Eliminate Vehicle Sagging and Squatting with Timbren

If you find yourself constantly using your 2011-2023 GM Sierra/Silverado for 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 loads, fifth wheeler, toy haulers and more to help reduce the overall stress on your truck's factory suspension components. Included in this kit, you'll receive a pair of hollow rubber springs that install in conjunction with your truck's factory setup to help deliver a progressive spring rate while minimizing rear end sag without compromise. The Timbren helper spring suspension upgrade replaces the jounce stop on the frame for improved handling and control when loaded or unloaded, giving you more peace of mind and a boost of confidence each time you get behind the wheel.

High-Quality Construction & Warranty Info

Timbren designed their SES Rear Suspension Helper Spring Kit using only the best materials and latest design techniques to ensure a perfect fit, form, and function on your 2011-2023 GM Sierra/Silverado 2500/3500. The helper springs themselves are made of a durable rubber compound that is capable of handling up to 8000 lbs of the load's weight, and paired with laser-cut brackets that are tough enough to handle just about anything you throw their way. Another benefit to these helper springs is how easy they are to install and maintain over air spring assemblies that require fittings, air lines, and a ton of additional hassles. Timbren includes all of the necessary hardware and instructions necessary for installation, making it a simple and straightforward process you can complete at home. Best of all, this kit comes backed by a Limited Lifetime Warranty to help keep your investment protected.
