2017-2023 F350 Timbren Rear Suspension Enhancement System (8600 lbs.) FR350SDJ

Eliminate Vehicle Sagging and Squatting

If you're using your 2017-2023 Super Duty for towing and hauling, 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 heavy loads, fifth wheels and toy haulers and reduce stress on your suspension components. The kit includes hollow rubber springs that deliver a progressive spring rate to minimize rear-end sag. This Timbren Helper Spring Suspension Upgrade replaces the jounce stop on the frame for improved handling loaded and unloaded.

Laser-Cut Powdercoated Steel Construction

Each piece of high-strength steel included in this kit has been precision cut and powdercoated for maximum durability and strength. Installing Timbren's Rear Suspension Enhancement System will help you avoid bottoming out, reduce sag and squat and improve handling under load. Another benefit to these helper springs over air bags is how easy they are to install and maintain, with no fittings, air lines or hassles to deal with. This Timbren Rear Suspension Enhancement System features a 8600 lbs. weight capacity.
