The 188/220 Camshaft is designed for Cummins 12v engines from 1989-2018, delivering improved all-around performance. This camshaft is especially effective for larger single turbo setups or compounds, making it an ideal choice for high-performance enthusiasts. It is perfect for weekend warriors, drag strip racers, and stock class pulling competitors.

For "drop-in" installation on a 12v engine, the engine must have no more than .020″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline. If the engine does not meet the minimum piston-to-valve clearance requirements, using an oversized head gasket or cutting valve reliefs can resolve clearance issues. Although considered a drop-in cam, always check clearances to ensure proper fitment.

Applications

• Ideal for all-around performance
• Suitable for larger single or compound turbo setups
• Perfect for weekend warriors, drag strip enthusiasts, and stock class pulling
• Engineered for Cummins 12v engines

Break-in Instructions
To ensure proper break-in and avoid issues, follow these steps:

1. Apply a liberal amount of high-quality assembly lube to the camshaft.
2. Do not start the engine without verifying oil pressure.
3. Prime the oil pump and oil filter thoroughly, especially for new engines.
4. After break-in, change the oil and filter.
5. Disconnect the fuel system and spin the engine using the starter until oil pressure is visible or oil is flowing from the rocker arms.
6. Avoid running the starter for more than 10 seconds at a time.
7. Once oil pressure is confirmed, run the engine for five minutes at 1200-1500 RPM, then shut it down.
8. Adjust the valves once the break-in process is complete.
9. If you need to re-torque or "hot-torque" the head, do so before adjusting the valves, as this will change the valve lash setting.
