Heavy Duty How-To | Upfitting Ram Trucks with Ram Engineers

Share Post

If you’re in the upfit business there’s a good chance you’re already comfortable under the hood of a Ram truck. However, the Ram Trucks brand understands that with each subsequent model year, or each additional upfit design in your portfolio, new questions will arise.

To help answer your upfit questions, the Ram brand offers an extensive online Body Builder’s Guide and also maintains a direct phone line to our engineering department in Auburn Hills (manned by real people!). In an effort to lend further support, the Ram brand is supplementing existing resources with even more helpful information in the form of a video series featuring advice, tips and tricks from actual Ram brand engineers.

Below are the first seven videos in the series, with more videos and upfitter topics coming soon. If you have questions you’d like answered by a Ram brand engineer, please leave them in the comment section below. Enjoy!
