Description

The Yukon Chromoly Inner Front Axle is engineered for durability and performance in GM 8.5-inch differentials. Constructed from heavy-duty 4340 chromoly, this axle is built to withstand demanding off-road and heavy-use conditions. This specific inner front axle is designed for the left-hand side of the vehicle and features 30 splines, ensuring a secure and robust connection. It measures 35.46 inches in length and is compatible with the 5-760X series u-joint, providing a direct fit for many GM applications. Key specifications include its 30-spline count and its 35.46-inch measurement, making it a precise component for differential repairs or upgrades. The heavy-duty 4340 chromoly construction signifies enhanced strength and longevity over standard axles.
