The Yukon 4340 30 Spline Inner Axle with Aftermarket Locker (Right) is engineered specifically for Jeep Wrangler models from 2007 to 2017 equipped with either the 3.8L V6 or 3.6L V6 engines. Designed for off-road enthusiasts and performance drivers, this axle delivers exceptional strength and reliability under demanding conditions. It is an ideal upgrade for those seeking enhanced drivetrain durability and improved traction through the integration of an aftermarket locker.
Built to withstand the rigors of trail use and heavy-duty applications, this inner axle ensures consistent power transfer and reduces the risk of failure during high-torque situations. Whether you are upgrading your factory components or building a custom off-road rig, this Yukon axle provides a dependable foundation for your drivetrain.
This Yukon inner axle combines advanced manufacturing techniques and premium materials to deliver superior performance and longevity. Key features include:
The Yukon 4340 inner axle is crafted from premium 4340 chromoly steel, known for its exceptional strength-to-weight ratio and fatigue resistance. This material choice ensures the axle can endure the stresses of off-road driving and high-torque scenarios without bending or breaking. The cold roll forming process used on the splines enhances their structural integrity, providing a tighter spline fit that reduces wear and drivetrain slop.
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 shaft that resists abrasion and impact damage. The combination of these manufacturing techniques produces a component that meets or exceeds OEM standards for strength and durability.
This inner axle is designed as a direct replacement for the right side axle shaft on 2007–2011 Jeep Wrangler models with the 3.8L V6 engine and 2012–2017 models with the 3.6L V6 engine. Installation requires no modifications when paired with compatible aftermarket lockers and factory components, making it a straightforward upgrade for experienced mechanics and off-road enthusiasts alike.
Proper installation ensures optimal engagement with the differential and smooth drivetrain operation. It is recommended to verify compatibility with your specific locker model and to follow all torque specifications during assembly to maintain reliability and performance.
This Yukon inner axle is ideal for Jeep Wrangler owners looking to upgrade their drivetrain for enhanced off-road capability and durability. It suits enthusiasts who frequently tackle challenging terrain, require reliable traction solutions, or are building high-performance Jeep Wranglers with aftermarket lockers. It is also an excellent choice for those seeking a robust replacement axle that outperforms factory components in strength and longevity.
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!
