      Description

      Eliminate Sag. Prevent sagging and squatting on your next haul with the Timbren SES Suspension Upgrade for the Rear of your Wrangler. They're maintenance free and don't require airing up or adjustments like other options on the market. As a direct, bolt-on replacement for your JK's factory bump stops, the SES Suspension Upgrade ensures an even stance when towing or under heavy load.

      Superior Ride. This unique suspension upgrade is crafted from quality rubber to create durable hollow springs. They deliver a progressive spring rate, providing resistance and reliable leveling properties when under load. Unlike the harsh contact made by factory bump stops, these replacements provide a superb ride on and off road, even while towing or under heavy load.

      Application. The Timbren SES Suspension Upgrade Rear Kit is designed for use on all 2007-2018 Jeep Wrangler JK and JK Unlimited models. Sold as a pair.

        Gets the job done

        I have an 08 JK with a snowdogg plow and without these bump stops the front end sagged so bad. These are a must have if you have a plow..

        5 2016 Wrangler - Theo Installation Time: Less than 1 Hour

        No more hard slams when loaded down!

        These bump stops are absolutely awesome and work fantastically. I have added a bit of weight to my jeep with a full roof rack (Gavin Expedition), rear bumper that holds 2 5 gal. cans which are full. Then once I load in my camping gear if I hit a hard bump the bump stop slams down sounding like it is about to break something! I took a chance on these Timbren stops and let me tell you they work fantastically! The install was a bit of a pain in the tail, I ended up having to soap them up and then using a 4x4 block letting the weight of my Jeep press them in place. They are no where near as soft as the factory stops and will just pop in and out by hand. However, as much of a pain getting them installed was they resolved my issue and now when I hit a really hard bump, fly over a speed bump or am rocking through the trail, they hit soft and quietly as can be! If you are having bump stop slam issues, just buy them and you won't regret it, at least I don't!

        Excellent

        I tow quite a bit lately, mostly my boat, but on occasion I end up towing a vehicle. These really help keep the back end from squatting so much during tows. Pretty easy to install and nice design. No complaints

      • The Timbren Rear Axle SES Suspension Upgrade will replace the factory bump stops inside of the spring.

      I have a 1" spacer lift on my 2017 JKU Rubicon. I tow a travel trailer frequently and want to overcome the back and sag. Will I have to remove the spacers to use these?

      • Removing the spacers is necessary, however you will have that 1" of suspension travel before these work, so some sag would still be noticeable.

      I want to put a plow on my Jeep Wrangler 2017. Smoky mountain edition. I don't want the front to sag down to much . What do you think ? Shocks , leveling kit ???

      • So this will certainly help with sagging and squatting and would be a worthwhile addition to your Jeep with your goals in mind.

      Hello; I am purchasing an 'off-road' camper-trailer to tow behind my stock 2016 JK 2-Door. The 'off-road' camper-trailer will be under the towing (2,000lbs.) and tongue (200lbs.) weight limits as specified for my JK. My goal is to limit any potential rear-sag while towing. Does anyone have an opinion or recommendation regarding the Timbren 'bump-stop / jounce' SES suspension upgrade or an 'air-helper spring' suspension upgrade? Thanks!

      • Yes, the Timbren SES Suspension Upgrade - Rear not only Eliminates Squatting & Sagging but they are Perfect for Towing & Heavy Mods. We definitely recommend them for your particular application and needs, they will work great.

      I have a 1-1/2" leveling kit in the rear and a 2" leveling kit in the front of my 2013 JK. I am looking to cure the rear end squat when towing a boat trailer. Can these SES Suspension Upgrades have an additional spacer added to take up the additional 1-1/2" space in the rear end from adding the 1-1/2" leveling spacer under the stock springs?

      • Currently there are no spacers available for the Timbren SES Suspension Upgrade to allow for this large of a gap. A custom spacer would most likely need to be made in order to take up the gap.
