Dodge changed the RAM rear suspension in 2009, using coil springs instead of a traditional leaf spring pack. Therefore, one of the main concerns is ride quality for the Ram 1500, as a coil spring provides a softer ride than leafs, so MaxTrac produced these coils to maintain that comfort. This MaxTrac 202940 rear lowering kit is powder coated in our signature color for long lasting durability, and will drop your 2/4wd 2009-2018 Dodge RAM 1500 4 inches to pair with your new wheels and tires for that low profile look. MaxTrac also offers replacement 4" drop rear shocks for your RAM. The shocks are twin tube, black body, universal gas charged. All the necessary hardware is included as well.
