GM Duramax Parts

MadJack Diesel Performance is proud to provide you with a huge selection of high-quality and affordable 6.6L Duramax diesel parts. From fuel, transmission and oil filters to transmission pans and differential covers, we carry all the Chevrolet and GMC Duramax performance parts you need to keep your engine running at its best. Whether you’re repairing a Duramax truck from the early 2000s or upgrading and customizing your 2015, you’ll find that our selection and prices are very competitive.

We source parts from the same manufacturers GM uses for their OEM line and their AC Delco line. These parts are the same parts as name-branded ones, without the big name and we sell at discounted prices. We also carry the name brand parts you expect to have available to you. We supply the exact same filter or part that you would get at a major retail store at a reduced cost.

We love our Duramax trucks whether they be GMC or Chevrolet just as much as you do. We strive to offer high-quality parts without the price tag these usually command. Our Duramax OEM, aftermarket and performance parts are going to fit, work and last. We understand that towing RV trailers, boats and hauling heavy loads takes a toll on your engine. Having the right parts helps your truck work efficiently for as long as possible. If you have questions about which parts will work best on your GM Duramax equipped truck contact us today! Our staff is extremely knowledgeable, experienced, courteous and ready to give you the time and service you expect when spending your hard earned money.
