If you are building a race engine or high performance street engine  Billet Gears become mandatory.
Factory Sintered Oil Pump Gears perform quite well even in medium to high horsepower applications, however, the more time you spend in the high rpm range, particularly if you are hitting the limiter the more likely they are to fail.
Factory Gears are extremely hard for durability purposes, unfortunately they are also very brittle.
Consistent high load & high RPM causes fractures to occur in the gear set. The solution to this is a Billet Gear Set, All the hardness of a Factory Gear Set without the Brittleness.
Billet gears are machined from high-strength materials with tighter tolerances than the standard sintered gears, reducing the risk of gear failure at sustained high RPM and oil pressures. This enhanced strength helps maintain consistent oil delivery to critical engine components, improving lubrication, reducing wear, and providing greater confidence in engine performance during demanding race conditions.
