More than three decades ago the doors of a small, independent rebuilding shop opened, Auto Dynamics Engine. Word of quality workmanship and excellent customer service spread quickly, and the business grew. From small beginnings in Casper, Wyoming came the largest engine remanufacturer in the Rocky Mountain Region. Auto Dynamics Engine has grown to provide remanufactured engines and service to North America as well as overseas. Throughout our growth and development, Auto Dynamic Engines continually preserves the values that we began with, to build a quality engine at a fair price. At Auto Dynamics Engine each engine is built and tested one at a time, by people who care. Only the best name-brand parts are used in our engines. Auto Dynamic Engines is proud of our hardworking people, with their many years of expertise. Our motto has always been, “If it is not good enough for our own vehicles, then it is not good enough for our customers.” At Auto Dynamics Engine we refuse to build an inferior engine. Our engines are built to be the best. To back up that claim each engine comes with a 3 Year Unlimited Mile Nationwide Warranty. Never compromise quality for price. Get the performance you desire at a price you can afford.
