Description

The Interstate-McBee M-3957492 is a rear seal housing gasket designed for 2003-2018 Dodge Ram trucks equipped with 5.9L or 6.7L Cummins engines. This gasket restores a proper seal between the rear main seal carrier and the engine block, effectively preventing oil seepage.

Manufactured to OE-equivalent specifications, this gasket features durable materials that offer heat and oil resistance. It is ideal for service when replacing the rear main seal or resealing the housing, offering a direct replacement with OE geometry for a reliable seal at the rear cover/housing.
