Will a ram 1500 bumper fit a 2500?

Generally, many of the Ram 1500 body parts are the same as those on a Ram 2500, but there are some caveats. Across different model years and trims, occasionally You'll find 1500 and 2500 bumpers that aren't compatible. However, if You visually confirm that the fitment looks about right, it usually is. There are times when a bumper just won't "look right", and that's up to You to determine. Different trim styles occasionally swap out bumpers for different looks; and these can vary across model year even farther. However, if You're looking at the same model year (or even generation) 1500 and 2500 for a swap, You're generally going to be okay. Just make sure You're getting into something that's going to match Your 1500, or else it may look a little silly.
