Oval Racing

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

Torsion Bars should be installed so that they always twist in the same direction.
The bars retain a memory of the direction they are twisting.
If they are twisted in the opposite direction, the spring rate will be compromised.
This can create a situation where the torsion bar fractures and fails.
For this reason its always a good idea to mark the torsion bars.
This will ensure they are used in the correct corners of the car.
