Dual Fuel Serpentine Belt for GM 6.6L Duramax

If you’re running H&S Motorsports’ Dual High Pressure Fuel Kit on your 2011–2016 GM 6.6L Duramax, the serpentine belt might not be the flashiest part of the system—but it’s definitely one you can’t overlook. The H&S Motorsports Dual Fuel Serpentine Belt is the exact belt included with their dual fuel setup and is specifically sized to work with the added components of that system. Whether you’re replacing a worn belt or building a custom fuel system from scratch, this belt is designed to keep everything spinning smoothly. It routes perfectly with the extra high-pressure fuel pump in place, maintaining proper tension and accessory alignment. Trying to make a standard belt work in this setup just leads to headaches, so if you’ve added a second CP3 or are running one of H&S’s kits, this belt is the one built to do the job right.

Fits: 2011, 2012, 2013, 2014, 2015, 2016 GM 6.6L Duramax
