Remember: Non-genuine replacement parts are usually not manufactured to the same standards, which can cost you more in the long run. 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. That's because our superior quality steel is blended to rigorous specifications, providing the strength needed to take the loads on the gears.

Experience the difference that genuine OE quality can make for your off-highway vehicles.


Processes and Testing Deliver Superior Results.
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.
