Product Details

Features

  • 35 chromoly studs improve main cap retention over factory main bolts
  • 12-point nuts with 3-step 80 ft-lb spec for accurate, consistent torque-down

  • Built for towing, boosted, and high-horsepower bottom-end reliability

Description

Strengthen the bottom end of your Ford 7.3L Godzilla with this Pro Series main stud kit. Factory main bolts can become a limiting factor in high-performance or heavy-load applications — upgrading to studs provides more consistent clamping force and improved main cap retention, helping reduce cap movement and maintain proper crankshaft alignment under stress.

Manufactured from 35 chromoly steel with a black finish, these 12-point studs are built to handle increased cylinder pressure, RPM, and load, while allowing for more accurate torque application and better load distribution than traditional bolts. Recommended for high-load, towing, boosted, or high-horsepower applications.

Installation follows a 3-step torque sequence up to 80 ft-lbs with lube (30 → 60 → 80).
