Have a 1500 loaded down with tool boxes, overland rack, rooftop tent or work gear? Is your back end saggy and not leveled. These HD coils can be just the fix for you! Optimized for those 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 Carli's standard multi-rate coils, Racks & Rooftop tents, Camper shells and bedslides, contractor tool boxes, etc. are no longer and issue with Carli's HD rear springs! To be clear, these are NOT coils for guys who occasionally tow or sometimes throw a thousand pounds in the bed as they DO have a higher spring rate to accommodate load. This will cause a higher rear stance and stiffer ride when unloaded
– it’s precisely why we only recommend these springs for trucks with a constant bedload.

FEATURES:
Provides 1/4-1/2" Rear Lift Progressive Rate Requires 500lbs constant load in the truck bed
