We are Southern Utah's premier diesel performance shop. Whether your oil-guzzling jalopy needs a lot of love, or if your shining beast needs more growl beneath the hood, we're your best choice for the upgrade. Founded in 2005, Smith Diesel Performance and Repair has grown year after year because of one simple business model: "Provide quality work at a fair price." When you do that, word gets around fast and there is no better advertising than word of mouth.
