Description

The Yukon Chromoly Outer Front Axle is a high-performance upgrade for Dana 30 differentials, offering enhanced durability and reliability. Constructed from heavy-duty 4340 chromoly, this axle is engineered to withstand demanding off-road conditions. Key features include 32 splines for a secure connection and a 6.3-inch length, making it a direct-fit replacement for the outer front axle. It is designed to utilize the 5-760X Series u-joint, ensuring compatibility with standard setups. Yukon high-performance axles are built using superior production methods, including cold-rolled splines and induction coil heat treating.
