Axels & Frames
The 2500HD & 3500HD Duramax Diesels came equipped with the AAM, 14-bolt rear axle with an 11.5 ring gear and 3.73 gear ratio. We stock single wheel, dually, and cab chassis rear axels that come complete from the rotor to the rotor with hubs & calipers. All are inspected and carry our 30-day parts warranty. We also carry rear axle parts for repair – axel shafts, ring & pinion, carrier assemblies, housings, hubs, etc. We also stock ready-to-drop-in front differentials, CV shafts, and suspension parts—freight shipping on all axels & parts available.
Frames for the 2500HD & 3500HD Duramax Diesel are offered several different ways to fit your project. Whether you need a bare frame, frame with suspension, complete rolling chassis, or just a frame cut, we have you covered with a wide variety of cab & bed configurations for 2001 – present models. Clean, southern frames and New GM frames make a great base for any project.
