Dana Spicer Drive Axle Assembly

Dana Spicer Drive Axle Assemblies: OEM Engineering Meets Real-World Performance

When it comes to complete drive axle assemblies, few names carry the weight of Dana Spicer. As a division of Dana Incorporated — a global leader in drivetrain and e-Propulsion systems — the Spicer brand has spent more than a century earning its reputation as the benchmark for axle quality, strength, and durability. A drive axle assembly is the critical link between your vehicle's drivetrain and its wheels: engine torque flows through the driveshaft, enters the axle housing, and is distributed to the axle shafts through internal gearing, ultimately putting power to the ground. Choosing a complete, engineered assembly — rather than piecing together individual components — ensures every element is matched, tested, and ready to work together from day one.

What Sets Dana Spicer Apart in Drive Axle Assemblies

Dana Spicer's drive axle assemblies are not simply aftermarket rebuilds. Genuine Spicer products are manufactured to the same high standards as original equipment — because in most cases, they are OEM parts. This means buyers are getting the same engineering tolerances, material specifications, and quality controls that vehicle manufacturers rely on, in a direct-fit package.

The flagship of Dana Spicer's complete axle assembly lineup is the Dana Crate Axle Program, which brings genuine Dana 44™, Dana 60™, Ultimate Dana 44™, and Ultimate Dana 60™ assemblies to the performance and off-road market. Every crate axle ships brand new — housing, gears, bearings, and axle shafts all manufactured to exacting standards and ready for installation.

• Ultimate Dana 44™ Assemblies: Built for serious off-road enthusiasts, these assemblies feature thicker axle tubes for improved rigidity, chromoly axle shafts for optimal strength, Spicer Life Series (SPL) 1350 u-joints with triple lip seals, genuine Spicer gearing, and optimized pinion angles for lifted vehicles. Increased gross axle weight ratings (GAWR) accommodate the added demands of bumpers, winches, and larger tires.
• Ultimate Dana 60™ Assemblies: Dana's most heavy-duty offering for off-road builds, featuring Spicer 70 u-joints, 35-spline nickel chromoly steel axle shafts, high-strength brackets, a nodular steel differential cover, and Spicer 10-inch ring and pinion gearing — engineered for lifted vehicles running larger tires.
• AdvanTEK® Technology: Dana's AdvanTEK axle platform, available in complete assembly configurations, represents the brand's next generation of high-efficiency axle engineering for modern trucks and SUVs.

Patented Technology and Long-Term Reliability

What makes Dana Spicer drive axle assemblies stand out beyond their product names is the underlying technology. Dana's exclusive combination of patented technologies and designs ensures long service life, reduced maintenance, and more durable axle products. Features like an engineered axle breather design allow unrestricted airflow — a maintenance-free detail that protects the assembly over the long haul. Whether you're building a trail-ready Jeep Wrangler, maintaining a fleet truck, or replacing a worn factory axle, Dana Spicer's complete assemblies provide a foundation you can trust.
