Because of its light weight and superior strength, titanium is useful for reducing reciprocating mass in high stress applications. In sport car racing, this translates to greater speed with lower energy consumption. A benefit for passenger vehicles is greater fuel economy without sacrificing performance.
Titanium components such as rocker arms, cams, crank shafts, connecting rods, wheels, turbine impellers and valves are commonly available through aftermarket parts suppliers. Titanium connecting rods are standard on select OEM models.
