Step Up Your Axle Game With Proven Strength

When you’re pushing your RAM 2500 or 3500 to work harder, tow heavier, or crawl through tougher terrain, your factory axle can become a weak link. That’s where the Yukon YAW43004 4340 Chromoly Right Front Inner Axle steps in. Built for strength and serious durability, this axle shaft is crafted from high-tensile 4340 chromoly steel to take abuse that stock components simply can't handle. Whether you're putting power to the ground on the trail or hauling a heavy load down the highway, this axle gives you confidence with every mile. It’s not just stronger, it’s smarter, with better materials and superior heat-treating to reduce wear over time. Yukon designed it specifically for the Chrysler 9.25-inch front differential, so fitment is dialed in for 2010-2013 RAM HD trucks. If you're building for reliability and long-term performance, this is one upgrade that pays off the first time you hit the gas.

Built To Handle Torque Where It Matters Most

The Yukon YAW43004 is a right-hand front inner axle designed for 2010-2013 RAM 2500 and 3500 models running the Chrysler 9.25-inch front differential. Measuring 38.1 inches in length, this shaft features 33 cold roll formed splines for added strength and precise gear engagement. It’s constructed from 4340 chromoly steel, a high-tensile alloy known for its excellent fatigue resistance in high-load applications. Yukon enhances that strength even further with induction coil heat treating, which helps the shaft handle repeated torque cycles without cracking or warping. It’s designed to work with the 1555 Series U-joint, offering solid compatibility and dependable joint strength under stress. This axle is built to outperform factory shafts, especially in off-road, towing, and heavy-use environments. For drivers demanding more from their drivetrain, Yukon delivers a solution that’s as tough as the truck it was made for.
