OE-Quality Gear Sets for Cars, Trucks, and SUVs.

Spicer® Finishes First in Fatigue Tests

The Test: During fatigue tests, each gear is installed in a production axle attached to a dyno. The axle runs on the dyno until the gear fractures. The high-load test simulates a loaded vehicle going uphill or carrying extra capacity such as a trailer. The-low load test simulates everyday driving at an accelerated rate.

The Result: Under high-load conditions, Spicer ring and pinion gears lasted an average of 121,080 cycles—nearly three times as many cycles as the closest competitor. And under low-load conditions, Spicer ring and pinion gears performed more than twice as many cycles as the competition!
