I have already installed sumo springs on the rear and that made a huge difference in the ride and handling with the camper on the truck. After installing sumo’s on the front the side to side roll with camper is almost nonexistent! When the truck is empty it still rides like stock. EXCELLENT product!

Front sumo springs (800 lbs) on my 1 ton truck. Made a huge difference in cornering and securing the front end

When I put a 1700 dry weight camper on the truck with stock off road suspension there was at times an uncomfortable amount of sway and porpoising. The Sumo springs, 800# in front and 1500# in the rear, resolved the issue. Very pleased.
