Optimized for those Ram 1500's with a constant load, these “HD” rear springs accommodate contractors and overlanders alike. These springs will operate exactly as Carli's standard multi-rate springs when laden with 500lb. constant bed-load. Detrimental to the performance and stance of our standard multi-rate coils, Racks & Rooftop tents, Camper shells and bedslides, contractor tool boxes, etc. are no longer and issue with our HD rear springs!
