CS-DFSP-19-425-XXHD | Carli Suspension 1" Lift +3500lbs Leaf Springs Kit For Dodge Ram 3500 4WD | 2019-2023 | Diesel

The XXHD Full Replacement Leaf Springs designed for those with constant 3,500lbs in the bed – designed for CAB-OVER campers; although, they will work with ANY 3,5000lb. constant load. This is NOT a leaf spring pack designed to run unloaded, it requires the 3,500lbs load to sit at the intended height and properly function. Being a far heavier spring rate than our standard leaf spring AND designed to operate with a much higher center of gravity, we recommend 2.5″ Remote Reservoir Shocks & custom shock tuning for optimal control and ride quality. We do not have this tuning profile for the 2.5″ Pintop but we DO have a custom tuning profile to match these springs to the Dominator System.

Overland with a large cab-over camper or build an off-road rescue rig, these XXHD leaf springs support a 3,500lb. constant bed-load.

Developed for the massive, flagship, off-road race-rescue truck, we’ve sold these springs to many customers with custom flat-beds and large, fixed campers. So long as you’re around the 6,500lb. rear axle weight (confirmed on certified scale), these will be the perfect means of suspending your adventure rig!

As with the XHD springs, these will have a custom-order lead time AND we recommend a minimum of a 2.5″ Remote Reservoir shock to support the massive spring rates and load capacity of these springs. Unfortunately, we do not have these tuning profiles for the Ram – we’ll need to get a local truck with these springs in to develop this tune for the XHD, time permitting. If you have a local shock tuner that can dial these in, that would be ideal.
