Quality Rear Suspension Helper with Progressive Spring Rate

If you find yourself constantly using your 2011-2023 GM Sierra/Silverado for aggressive towing and hauling applications, it's only a matter of time before your suspension starts to sag and squat under the constant pressure of your trailer and heavy loads. Timbren's rear suspension enhancement system is designed to enhance your existing suspension setup to support heavier trailers that teeter the edge of your truck's GVWR, helping reduce the overall stress on your truck's factory suspension components. It's important to note that this kit will not add to your truck's GVWR, but allows you to tow closer to the stock range by helping reduce the overall weight of the load. These premium units feature a progressive spring rate to give you consistent and reliable performance each time you get behind the wheel.

Simple Bolt-On Installation & Warranty Info

Timbren manufactured this kit using only premium materials and most advanced design techniques to ensure a perfect fit, form, and function on your 2011-2023 GM Sierra/Silverado. These springs replace the jounce stop on the frame of your GM Duramax, giving you enhanced ride quality whether your rig is loaded or unloaded. To ensure overall improved ride quality, there should be a 1/2†to 1-1/2†gap between rubber spring and axle to give you the best of both worlds. These springs easily install to your truck's existing suspension setup using the included hardware and instructions provided by Timbren to make for a simple and straightforward process you can complete at home. Timbren backs this kit with a Limited Lifetime Warranty to help keep your investment protected.
