Product Details

Features

  • Fits Ford 7.3L “Godzilla” V8 engines (2020+ Super Duty & swaps)

Description

Strengthen the foundation of your Ford 7.3L engine with the Pro Series Main Stud Kit, engineered to improve bottom-end durability and performance.

The factory main bolts can become a limiting factor in high-performance or heavy-load applications. Upgrading to main studs provides more consistent clamping force and improved main cap retention, helping reduce cap movement and maintain proper crankshaft alignment under stress.

Designed for the modern Ford “Godzilla” 7.3L V8, this kit is ideal for performance builds, towing applications, and high-horsepower setups where reliability is critical. High-performance fastener systems like these are commonly used to enhance engine strength and durability in demanding conditions.

Manufactured from heat-treated high-strength alloy steel, these studs are built to handle increased cylinder pressure, RPM, and load. The stud design also allows for more accurate torque application and better load distribution compared to traditional bolts.

Whether you're building a street truck, race engine, or swap project, this kit delivers the strength needed to keep your bottom end secure.
