The XHD Full Replacement Leaf Springs designed for those with constant 2,000lbs in the bed . Designed for the pop-up campers like the Four Wheel Campers Hawk. Although, it will work with ANY 2,000lb. constant load. This is NOT a leaf spring pack designed to run unloaded, it requires the 2,000lbs 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.
