Ring and pinion set

Ring and Pinion Kits Built to Standards for Quality and Performance.

All "Boying" ring gear and pinion sets are designed and tested to meet original equipment specifications. They're built to the latest designs, which include:

Premium heat treat processes

Optimum tooth profiles

High-grade steel for maximum durability

Our ring gear and pinion sets are designed and manufactured in matched sets for optimal performance and reduced wear. That means that the parts you purchase will meet the standards that your original equipment manufacturers trust.

 From quality materials, and then they are subjected to computer-controlled processes and rigorous testing.

Superior metallurgy: Ensures more consistent, higher quality product.

Hobbed and shaved gearing: Provides optimal mating to minimize stress and maximize life.

Precision heat-treating and shot-peening: Delivers consistent quality, enhanced life by reducing residual stress and exceptional durability.
