Hi Robert,

I checked with all of our manufacturers for you and there is not an air bag kit that is a fit for your 2005 Dodge Ram 3500 cab & chassis dually. There is one option that will work for your truck, which is the Timbren Rear Suspension Enhancement System # TDR3500CA.

While Timbrens won't give you the more customizable load support of air bags, they'll still be an upgrade for your suspension. Reason why is they'll take the brunt of added weight at the rear of your truck from towing or a heavy load, engaging when needed to counteract sag and body roll, helping level and stabilize your Ram.

I have added a link below to a video of the # TDR3500CA being installed on a 3500 cab & chassis dually if you'd like to take a look.

Hi Robert, how did the Timbrens work out on your Ram 3500 cab and chassis? It’d be great to hear how they handled the load support and ride quality. Your update could make it easier for the next person with the same setup.
