The Hamilton Cams 07-H-001-STG3 Stage 3 Performance Cylinder Head greatly improves the airflow on your 1989-1998 Dodge 5.9L Cummins. Competition or street ready, this CNC ported head is a big performance upgrade right out of the box.
All of this translates to increased power, reduced turbo lag, and lower exhaust gas temps throughout your desired rpm band. A thicker deck and casting is used to reduce heat warping and is also more resistant to cracking compared to a factory style cylinder head. The factory style intake shelf offers more flow to cylinder 1 and 6 versus a factory casting by reducing restrictions in the ports.
This Stage 3 Cylinder Head comes loaded with 165 conical springs, 1.850” intake valves and a 1.750” exhaust valves, upgraded tool steel retainers and valve stem seals.
