Who we are
Big Sky Auto Diesel & Exhaust was founded by longtime friends and seasoned professionals David and Sean. With over 60 years of combined experience working on Ram diesels, Jeeps, and everything in between, they built this shop on values that matter: honesty, precision, and relationships. After decades in dealership service departments and corporate repair shops, they wanted to bring dealership-quality service—without the dealership price tag or hassle—to the community they love.
