Yukon Blank 4340 Replacement Axle For Dana 30 & Dana 44 36.25in Long Not Splined 1.346in Diameter

If you're working on a Dana 30 or Dana 44 differential, this blank 4340 chromoly axle from Yukon Gear & Axle is a solid replacement part. It's designed to be 36.25 inches long with a 1.346-inch diameter, and it comes un-splined, meaning you'll need to machine the splines to match your specific application. This is common when building custom axle setups or replacing a damaged inner axle shaft where the original spline count or style might be different.

Yukon builds these axles using high-tensile strength 4340 chromoly steel, which is known for its strength and durability. They use production methods that include cold-roll formed splines, and the axles are heat-treated using an induction coil process. This combination helps create a strong, reliable axle that can handle the demands of off-road use or heavy-duty applications. The blank design gives you the flexibility to customize the spline end for a precise fit in your differential.

This axle is intended for use with a 5-760X U-joint size. Because it's a blank axle, it's crucial to ensure you have the proper machining capabilities or a trusted shop to cut the splines to your exact specifications before installation.
