Strength You Can Count On When It Matters Most

When you’re putting your GM HD truck to work, the last thing you want is to second-guess your axle strength. The Yukon YAWGM14T-30-38 Chromoly Axle Shaft is built to handle serious stress, whether you're hauling heavy loads, pushing through trails, or laying down torque with upgraded gears. It’s made from high-strength 4340 chromoly steel, giving it the toughness needed for extreme-duty use. Yukon doesn’t just rely on strong materials either. They use cold roll forming and deep heat treating to maximize durability where it matters most, especially around the bearing and seal areas. This axle is cut-to-length, so it fits applications ranging from 34.8 to 38.8 inches, giving you flexibility without sacrificing precision. It’s made to fit GM 2500HD and 3500HD models from 1999 to 2012, making it a smart upgrade for aging or underbuilt stock axles. If you’re upgrading your differential or just looking for something that won’t quit under pressure, this shaft is a solid choice.

Engineered For Demanding 14 Bolt Applications

The Yukon YAWGM14T-30-38 is a performance-grade axle shaft designed to fit GM’s 10.5 inch 14 bolt and 11.5 inch full-float differentials. It features a 30 spline configuration and a cut-to-length range from 34.8 to 38.8 inches, giving it semi-universal compatibility within the supported range. Manufactured using 4340 chromoly, this axle delivers higher tensile strength than standard materials, making it ideal for high-load, high-stress conditions. Yukon also applies cold roll forming to the splines to enhance fatigue resistance and ensure a longer service life under constant torque. The shaft is finished with advanced induction heat treating, which targets both core strength and surface durability. This combination of production methods makes it a great fit for trucks running oversized tires, performance gears, or heavy towing setups. Designed to exceed OE specs, this axle is a reliable replacement for demanding 1999-2012 Silverado and Sierra 2500HD or 3500HD builds.
