Unlock More Torque When It Matters Most

If you're towing heavy loads or climbing steep grades, you know how important it is to have power right where you need it. The Hamilton Cams 07-C-178/208 Stage 1 Towing Camshaft delivers that low-end grunt that makes all the difference, especially when the weight behind you starts to push back. Designed specifically for street-driven Cummins trucks from 1989 to 2018, this camshaft wakes up your 5.9L or 6.7L by helping the turbo spool much sooner and boosting airflow at lower RPMs. That means faster throttle response, better drivability, and noticeable gains in torque without sacrificing daily comfort or reliability. Whether you’re hauling equipment for work or pulling a trailer through high-altitude mountain passes, this cam keeps your powerband right where you want it. It's also a smart upgrade if you're running stock or mildly modified turbos and injectors. With proven horsepower gains and real-world performance improvements, this cam isn't just a swap, it's an upgrade you’ll feel every time you hit the throttle.

Engine Efficiency Starts With The Right Camshaft

At the core of the 07-C-178/208 camshaft’s design is its short duration and wide lobe separation angle, which work together to reduce valve overlap and cut down on in-cylinder EGR. This is a big win for trucks running stock turbochargers with restrictive turbine housings, where drive pressure tends to exceed boost. In that setup, this cam improves airflow efficiency and allows the engine to breathe more cleanly, especially under load. Tested with an 80hp injector and 62mm turbo setup, it delivered an impressive 40 horsepower gain at just 1700 RPM. That early boost in power translates into quicker spool-up times and better midrange performance, ideal for heavier trucks or those that live in high-altitude environments. While it excels in towing and economy builds, it's also well suited for common rail trucks with larger single turbos or ported cylinder heads. The camshaft makes these setups more streetable by improving throttle control and smoothing out part-throttle driving. When paired with the proper intake centerline, installation is straightforward and well worth the results.
