Titanium Motorsport Car Pins

At Solar’s Western PA plant, titanium anti-roll bar torsion pins were vacuum heat treated for an Indycar racing team.  Solar’s customer is Rayco Machine Company, Indianapolis.  This adjustable suspension component gives the driver the capability to change the rate of the chassis roll on the suspension, thereby, changing the handling of the racecar.

Currently, this component is manufactured using 4340 on other teams.  However, the engineering group of the Indycar race team looked into the titanium pin for its weight reduction properties, but has discovered that it flexes much more in each setting giving the driver a wider range of adjustment.  The good part is that it’s perfectly legal.

Originally the titanium torsion pins heat treatment was assigned for water quenching, but Robert Perez, Motorsports Manager for Rayco, discussed the advantage of high pressure gas quenching for minimized distortion.  The titanium pins were vacuum heat treated and was metallurgically tested by LTI, Hatfield, PA, for tensile strength.
