Helper Springs will give you the support you need in your suspension when towing in your 2008-2010 Ford 6.4L Powerstroke. Made in different load capabilities to fit your application, spring kits install easily using u-bolts, or other hardware to secure it to your existing factory components. 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. Shop today and upgrade your suspension with top-notch brands such as SuperSprings and Hellwig.
