Product Description
The ATS 318-910-3104 E4OD / 4R100 Billet Forward Clutch Drum is a heavy-duty transmission upgrade for 1989-2003 Ford applications running the E4OD or 4R100 automatic transmission behind the 7.3L Power Stroke. Built from billet steel for substantially improved strength over stock components, this forward clutch drum is designed to handle the abuse of high-horsepower builds, towing, and hard-use transmission applications.
In performance transmission builds, the forward clutch drum is a critical hard part that must withstand repeated clutch engagement, elevated line pressure, and increased torque load. The ATS billet construction helps reduce the risk of failure in demanding conditions, making it a smart upgrade for builders looking to improve reliability and support serious power.
This component is especially well-suited for performance E4OD and 4R100 builds where stock drums become a weak point. ATS publicly describes this billet forward clutch drum as recommended for applications over 1,000 horsepower, making it an ideal choice for extreme street, towing, and competition-oriented Power Stroke transmission builds.
