Description

The USA Standard Gear ZA W38816 is a 4340 Chrome Moly outer stub axle engineered for robust performance in demanding drivetrain applications. Constructed from heavy-duty 4340 chromoly material, this axle offers superior strength and durability compared to standard OEM components. Designed for a precise fit, the ZA W38816 features 19 splines and a length of 9.72 inches from the spline end to the center of the U-joint bore. It is specifically designed to accept a 5-760X series universal joint, ensuring compatibility with common driveline setups. This axle is intended for use with Dana 44 front differentials. Vehicle fitment includes the Ford F-150 (1976-1979), Ford Bronco (1978-1979), and Ford F-250 (1979). It is also compatible with Jeep Wagoneer models equipped with drum brakes.
