Longhorn Fab Shop

At Longhorn Fab Shop, our goal is to make all of the customized parts and tools easier for you to purchase, understand, and install.

Our experience comes from a combination of educational principles and hands-on experience. Our background consists of theoretical knowledge and principles to understand the systems that make diesel trucks so powerful. Plus, our hands-on experience with some of the largest automotive manufacturers in the world gives us an edge in both the aftermarket parts and tuning world. Our experience allows us to understand why the automotive manufacturers makes the decisions they do, which parts are necessary, which ones aren’t, and what things they do only because they are required by government standards. This all make it significantly easier to know what to modify, why, and in what way to get the results you’re looking for.

We take the guess work out of buying performance parts for your Duramax by applying individualized information for each product, including our own experiences, pictures from previous installs or what we learn from our customers. If you can't find the information you are looking for, feel free to contact us and our customer service team will answer any questions you may have and give personal insight into previous installations we’ve performed.

We only list products that we truly believe in. If we have issues with the quality of a product and it is not something we would put on our own trucks, we aren’t going to sell it to you. With so many products out there, it is hard for one person to have experience with all of them—and that's where we come in.

We are confident that any product you see in our online store is something that you will enjoy installing and getting use out of it. If there is any product you would like to purchase and do not see it on the site, please feel free to contact us and we will be more than happy to get it ordered for you.
