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 identificationTORSION BAR BENEFITS
