FAQ
Will this fit both 5.9L and 6.7L Cummins?Yes. It is intended for 2003–2007 5.9L and 2007.5–2018 6.7L Cummins rear freeze plug back plate applications.
Does this come with an O-ring?No. PDM-08207 is the without O-ring version. If your build calls for an O-ringed plug, browse our Cummins Freeze Plugs & Back Plates.
Do I need additional gaskets or sealant?We recommend having fresh rear main seals and any associated housing gaskets on hand, plus a sealant approved by your service manual. See Gaskets & Seals for Cummins.
Is this compatible with high-horsepower builds?Yes—proper installation and cooling system integrity are key. Many performance builds use solid back plate plugs; verify your spec first.
What if my engine plate uses a different plug style?Some plates require an O-ringed plug. If unsure, compare your existing part or contact us and check our Cummins Freeze Plug options.
