The Yukon Rear 4340 Chrome-Moly Axle is engineered for Dodge Ram 2500 and 3500 models from 2003 through 2018, covering a wide range of engines including the 5.7L Hemi, 5.9L Diesel, 6.4L 392, and 6.7L Diesel variants. Designed for high-performance applications, this axle delivers exceptional strength and durability to handle demanding driving conditions and heavy loads. Whether you’re upgrading for off-road adventures, towing, or enhancing your truck’s overall drivetrain reliability, this axle provides a robust solution that meets rigorous standards.
Built to withstand the stresses of high torque and heavy-duty use, the Yukon axle is ideal for enthusiasts and professionals seeking a dependable rear axle upgrade that maintains factory fitment and performance.
This axle combines advanced materials and manufacturing techniques to ensure superior performance and longevity. Key features include:
The Yukon rear axle is crafted from premium 4340 chrome-moly steel, a material known for its exceptional tensile strength and fatigue resistance. This alloy is commonly used in high-performance automotive components due to its ability to withstand extreme stress and impact. The axle’s splines are cold roll formed, a process that enhances the metal’s grain structure and increases spline strength and durability.
Additionally, the axle undergoes an advanced induction coil heat treating process. This treatment hardens the surface while maintaining a tough core, resulting in an axle that resists wear and deformation under heavy loads and high torque conditions. The combination of these manufacturing techniques ensures a product that delivers long-lasting performance in demanding environments.
The Yukon Rear 4340 Chrome-Moly Axle is designed for direct fitment on 2003–2018 Dodge Ram 2500 and 3500 models equipped with 10.5-inch or 11.5-inch rear axle housings. It fits multiple engine configurations including 5.7L Hemi, 5.9L Diesel, 6.4L 392, and 6.7L Diesel engines. Installation typically requires no modifications, allowing for a straightforward replacement or upgrade of the factory axle shafts.
Professional installation is recommended to ensure proper torque specifications and alignment, preserving drivetrain integrity and vehicle safety.
This axle is ideal for Dodge Ram owners who demand enhanced durability and strength from their rear axle components. It suits:
Yukon Gear & Axle supplies hardcore drivetrain components—ring & pinion gears, axles, lockers, and differential upgrades—built for off-road and high-load performance. Trusted by enthusiasts and installers, Yukon focuses on fit, strength, and proven options for re-gearing and reinforcing trucks and 4x4s running bigger tires and tougher terrain.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
