Tuff Country EZ-Ride Suspension’s 2? lift kits for the 2003-2012 Dodge Ram 2500 and 3500 4wd trucks are simple to install lift kits that allow for slightly larger tires and more fender clearance. Upper coil springs spacers lift the front of the Ram 2500/3500 while maintaining a factory ride. Kits are available with rear add-a-leafs that are added to existing rear leaf springs or rear cast iron lift blocks that are installed below the factory leaf springs to gain additional lift.
