Description

Designed to fit Dana 30 differentials specifically when an aftermarket locker is installed, this axle ensures reliable performance in challenging conditions. It is the inner front axle for the left-hand side, measuring 18.8 inches in length and featuring 30 splines for secure engagement. Constructed from heavy-duty 4340 chromoly, this axle offers superior strength and durability compared to standard axle materials, resisting bending and breakage under stress. It is designed to work with a 7166 Series u-joint, ensuring compatibility with a common performance standard. The "with aftermarket locker only" technical note highlights a critical fitment requirement for proper function and installation. This axle is intended for enthusiasts who have upgraded their differential with an aftermarket locker, providing a direct replacement or upgrade path for their front axle assembly. Its robust construction and precise specifications aim to restore or enhance the drivetrain's capability and longevity.
