Engineered for Longer Life and a Smoother Ride in Your Axle.Ring & Pinion Animation

Dana design, engineering, testing, and manufacturing processes all work together in Spicer® ring and pinion gearing to ensure performance that non-genuine parts simply cannot deliver. Spicer gearing offers the easiest possible set-up, a quieter ride and strength that can’t be beaten for genuine Dana axles.

PROBLEM
“I need ring and pinion gearing that avoids setup challenges and excess noise, and that delivers unmatched strength and lifespan.”

SOLUTION
The surface treatment on Spicer® ring and pinion gearing creates a quiet gear, and highly sophisticated manufacturing processes mean that Spicer gears generally set up with a proper pattern on the first attempt, and that lifespan can be up to double that of non-genuine parts.

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!
