Swap Specialties and Performance is proud to introduce the First company ever to offer BRAND NEW Duramax Standalone Harnesses and Computers. It’s the same way we build everything else, start with the highest quality wire, OEM connectors, and proud labor. We build it with a weatherproof fuse and relay box and give you all of your hookup wires as well (fans, ign, fuel pump). Then, we build the harness on an actual motor and actually run it on the engine dyno to assure everything is 100% tested, perfect fitment, and backed by the best warranty in the business. We offer a variety of engine and transmission combos, please let us know if you have any questions!
