Yukon Gear Steel Spool For Dana 44 w/ 30 Spline Axles / 3.92+

If you're building a dedicated off-road rig or a drag car that needs maximum traction, a Yukon Gear & Axle steel spool is a solid option. This spool replaces your differential carrier assembly in Dana 44 axles that use 30-spline axles and are set up with a 3.92 or numerically lower gear ratio. It's designed to provide 100% lockup, meaning both rear wheels will always turn at the same speed, ensuring you get power to both tires, no matter the terrain.

Yukon makes these spools from strong 8620 steel and then heat-treats them for added durability. This makes them well-suited for the harsh conditions found off-road or the stresses of drag racing. Because it locks the differential full-time, it's not recommended for vehicles driven regularly on public roads, as it can make turning more difficult and cause tire scrub. This spool fits a wide range of vehicles, including many Chevrolet K10 pickups and Dodge W100 models from the 1960s through the 1990s.
