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
