Description

The Yukon Chromoly Rear Axle Kit by Yukon Gear and Axle is engineered for robustness and reliability in Dana 44 differentials. This kit is specifically designed for Jeep JK Non-Rubicon models and features 30 splines with a total length of 32 inches, making it suitable for either the left or right side of the axle. The construction utilizes heavy-duty 4340 chromoly, providing superior strength and longevity for demanding off-road applications. Its 5 x 5.0” bolt pattern ensures direct compatibility with the specified Jeep JK configurations. This axle kit offers a significant upgrade over stock components, providing enhanced durability for off-road use, towing, or other high-stress driving conditions. The 4340 chromoly material is known for its exceptional strength-to-weight ratio and resistance to fatigue, ensuring consistent performance even under extreme loads. The product details confirm its suitability for Dana 44 differentials and its precise measurements and spline count.
