From Carli Suspension
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. The truck for which they were built scaled at 11,740lbs (5,400 front, 6,340 rear).
As with the XHD springs, these will have a custom-order lead time AND require custom tuned Pintop Shocks (different tuning than the XHD shocks) to support the massive spring rates and load capacity of these springs.
