About Us

Ram Diesel Specialist Logo Brennan Healey truck cummins


Expertise begins with passion and commitment. When Clessie Cummins founded Cummins Engine Company in 1919, he took his expertise in marine engines and developed the first diesel powered automobile.  Cummins' innovative and brilliant engineering created the technology that today boasts the most stout and reliable engineering of all diesel engines.  RDS may not ever make the record books or be found in the Automotive Hall of Fame like our hero Clessie Cummins, but we are inspired by his perseverance, dedication and commitment to excellence.

Ram Diesel Specialist is proud to provide an array of services for all trucks with Cummins engines.  From Ram 2500 - 5500 series, 1st, 2nd, 3rd, 4th and 5th generation Cummins engine trucks, and all commercial vehicles powered up by Cummins, we stand ready to help you with an array of diesel repair issues from engines, axles, steering suspension, brakes, transmission, and our favorite, electrical issues.  We love the challenge of finding the solutions to tough problems!
