These Heavy-Duty Rear Mount Suspension Enhancement Systems are designed specifically for tow trucks and car carriers. These systems reduce jounce stop on the frame, eliminate sway, decrease tire wear, and improve handling. Single-convoluted springs are shorter and wider, designed to resist weight more aggressively. Hollow rubber springs deliver a progressive spring rate - the more weight that pushes down on the springs, the harder they work to prevent rear end sag. Whether you're pulling a trailer, or carrying a heavy load in the bed of your truck, the springs adjust automatically to keep the vehicle level at all times. International 2000, 3000, 4000, 5000 models, 2000–2015 feature a 15,000-lb. load capacity.
