Hamilton Cams 178/208 Street Cam 89-18 5.9L / 6.7L CumminsThis cam will help to drastically reduce exhaust gas recirculation (EGR) and provide more fresh, cool air for your engine. That means less particulate matter, lower exhaust gas temperatures (EGT's), and better fuel economy! Originally, Hamilton built this cam for 6. 7L Cummins owners looking to create overall efficiency while keeping all of the factory emissions system intact.

This cam will help to drastically reduce exhaust gas recirculation (EGR) and provide more fresh, cool air for your engine. That means less particulate matter, lower exhaust gas temperatures (EGT's), and better fuel economy!

Originally, Hamilton built this cam for 6.7L Cummins owners looking to create overall efficiency while keeping all of the factory emissions system intact. If you have accepted that DPFs are here to stay, but you want to make more power and you don't like wasting fuel to clean out your DPF, this is your cam! And for owners of 5.9L's, after further development, Hamilton learned that this cam also worked extremely well in these models for creating efficiency in moderate street trucks. Due to its short duration and wide lobe separation angle, it also has the least overlap (when intake and exhaust valves are open at the same time) of any of Hamilton's cams, which helps to eliminate in cylinder EGR on engines that have higher drive pressure than boost. This occurrence is usually found on trucks with stock turbos with a restrictive turbine housing.

CAST IRON VS STEEL CAMSHAFT COMPARISON:

When it comes to valvetrain performance and long-term reliability, steel camshafts offer clear advantages over traditional cast iron designs. Steel is significantly stronger and more resistant to cracking, flexing, and wear under high-load conditions, making it ideal for engines running heavier valve springs, higher RPM, increased boost, or elevated cylinder pressures. Unlike cast iron, which can be brittle and more prone to lobe wear or failure in demanding applications, steel maintains its structural integrity and precise lobe shape over time. This added rigidity helps maintain accurate valve timing under stress, improving consistency, efficiency, and overall durability. Whether you’re towing heavy, racing, or building a high-performance daily driver, a steel camshaft provides the strength and longevity needed to protect your investment and keep your engine performing at its best.

If you live at high altitudes, tow heavy, or are looking for the best efficiency possible for highway driving, this cam will be your best friend. And for those running larger turbos on a common rail engine, this cam will aid in low RPM spool up, as well.
