Perfect for street, race, higher horsepower and V8 applications-where the additional strength is really needed!


  • Precision machined from aircraft grade billet aluminum to exacting standards for perfect fit and function
  • Silicone bronze shift rail bushings, which are replaceable
  • Input shaft bearing oilier
  • Lightest weight possible, only 4.25 lbs.
