1989-2018 Cummins 188/220 Hot Street/Strip Camshaft (Steel) (07-c-188/220S)

This Cam increases midrange power great for moderate competition from idle to 4,500RPM. This Hamilton Cam is a great companion with a 66mm or smaller turbo for low RPM power or with large singles at higher RPM in 24V applications. 

Note: The 1989-1998 Cummins 5.9L 12V will require no more than .025" piston protrusion and at least .055" valve face depth with a standard head gasket. In 1998.5-2002 5.9L Cummins applications, you will require no more than .025" piston protrusion and a minimum of .038" valve face depth with a standard gasket. The 2003-2018 5.9L/6.7L Cummins engines will require .018" piston protrusion and a minimum of .038" valve face depth with a standard gasket. You can still run an oversize head gasket or cut valve reliefs if you do not meet the requirements for the piston to valve clearance. 

Part Number: 07-c-188/220S

• The largest drop in cam
• A great option for moderate competition
• You can still run an oversize head gasket or cut valve reliefs if you do not meet the requirements for the piston to valve clearance. 

• Recommended upgrading pushrods to prevent loss in valve lift or retarded timing.
• Recommended to upgrade valve springs to prevent valve float and improve performance.
• Required to run steel tappets and machine the engine block for cam bushings
• Must verify clearances even though this camshaft is considered a drop-in replacement.
