FAQ
Is .040" the same as 1.00 mm?Yes—.040" equates to approximately 1.00 mm oversize.
Is this ring set sold per cylinder or for the whole engine?
This listing covers one piston. For a full 6-cylinder 5.9L, order six ring sets.
Will this fit all 1989–2007 5.9L Cummins?
Not universally. Ring packs vary by piston design. This set is used on specific B/ISB 5.9L applications. For many 1989–2002 builds, the .040" pack is 3802423. Please verify by ESN/piston P/N.
Do I need to file-fit the rings?
Follow the Cummins service manual. Check end gap in-bore and file-fit if required to meet spec for your application.
