Industrial DB2829-4879 Diesel Engine Piston Assembly

Industrial DB2829-4879 Diesel Engine Piston Assembly is a Stanadyne DB2 injection-pump piston designed for GM 6.2L and 6.5L diesel engines. This replacement piston is part of the injection pump’s internal metering assembly and works with the DB2-style pump to regulate fuel delivery and timing during engine operation. The part is commonly used in service and rebuild applications for Stanadyne-equipped 6.2L/6.5L powerplants, including those found in older GM/Detroit Diesel installations. It is sold as a piston assembly rather than a full pump, intended to restore proper pump function within the fuel-injection system.
