Spicer® Finishes First in Fatigue Tests
The Test: Each gear is installed in a production axle, which runs on a dyno until the gear fractures. Both high-load and low-load simulation tests are performed.
The Result: Under low-load conditions, Spicer ring and pinion gears performed more than twice as many cycles as the competition. Under high-load conditions, Spicer ring and pinion gears lasted nearly three times as many cycles as the closest competitor!
