Detroit DD15 Head Gasket Replacement Kit

The cylinder head gasket provides critical sealing between the DD15 cylinder head and engine block. During a head removal or major top-end repair, replacing the associated gaskets and sealing components helps restore proper sealing around combustion, oil, intake, exhaust, and coolant passages.

The PAI 631395 kit is designed to provide many of the gaskets needed during a DD15 cylinder-head service in one complete package, reducing the need to source individual upper-engine gaskets separately.

PAI 631395 vs. PAI 631375

PAI 631375 is the DD15 cylinder head gasket set containing the primary head gasket and associated head-gasket components.

PAI 631395 is a larger complete head-gasket kit that includes the 631375 head gasket set plus additional upper-engine sealing components such as the valve cover, intake manifold, turbo, exhaust manifold, charge air cooler, and related gaskets.

If the repair requires more than the cylinder head gasket set itself, the 631395 provides a broader gasket package for the DD15 top-end service.

DD15 Fitment Verification

Important: Detroit DD15 engines have multiple gasket configurations and running changes. Always verify the engine serial number (ESN), VIN, engine configuration, and existing gasket/OEM part numbers before ordering.

PAI 631395 is cataloged specifically for the Detroit Diesel DD15. Do not assume that every DD15 engine uses the same head gasket configuration without confirming the engine identification.

PAI 631395 Warranty

PAI 631395 is listed with a 2-year unlimited-mileage PAI warranty. Warranty coverage should be confirmed for the exact product at the time of purchase.
