Torsion Arm Micro Sprint 4-3/8in Right Rear

The Torsion Arm Micro Sprint 4-3/8in Right Rear is a precision rear suspension component engineered for competitive Micro Sprint racing vehicles. This passenger-side torsion arm is essential for maintaining proper suspension geometry, load distribution, and handling dynamics during high-speed cornering and acceleration. Built for serious racers who demand reliability and consistency lap after lap, this component plays a critical role in translating driver input into predictable chassis behavior on dirt and asphalt tracks.

Manufactured from durable aluminum and finished in black anodize, the Torsion Arm Micro Sprint features a 7/8-inch by 48-spline connection that ensures secure mounting and repeatable positioning. The 4-3/8-inch configuration paired with the arm's compact yet rigid design optimizes weight transfer characteristics while minimizing unsprung mass. Aluminum construction reduces overall vehicle weight without compromising strength, while the anodized finish provides corrosion resistance and durability in demanding racing environments. The precision engineering allows for accurate suspension tuning, enabling teams to dial in the exact front-to-rear balance required for their specific track and driving style.

This right rear torsion arm is ideal for Micro Sprint racers building or maintaining competitive platforms who require OEM-quality components from trusted manufacturers like Joe's Racing Products. Installation requires proper alignment and torque specifications to ensure suspension geometry remains within design parameters. Teams should verify compatibility with their specific chassis configuration before ordering, as suspension geometry directly affects overall vehicle performance. Whether you're replacing a worn component or upgrading an existing setup, this torsion arm delivers the precision and durability expected in competitive racing.
