Tubular Torsion Bar 30in 1.050in Dia

The STRANGE OVAL Tubular Torsion Bar 30in 1.050in Dia is a gun-drilled, tubular suspension component engineered for sprint car and high-performance racing applications. This 30-inch torsion bar combines shot-peened steel construction with precision spline geometry to deliver consistent roll stiffness control across aggressive track conditions. The 1.050-inch outer diameter and 1-1/8-48 inch spline configuration are designed to interface with purpose-built suspension systems that demand repeatable, tunable handling characteristics.

Gun-drilling through the bar's length reduces unsprung weight while maintaining torsional rigidity—a critical balance in sprint car suspension where precise load transfer directly affects lap times and driver feedback. Shot peening the steel surfaces introduces compressive residual stress in the outer fibers, significantly improving fatigue resistance under the cyclic loading conditions typical of racing. The natural (uncoated) steel finish allows for easy customization and painting to match team specifications. At 4.97 lbs, this torsion bar fits lightweight, competition-focused suspension geometries where every ounce contributes to performance.

Sprint car builders and suspension tuners select STRANGE OVAL components for their dimensional accuracy and metallurgical consistency. This torsion bar serves drivers working with established suspension designs that specify 1.050-inch diameter and 30-inch length geometry. It is not a street suspension component; it is purpose-built for oval track racing where suspension tuning translates directly to competitive advantage. Proper installation requires alignment with the vehicle's existing pickup points and spline interface—consulting the chassis manufacturer's technical documentation is essential before assembly.
