Good To Know

Q: Are cylinder head bolts included in this upper engine head gasket set for Cummins? A: No, head bolts are typically sold separately and should be replaced as they are torque-to-yield fasteners.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
