DHD 801-101 Duramax Diesel Stock Keyed Camshaft
The Stock Duramax uses a 5mm dowel pin to keep the engine timed. Its common to see high mileage or high horsepower engines with damaged or sheared dowel pins. We here at DHD offer a solution for that problem.
Our DHD stock improved camshafts are modify to accept a straight keyway for added shear strength and dependability. All camshafts are cleaned, inspected and have polished bearing and lobe surfaces. Camshafts are shipped with a keyway. Use the picture below to help you determine which camshaft you need.
Fitment:
Camshafts with two bearing surfaces with oil galleys are for 01-10 Duramax. This second oil galley is used for turbo supply lube.
Camshafts with only one bearing surface with an oil galley fit 11-16 LML Duramax. The turbo is supplied oil differently on a LML.
