HAMILTON CAMS TOWING CAMSHAFT 07-C-178/208 | 1998.5-2007 & 2013-2018 Cummins 5.9L/6.7L

The Hamilton Cams 07-C-178/208 Camshaft is engineered for maximum efficiency and improved low-RPM performance in Dodge and Ram Cummins applications. Designed for towing, daily driving, and moderate street driving, this camshaft delivers quicker turbo spool-up, improved drivability, and increased engine efficiency.

Featuring short duration and a wide lobe separation angle, this camshaft minimizes valve overlap to improve low-end response and fuel economy while helping reduce exhaust gas temperatures.

Key Benefits:

• Improves low-RPM airflow and turbo response
• Excellent towing and daily driving characteristics
• Helps reduce EGTs by 200–300 degrees
• Optimized for efficiency and street-driven trucks
• Ideal for larger single turbo setups

Features:

• RPM range: Idle – 4000 RPM
• Duration @ .050": 178° intake / 208° exhaust
• Wide lobe separation angle for minimal overlap
• Improved low-end torque and drivability
• Drilled and tapped for bolt-on cam gear retainer
• Compatible with larger valve and ported cylinder head setups

Installation Notes:

• Install with intake centerline from 1997–1999 specifications
• Zinc additive required (not included)
• Proper piston-to-valve clearance must be verified during installation

Clearance Requirements:
