Get the Helper Springs you need for heavy hauling with your 1998.5-2002 Dodge 5.9L 24V Cummins Available in multiple load capabilities, these spring packs install with u-bolts, or other hardware which secures it to the existing suspension components on your truck. In most applications, the helper spring sits on top of the factory leaf springs and works in conjunction with the original spring pack. This helps to increase the load level rating up to the stock GVWR. SuperSprings and Hellwig are just some of the manufacturers you can find to help you get the most out of the suspension in your truck.
