BNR engines billet gearboxes are designed for racing and high performance applications.

The gear box cases are CNC machined from billet aircraft alloy to ensure precision accuracy.

All the shafts are splined, precision ground and heat treated for strength and reliability.

The gears are CNC hobb machined, splined, shot peened and heat treated for better tooth contact.

Gear box drive (prop release) coupling complies with APBA standards for ultimate safety.
