Some Advantages of Using Titanium Connecting Rods

  • Higher critical g Load = higher RPM for longer durations.
  • Less stress on cylinder walls, crankshaft and bearings due to less rotating weight from crank pin to wrist pin.
  • Reduction of connecting rod weight allows faster acceleration rates.
  • Titanium has a lower thermal expansion rate than steel, and much less than aluminum, which allows the engine builder to hold closer tolerances in the engine.
  • Titanium retains its strength at higher temperatures.
  • Balancing time is usually reduced due to lighter bob-weights and less heavy metal installations.
