Building Dana 80 Heavy Duty Off-Road Roller Axles – Crane Axle

When it comes to building a bombproof axle platform, the Dana 80 sits in a league of its own. In our latest behind-the-scenes shop video, we walk you through how we take a brand-new Dana 80 raw center section and transform it into a fully assembled Heavy Duty Roller Axle—ready for your next off-road build. From pressing in 4” x .500 wall tubes to installing our heat-treated 2.5-ton rear spindles, Magnum Inner C’s, Crane Outer Knuckles, and lightweight 2.5-ton aluminum wheel hubs, this setup is built for anyone who demands extreme strength and reliability. With the ability to run 2” and 47-spline axle shafts, these Dana 80 platforms are perfect for hardcore crawlers, bouncers, and custom builds that need maximum durability.

Roller Axles give builders and shops a smart, affordable way to start their projects without the upfront cost of gears, lockers, and axle shafts. Fabricators can mock up suspension, steering, and chassis components right away—then return later to finish with the internals when the build is ready. Many shops also love using our Roller Axles as a clean starting point for gear installs and custom axle shaft packages, letting them add their own value for customers while still relying on a proven Crane Axle foundation.

In the video, we take you step-by-step through cutting and prepping tubes, pressing housings, assembling knuckles and hubs, and setting up the rear spindles. It’s a complete look at how we build the same Heavy Duty Roller Axles you can order for your own project.
