Helper Springs will give you the support you need in your suspension when towing in your 2007.5-2010 Chevy/GMC 6.6L LMM Duramax. Most helper springs are located on top of the factory leaf spring pack and work in conjunction with the OE springs. The added support to the factory spring pack increases the load rating up to the stock gross vehicle weight rating. 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. Shop today and upgrade your suspension with top-notch brands such as SuperSprings and Hellwig.
