Ring and Pinion Gears


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.
 
Gearing
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.
 We’ve tested our genuine Spicer axle gearing against the gearing of our competitors. See The Difference!
 
Genuine Spicer Gearing Outperforms Knock-offs by up to 280%

 
Demand the durability and reliability only Spicer parts can provide.
 
To prove the exceptional performance of our genuine Spicer gearing, we conducted aggressive dynamometer tests against our competitors. The result? Our gearing had nearly three times longer life. Here’s why:
 
Superior quality steel is blended to the rigorous specifications our research indicates, providing the strength needed to take the loads on the gears
