    Gun-Drilled Torsion Bars for Sprint Cars

    Strange Oval torsion bars have been winning races since 2008. We’re one of racings best kept secrets.

    • Repeatable ride height without adjustment
    • Holds rate for extended period of time – we’ve run them for 30+ races
    • Unparalleled consistency, even after wrecks
    • Seamless and smooth spline fit – leave your mallet at home
    • Our manufacturing method differs from anything on the market
    • Critical hardness and yield numbers are better than anything on the market
    • Aircraft quality chrome vanadium steel offers superior yield strength, fatigue properties, and impact toughness
    • Vertical rack heat treating controls distortion
    • CNC hobbed serration splines for precise and consistent fit
    • Generous transition fillet radii essential to reduction of stress risers
    • Lightweight gun-drilled design
    • Additional attention directed to non-aggressive machining to impart a minimum amount of residual tensile stress
    • Shot peening provides increased torsional and bending fatigue life with the application of residual compressive stress
    • Laser etched part number on torsion bar O.D. gives the relationship to a common solid bar’s equivalent rate
    • Common solid bar number of equivalent rate also engraved onto the end of strange torsion bar for easy identification
