Single-convoluted springs are shorter and wider, designed to resist weight more aggressively. The 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. Ideal for tractor trailers, tow trucks, trucks with spreaders, dump boxes, cranes or aerial devices. If your vehicle is not listed, please call our technical department at 1-800-243-3194.
