FAQ
Is this the correct side plug for my 2003–2018 Cummins?Yes — PDM-07003 fits common-rail 5.9L (2003–2007) and 6.7L (2007.5–2018) Ram 2500/3500 engines on the side of the block. Always verify your engine year and location before ordering.
How many side freeze plugs are required?The engine uses multiple core plugs in different locations. This listing is sold individually for the side position. Check your engine for quantity needed.
Should I upgrade other plugs at the same time?It’s smart to inspect the rear/back-plate plug and consider a retention plate on higher-RPM builds.
Do I need a coolant bypass?On higher power or towing applications, a rear coolant bypass can help stabilize temps and reduce pressure spikes that stress core plugs.
