About Us

Lethal Diesel Motorsports LLC opened its doors April 2016 in Staunton, VA. We specialize in Cummins,Duramax and Powerstroke engines. We run diagnostic tests on trucks that come in for repairs to determine the exact cause for it not running correctly and that we may fix it properly the first time around. We will push the limits and get the horse power you desire whether it be for your work truck, daily driver, race truck or pulling truck.
