2017-2019 GM 2500HD/3500HD 6.6L L5P Duramax Helper Springs

One of the smartest moves you can make for improving the towing and hauling capabilities on your 2017-2019 GM 6.6L Duramax L5P is adding on a set of aftermarket helper springs. Helper springs are designed to reduce the unsightly rear-end sag that often occurs when your GM 2500HD/3500HD is loaded down. They work by propping up your truck's suspension which not only helps level out your truck, but also enhances its overall ride quality and comfort which gives you a smoother and more controlled ride. Combine them with some new Rear Shocks and experience the ultimate towing and hauling capabilities. GM Duramax Fitments: 2017, 2018, 2019 GM 6.6L Duramax.
