This progressive five-leaf pack replaces the factory overload spring on Ram trucks with the 11.5 in. AAM rear axle (4 in. tubes, dual center pin). It removes the sudden rate jump when the overload engages, so the truck rides better on and off road.
It comes with new center pins, 9/16 in. E-coated U-bolts, extra-thick F436 hardened washers and grade 8 tall nuts, and bolts on with hand tools.
2003-2013 Ram 2500 / 3500 4x4 diesel owners who want a better loaded and unloaded rear ride.
