Give your 1989-1993 Dodge 5.9L Diesel the Helper Springs you need when towing heavy cargo. 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. Available in different load capacities to help fit your needs, these springs install easily using u-bolts or other hardware to your existing suspension components. 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.
