You generally CANNOT use tailgates from other models (like 1500 or 2500) on a 3500 dually. The dually's wider track and heavier-duty construction mean the tailgate dimensions and mounting points are different. Even within the 3500 series, compatibility is limited by generation.
To find a compatible tailgate, you MUST look for one from a Dodge Ram 3500 dually of the *same generation and year*. The body style changes significantly from generation to generation. Even a slight year difference within a generation may cause incompatibility due to subtle changes in design.
Therefore, there's no simple list of other models. Your best bet is to:
1. Identify your 3500 dually's exact year and generation. (e.g., 2010-2018, 2019-Present). Pictures can help if you're unsure.
2. Search for tailgates specifically listing your year and model as compatible. Websites selling truck parts will often have this information in their descriptions. Look for reputable sources to avoid buying an incompatible part.
3. Check the part numbers. The part number for your tailgate will be the most definitive way to ensure compatibility. You can find this number on a sticker on the tailgate itself or through your VIN number.
In short: Focus on finding a tailgate from another *identical* Dodge Ram 3500 dually from the same year. Anything else is extremely unlikely to fit.
