Product Description

The Yukon YA WFF30-36.5 is a high-strength 4340 chrome-moly full-float rear axle shaft designed for Dana 60 differentials with 30 splines. Built to replace or upgrade OEM shafts, this cut-to-fit axle covers a length range of 34"-36.5"--ideal for custom suspensions, lifted trucks, or axle swaps.

Yukon's manufacturing process includes cold-rolled spline formation and induction-coil heat treating, ensuring exceptional fatigue resistance and strength. The full-float design supports heavier loads and larger off-road tires, while retaining compatibility with the standard 8x3.96" Dana 60 bolt pattern. Each shaft is backed by Yukon's limited lifetime warranty, making it a reliable and durable choice for performance builds.
