Spicer Life Series® and Spicer 10® Series U-Joints: Tested and Proven.
Dana engineers subject Spicer parts to stringent testing, and that’s your assurance of quality that leaves the competitors in the dust. Nowhere is that more apparent than with our Spicer SPL universal joints.
We performed fatigue testing on Spicer Life Series and Spicer 10 Series u-joints and measured them against the competition. The results were astonishing.
Commercial Vehicle U-joints Outperform the Competition
Spicer 10® Series u-joints lasted twice as long as the nearest competitor. Spicer Life Series® u-joints’ performance was literally off the charts. After one million cycles, Spicer Life Series universal joints had still not failed.
Light Vehicle U-joints Outperform the Competition
Spicer 1810 Series u-joints—not just better. 5x better than the competition in fatigue testing. Spicer Life Series® u-joints outperformed the competition in fatigue testing by more than 2.1!
Spicer® Ring and Pinion Gearing: Where Process Meets Performance.
Spicer® is a Dana brand name—it's the brand name Dana uses for their axle and driveshaft products. Spicer® ring and pinion gearing is the genuine gearing in all Dana manufactured axles, and is manufactured with a special grade of steel, and machined and heat-treated to precision, so you can count on matched sets for optimal set-up and mating of the gears.
Like all Spicer® products, we put our ring and pinion gears to the test to see how they measure up against the competition. 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!
- Ensures optimal hardness in Spicer’s top quality steel
- Creates dispersion throughout the part
- Holds back-face runout to very tight tolerances
- Cuts gearing to precision spacing between gear teeth
- Ensures continuous indexing so teeth are constantly mated
- Significantly reduces noise, vibration, and harshness
- Shoots controlled microbeads of steel at the root of the gear tooth, adding compressive residual stresses into the root of the tooth
- Doubles the fatigue life of the gear
- Removes tool cutter marks from tooth contact area
- Reduces noise and heat
- Produces a better contact pattern
