We do have air springs, like the Firestone Coil-Rite Air Helper Springs # F4185, which fit your 2014 Ram 1500, but what it sounds like you need is a weight distribution (WD) system. An air bag kit will help support your suspension but it will not increase your weight capacity. A WD system works by distributing the tongue weight (TW) of your trailer evenly among the axles of your Ram and your trailer for a level ride. We also recommend using one of these if the trailer weighs at least half of the weight of the tow vehicle.

Without knowing what the weight of your trailer is I can't really make a recommendation but I can give you some tools to help you figure out the best WD system for your application.

When looking into purchasing a WD system you want to find one with a TW range that the Total Tongue Weight (TTW) of your towing setup falls in the middle of. To find the TTW of your towing setup you will need to add the TW of your fully loaded and ready-to-go trailer, which you can which can be found using # e99044. Keep in mind that a properly loaded trailer will have a TW that is 10-15% of the loaded weight of your trailer.

Once of the best WD systems out there is the Reese Strait-Line, like part # RP66084, which utilizes sway cams to prevent sway from starting. This particular system is rated for 600 lbs - 1,200 lbs of TW. If you let me know what the TTW of your system is I can recommend the best WD system for your towing setup.
