🧾 Overview
The Timbren SES Suspension Enhancement System – Rear Kit for the 2020–Present Jeep Gladiator JT is engineered to eliminate rear sag, sway, and instability when towing or hauling heavy loads. Designed for work, travel, and overland use, this system dramatically improves control and safety without compromising unloaded ride quality.
At the core of the Timbren SES system are Aeon® hollow rubber springs, which provide a progressive spring rate. As load increases, the springs automatically engage and stiffen, counteracting squat, body roll, and trailer sway. When unloaded, the system maintains a small gap between the spring and frame, preserving factory ride comfort.
Unlike air bag systems, Timbren SES requires zero maintenance, no air pressure adjustments, and no onboard compressors. Installation is fast and straightforward, making it an ideal solution for Gladiator owners who tow, haul, or run bed racks and campers.
