Founded in 1938, Gomer's – US Diesel Parts began by serving the local farming communities in and around Great Falls, Montana. While much has changed since those early days, our commitment to quality and service has remained the same. Over the decades, Gomer’s Inc. has grown alongside the diesel industry—expanding our expertise and reach to serve diesel customers across North America.

Today, we specialize in diesel fuel injection parts, turbochargers, diesel engines, transmissions, suspension components, and high-performance diesel products. We carry parts from the most trusted brands in the industry and continually expand our inventory to meet the needs of modern diesel vehicles and equipment.

In addition to being a retail and wholesale distributor, we also provide professional automotive and diesel repair services at our shop in Missoula, Montana. From parts to installation, our experienced team stands behind everything we sell.
