Upgrade your 2011-2016 Chevy/GMC 6.6L LML Duramax with new leaf springs. Leaf springs are a key component of your suspension and not only allow you to carry and tow heavy loads, but they also help make your daily drive more comfortable. Common symptoms of worn-out leaf springs can include sounds from the suspension while you are driving, sagging in one or more corners of the truck, and a rough ride. Shop the wide selection of leaf springs available and restore the ride and handling of your truck.
