This SES Suspension upgrade fits the front suspension of a Jeep Wrangler TJ, JK and JL. Each laser cut piece of steel is precision welded and powder coated to ensure a quality fit. We've engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs (weight from a snowplow or heavy aftermarket accessories such as a steel bumper) the harder they work to prevent front end sag. This SES Suspension Upgrade replaces the jounce stop inside the coil spring. Its unique design ensures superb ride quality loaded or unloaded. (There should be a 0.5 Inch to 1 Inch gap between rubber spring and axle to ensure unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.
