Dodge 3500 Upper Overload Springs

I had a local spring shop add additional leafs in the upper overload pack, but more importantly they re-curved the whole upper pack allowing the overloads to engage sooner. They measured the distance between my old overload springs and the stableloads that I had on at the time to determine the new gap. This means my driving experience (comfort) remained the same for normal empty driving but handling was greatly improved with the camper on. For me it was a great decision, the truck still sits with the rear up a bit and all the sway is gone. My camper is around 4k lbs fully loaded.
