Product Description

The **Ford Performance M-4130-M8S GT350 Half Shaft Kit** is a direct replacement and upgrade rear axle shaft set engineered for modern Ford Mustang models. Originally used as the factory half shafts in **Shelby GT350 and GT350R** Mustangs, these shafts feature an increased diameter compared to stock Mustang GT units, offering improved strength and durability under power. The value-priced kit includes both the left and right half shafts required for a full rear-end replacement and is particularly suited for **naturally aspirated cars and mild drivetrain modifications** where stock axles may start to show wear or flex.
