Isuzu trucks are some of the most versatile diesels on the road. They are used commonly in landscaping companies, tow companies, and aftermarket parts suppliers. When running correctly, the Isuzu truck can carry a large load and gets much better fuel economy than the bigger diesels out there. 441 Diesel has recently invested in the IDSS diagnostic software from Isuzu. This allows us to have the capability to program ECMs, perform diagnostics tests, and adjust vehicle top speed without having to send trucks out to Isuzu dealers. If you have any questions for us about our Isuzu capabilities call us at 706-677-0060.
