Boost Driveability and Turbo Response on Your Duramax

If you’re looking to squeeze more drivability and towing confidence out of your 2001–2016 GM 6.6L Duramax, the SoCal Diesel 3388AF Tow/Street Alternate Fire Cam is designed with exactly that goal in mind. Unlike more aggressive race cams that sacrifice street manners, this cam delivers smoother engine operation while helping your truck handle heavier loads with less strain. One of its biggest benefits is its ability to lower exhaust gas temperatures (EGTs), making it perfect for tow rigs or daily drivers that see highway miles under load. It also helps improve turbo spool-up when running a larger-than-stock turbo, which means better throttle response and usable power when you actually need it most.

Designed for Real-World Use Without Compromise

Another great feature of this cam is that it requires no valve reliefs, so there’s no need for costly piston modifications during installation. While custom tuning is required to take full advantage of the cam’s alternate firing design, the end result is a more refined, responsive engine that’s easier to live with on the street and more capable when towing or hauling. Whether you’re upgrading for better reliability on long trips or looking to enhance the performance of your workhorse without going over the top, the SoCal Diesel 3388AF Tow/Street Cam delivers smart, real-world performance gains you’ll appreciate every time you hit the road.
