Summit Racing is constantly in search of new products to add to their expanding catalog for performance enthusiasts. They are now proud to add the brand new Brodix WD Series Cylinder Heads for 2001-15 Chevy/GMC Silverado/Sierra 2500 HD/3500 with Duramax diesel power. These great new heads feature a unique port design for more airflow and horsepower.

Official Release:

Significant performance gains for Chevy and GMC full size diesel trucks.

Brodix, a name long known to hotrodders and racers, just turned its attention to the 6.6L Duramax diesel. Using a unique port design, these all-new cylinder heads flow more air than stock, and deliver more horsepower.

Brodix WD Series cylinder heads are made from A-356 virgin aluminum. Each casting incorporates LB7 injector cups. The heads are a direct bolt on to factory Duramax engine blocks and use all standard components. For even higher performance gains, Brodix offers heads with relocated valve centerlines to allow for larger valves. Each Brodix WD Series cylinder head is sold as a bare casting.

Brodix makes heads for the four different Duramax engine generations found in the 2001-15 Chevy/GMC Silverado/Sierra 2500 HD/3500:
