FAQ
Will these rings fit my truck?
Yes—if you have a 2003–2007 Ford 6.0L Power Stroke (Super Duty, Excursion, or E-Series listed above) and a standard-bore block.
Are the rings pre-lapped?
Yes. They’re pre-lapped to seat quickly and reduce break-in time.
How many pistons does one set cover?
One set services the entire engine (8 pistons).
Do I need to check end gap?
Always measure and file-fit to specification for your exact bore and intended use.
What if my cylinders are overbored?
Use the correct oversize set (e.g., 41940.010 / S41940.020 / 41940.030 / S41940.040) to match your machinist’s final bore size.
