FAQ

Does this fit my 2003–2007 5.9L?

Yes, this set targets the 2003–2007 common-rail 5.9L Cummins. It does not fit 2007.5+ 6.7L models.

Is the rear main seal included?

Most lower sets include front and rear crank seals, but contents can vary. Check the product images/contents list or contact us to confirm.

Do I need additional sealant?
