RF Torsion Arm Angle Broached Black

The RF Torsion Arm Angle Broached Black from King Racing Products (MPN 1135) is a precision-engineered front suspension component designed for sprint car racing applications. This angle broached torsion arm delivers the rigidity and adjustability required for high-performance motorsport, where suspension tuning directly impacts handling, stability, and lap times. The black anodized aluminum construction resists corrosion while maintaining the lightweight properties essential for competitive racing.

Measuring 18.95 inches in length with a compact cross-section of 2.5 x 1.15 inches and weighing just 1.66 lbs, this torsion arm is engineered for the passenger-side front position. The angle broach design allows for precise attachment and alignment angles critical to sprint car geometry, while the anodized finish provides durability against fuel, oil, and track debris exposure. Hardware is included to facilitate straightforward installation and replacement. The aluminum material balances strength with the weight savings that competitive sprint car builds demand.

This component is essential for sprint car builders, restoration teams, and serious racers maintaining or upgrading front-end suspension systems. Whether replacing a damaged arm, fine-tuning chassis geometry, or building a race-ready suspension package, the RF Torsion Arm Angle Broached Black provides the precision and durability expected in competitive racing environments. King Racing Products components are recognized in the motorsport community for their exacting specifications and compatibility with standard sprint car platforms.

Sprint car suspension design requires components that maintain consistent geometry under extreme load and lateral forces. Torsion arms control wheel travel and camber changes throughout suspension articulation, making their angle, length, and material composition critical to chassis balance. The angle broach feature on this arm allows racers to achieve the precise mounting angles needed for their specific track setup and driving style.
