Yukon Gear Steel Spool For Dana 80 w/ 35 Spline Axles / 4.10+

If you're building a dedicated off-road rig or a drag car that needs maximum traction, a Yukon Gear & Axle steel spool for your Dana 80 differential is a solid choice. This spool replaces your factory differential carrier, forcing both axles to turn at the same speed, all the time. This means you get 100 percent of your available power to both wheels, no matter the terrain or situation. It’s designed specifically for Dana 80 axles that use 35-spline axles and are set up with a 4.10 or numerically lower gear ratio.

Yukon makes these spools from strong 8620 steel, then heat-treats them to ensure they can handle the abuse of serious performance applications. Because it locks both wheels together, this type of differential isn't recommended for vehicles that see regular street driving, as it can make turning difficult and put extra stress on the drivetrain components during normal road use. This is a component for vehicles that are primarily used off-road or on the drag strip.

Installation involves removing your existing differential carrier and installing the spool in its place, making it a straightforward conversion for a dedicated performance differential. This spool fits a range of heavy-duty trucks and vans, including many Chevrolet C3500, Dodge Ram 2500, and Ford F-350 models from the 1990s and early 2000s. Always refer to the manufacturer's installation instructions for specific details on setting up your differential.
