The ICON Dodge Ram 1500 rear coil springs provide 1.5″ of lift height and feature a dual rate design with ICON-engineered ride and overload rates. This dual rate design allows for a soft rate at ride height for superb on-road comfort and a firmer secondary rate that increases during compression for excellent payload support, bottoming resistance, and off-road performance. Like all ICON coil springs they feature a lifetime guarantee against sagging/breakage to produce confidence in knowing that you have the best suspension products available for the 2009-2023 Dodge Ram 1500.
