Product Description
The HAMILTON CAMS 07-CC-24V188 CAST 188/220 CAMSHAFT COMBO is a complete valvetrain upgrade package engineered for 1998.5–2018 24-valve Cummins engines. Designed for enthusiasts seeking stronger mid-range power, improved turbocharger response, lower exhaust gas temperatures, and increased performance under load, this proven Hamilton package includes all of the critical components needed for a properly matched camshaft installation.
The 188/220 profile is commonly referred to as Hamilton's "Hot Street" grind and is ideal for street performance, towing with larger turbochargers, drag racing, sled pulling, and high-performance daily-driven applications. Operating efficiently in the 1,700–4,500 RPM range, the camshaft improves airflow and cylinder scavenging while maintaining excellent drivability.
Unlike purchasing individual valvetrain components separately, this combo package includes a matched camshaft, heavy-duty pushrods, 103 lb valve springs, and lifters/tappets to ensure proper valvetrain stability and reliability. Hamilton's proven design helps reduce EGTs by approximately 200–300°F while delivering stronger mid-range acceleration and improved turbo spool-up characteristics.

FAQ
What is the difference between the 178/208 and 188/220 Hamilton combos?
The 178/208 is optimized for towing, efficiency, and low-RPM operation, while the 188/220 is designed for stronger mid-range power, larger turbochargers, and higher-performance applications.
What comes in the 07-CC-24V188 combo kit?
The kit includes the 188/220 camshaft, heavy-duty pushrods, 103 lb valve springs, and new tappets/lifters.
Will this camshaft help lower EGTs?
Yes. Hamilton reports EGT reductions of approximately 200–300°F due to improved airflow and cylinder scavenging.
Is this camshaft good for compound turbo setups?
Absolutely. The 188/220 profile is commonly recommended for larger single turbochargers and compound turbo systems because of its improved airflow and mid-range power characteristics.
Does piston-to-valve clearance need checked?
Yes. Hamilton recommends verifying no more than .018" piston protrusion and at least .038" valve face depth when using a standard head gasket on 24-valve engines.
Is this a good daily driver camshaft?
Yes. While designed for performance applications, many owners successfully run the 188/220 combo on daily-driven trucks that require stronger mid-range power and improved turbo response.
