The Ram 3500 Platform was designed to haul, nothing surprising, right? The factory leaf springs are a NIGHTMARE when it comes to ride quality. We have several Suspension Systems adding various levels of ride quality to the platform, none more than those tuned around the Full Replacement Leaf Springs. There’s no substitute for swapping the factory leaf springs in favor our our progressive packs but this comes at a cost to the factory payload. Deaver (our leaf spring manufacturer) doesn’t assign a numeric value to the capacity of thee leaf springs – they’re tossed into a category of “light 3/4-ton” capacity or, slightly reduced from a factory equipped 2500 Ram.

This is a big deal for those who purchased a 3500 for it’s designed application, towing/hauling that want to run our systems for the coveted ride quality gain. The Carli Suspension Long Travel Airbags are now available for the 13+ 3500 Platform. The tapered piston, folding sleeve bag will not interfere with the ride quality of your suspension when not inflated and the internal bump stop in the bag affords an operating range of 0 to 100 psi (bags are rated to 2,000lbs./ea. at 100psi), suitable for big 5th wheels, work trucks, campers, boats, bumper pull trailers and hauling.

The Airbags will travel 12″ and run an industry standard 1/4″ airline and can be plumbed into existing on-board air systems. We provide everything needed to install the airbags and set them up for manual fill. Again, these airbags were designed to work in conjunction with our Full Progressive Leaf Springs to regain the lost payload capacity and create an adjustable solution for varying loads. These will work with add-a-packs as well but are better suited to the full progressive leaf springs to provide the best unloaded ride and payload capacity.

Lastly, this kit includes all air fittings, schrader valves and 1/4″ airline to set the bags up for manual fill OR to plumb the bags into your exiting compressor system.

NOTE: Carli Long travel airbags will ONLY work with rear lifts that level to a 3″ Front lift. We recommend 1″-2″ of lift in the rear. These will NOT work on stock height trucks.
