Sprint Torsion Bar LFRR 1000 Rate 30in

The SWAY-A-WAY Sprint Torsion Bar LFRR 1000 Rate 30in is a precision tubular torsion bar engineered for sprint car suspension tuning. This left front/right rear application delivers a 1000 lb/in spring rate over its 30-inch length, giving drivers the axle control needed for competitive off-road and short-track racing. The chromoly construction with red powder coat finish provides both durability and corrosion resistance in demanding racing environments where suspension stiffness directly impacts lap times and driver feedback.

Specifications confirm this bar's purpose-built design: a 1.0-inch outer diameter tubular body with 1-1/8-inch 48-pitch spline interface ensures reliable connection to sprint car frame mounts while the 30-inch working length matches OEM and aftermarket mounting points. The 1000 lb/in rate balances wheel articulation with chassis stability—stiffer than entry-level setups but not so rigid that it sacrifices compliance on uneven terrain. Chromoly material provides the strength-to-weight ratio necessary for high-frequency suspension movement without deflection, and the red powder coating resists salt spray and moisture that corrode bare steel during transport and outdoor storage.

This torsion bar is purpose-built for sprint car competitors and off-road racers who require tunable suspension geometry. Positioning it at the left front and right rear allows drivers to dial in cross-platform stiffness independently, adjusting handling balance without chassis modifications. At 4.3 lbs, the weight penalty is negligible in a racing application where suspension response directly affects competitiveness. Buyers upgrading suspension systems or replacing worn bars should verify spline compatibility and mounting orientation before installation.
