Our Story
Your Home for
Performance Diesel Parts.
Southern Diesel Supply LLC was founded in Mount Dora, Florida with a clear mission: give diesel truck owners access to the performance parts they need, backed by real technical support from people who actually know diesel engines.
We specialize in diesel performance parts and accessories for the most popular diesel truck platforms — Ford Power Stroke, Chevrolet and GMC Duramax, and RAM/Cummins. From turbochargers and fuel systems to tuning and driveline components, we carry the parts that matter for serious diesel builds.
What sets us apart is our approach: we are not just an online parts store. We have a real diesel facility and real diesel techs available to help you find the right solution for your specific truck and goals. We have helped diesel truck owners upgrade, customize, and enhance their trucks across the United States and beyond.
