Ring & Pinion and Gearing That's Off-Highway Tough

Ring & Pinion

All Spicer 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 and the most optimum tooth profiles, plus high-grade steel to achieve maximum durability.


Spicer gearing is manufactured with a special grade of steel, machined and heat-treated to precision, so you can count on optimum set-up and mating of the gears.

The Benefits:

  • 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 and exceptional durability.

Remember: Non-genuine replacement parts are usually not manufactured to the same standards, which can cost you more in the long run. Reduce your downtime and cost with genuine Spicer OE products.
