Carli rear progressive leaf spring kit for 2010–2013 Ram 2500/3500 gas applications provides a 1" rear lift and a two-stage progressive rate by Deaver Spring. Engineered to preserve a "light" 3/4-ton cargo capacity while improving ride comfort across terrain, the packs reduce axle wrap and wheel hop, allow up to 15" of suspension travel with the factory shackle, and soften initial spring rate at ride height.
