2014 model year 2500's got radius arms up front like the 3500's and all new for 2014 is the rear coils on 2500's, 3500 duallies maintain leaf springs. Did you see how they were able to get the 3" lift. From their press release it sounds like they kept the stock coils and did some sort of spacer on top of the coils. IMHO Ram needs to take that design and make that the standard for the Power Wagon. I would trade my wrangler in for that. AEV has done a nice job with the design clean and factory appearance.
