactured from lightweight aluminum and finished in black anodized coating, this rear driver-side arm measures 17.4 inches in length and weighs just 2.58 pounds—critical factors in sprint car setup where unsprung weight reduction directly improves acceleration response and suspension articulation. The anodized finish provides corrosion resistance essential for maintaining dimensional accuracy across multiple seasons of competition. All necessary mounting hardware is included, eliminating the need for separate fastener sourcing and ensuring compatibility with Triple X's modular suspension architecture.

Sprint car racers standardize on Triple X components because the brand's precision machining tolerances allow seamless integration into existing chassis setups without modification. This left rear torsion arm replaces worn or damaged units while maintaining the factory geometry your suspension tuning depends on. Whether rebuilding after a hard impact, maintaining a competitive baseline, or assembling a fresh car, this arm delivers the repeatability that separates consistent competitors from those chasing variables across multiple race weekends.

Triple X Race Components is recognized throughout the sprint car community for comprehensive rear suspension solutions that accommodate both traditional and adjustable setups. This single rear torsion arm pairs seamlessly with OEM and aftermarket suspension geometries, making it a practical choice for both professional operations and dedicated weekend racers looking to maintain consistent handling characteristics.
