Timbren Rear Axle SES Suspension Enhancement System with Spacer Kit (17-26 F-250 Super Duty)

Improved Hauling Capability. Simpler than air bags and just as strong, a Timbren Rear Axle Suspension Enhancement System (SES) is an easy way to eliminate any suspension sag or squatting. Unstable loads while towing and hauling don’t just make for an uncomfortable ride. Difficult handling, rear sag, and corner sway create dangerous driving conditions — for you, your passengers, and other vehicles.

Rugged Aeon Rubber. Our Aeon® rubber springs deliver a progressive spring rate. As load increases, our rubber springs push back harder, eliminating squat, sway, and roll. After installation, there should be a ½” to 1 ½” gap between the rubber spring and vehicle’s frame — meaning you’ll enjoy a comfortable unloaded ride, too.

Do-It-Yourself Installation. What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, our kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.

Spacer Kit Included. Timbren SES spacer kits reduce the gap between the Aeon® rubber spring of our SES kit and the increased distance between your lifted pickup’s frame and rear axle - enabling your Timbren SES kit to perform properly. Each spacer kit comes with two 1 inch and two ½ inch spacers, along with necessary hardware — so you can mix and match the spacers to achieve desired height.

Application. This Timbren Rear Axle SES Suspension Enhancement System and Spacer Kit is designed to fit 2017-2026 Ford F-250 Super Duty models.
