Axles. U-Joints. Gearing. The Difference Is Unmistakable.
Don’t be fooled. There is a difference when it comes to drivetrain components. Products backed by Dana start with precision engineering, and the parts they manufacture are put through rigorous testing. It’s all done to ensure the products you purchase for your vehicle meet the same standards we deliver to OE manufacturers around the world.
Axles: Dana 44 vs. What's the Diff?
Most aftermarket axle manufacturers use the Dana name to describe the model/application/ ring gear size of their aftermarket axles, but the Dana Diamond is your guarantee of getting genuine quality, Dana-manufactured parts straight from the original source—DANA.
Quality engineering and materials, coupled with precision manufacturing and testing, make the difference.

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.
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.
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.
- 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
