7.3L Powerstroke Torque Ratings

Jan 22nd 2026

Bolt torque for the 7.3 Powerstroke shouldn’t be a mystery. So we collected everything from Ford’s service manuals and other reputable sources, and listed them all below. Here’s your one-stop shop resource for everything nut and bolt torque-related.

Important Notes:

What is listed below assumes factory original parts and hardware are being used. If you’re using aftermarket parts, always refer to the manufacturer's recommendations.
Always make sure your fasteners and threaded areas (threads cut into the block, front cover, etc) are in good condition. Stripped threads, more often than not, are due to damaged and/or contaminated threads or fasteners.
The info below has been taken from the most official sources we can find, mainly Ford and International service manuals. However, use this info at your own discretion. There's no replacement for common sense.
Inch pounds as well as foot pounds are mentioned. Make sure to use the correct rating.
