An example of sag on a truck's rear axle under a heavy load. The Timbren Suspension Enhancement System levels the Jeep Liberty.

When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the Jeep Liberty sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.


Diagram of the Timbren spring installed

The Timbren system has a vehicle-specific bracket that will be bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits one inch above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride you are used to.


Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape provides increased resistance, stiffening the suspension and keeping the vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when hauling off-center loads.


An example of a trailer swaying

Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer helping to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or passing of a semi) because the movement from the trailer is not transferred to the vehicle. This also works to make the sway subside quicker.


An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened as the rubber springs work to prevent bottoming out on rough roads.


Compared to the competition:

Timbren's suspension enhancement systems are much easier to maintain than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

First Trip with my new Rockwood Extreme Sport to San Diego went well although I had a lot of sag in the rear. Camper place said I did not need a weight distribution for my 03 Jeep Liberty so I got online and found the TJRL4. I ordered it and had my mechanic put them in. We had to call the help desk as they were slightly to big to pop in so he had us shave the top down a bit to fit. My last four trips with the TJRL4 on my Liberty have been outstanding, sag is not an issue and a much better ride. I think if you do not do a distribution hitch , this is much easier way to go. It raised my jeep up slightly also without the trailer on so that is a plus too. The main result was I feel very confident pulling my trailer with a Liberty which went from Arizona to Montana and back, up hills, down hills etc with no problems at all and I was in total control at all times. I credit this to the way the TJRL4 corrected the sag issue. Great Product. 410027

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Just what the truck asked for... I’m a Farrier, I carry a full workshop in the bed of my truck 24/7. I drive a 2001 Toyota Tacoma 4x4. After a couple months I redid the entire front and rear suspension and added heavy duty rear leafs. After about a year of driving and also adding more tools the truck began to sag a little bit. Ofcourse, the first thing anyone suggested was “airbags” but they didn’t know the use of the truck or where the truck goes from day to day. Being a Farrier, I travel on everything from paved freeways to down and dirty “4lo” back roads. I needed a maintenance and care free system that would allow for over extension and hold the extra weight of my tools and sometimes even a trailer. I did a ton of research and even talked to the Technician Staff at each company. I ultimately decided to go with Timbren SES Kit. It’s easy to install, maintenance free, free floating, and has the best warranty in it’s category. Since I have a custom setup (Ubolt Flip Kit from AllProOffroad) I had to design and build some landing pads to allow for an “interference free” contact with my system. After the first day of working, I am COMPLETELY satisfied with its performance and how my truck feels and drives. As for ”Etrailer” I am very happy with all the information and excellent customer service. I received my parts 2 days before it’s orignal date which makes me super Happy! 570702

Great product and installs easily. I did not use the spacer, so this allows the stock suspension about 1-1/2" of travel before contacting the Timbren units. I tow a 16K fifth wheel and the Timbren's handle this load very well. You can see the compression marking on the lower side of the Timbren when the trailer is hooked up to the truck. Just enough contact to keep the truck at a level stance. My stock "bump stops" were starting to fall apart from age and wear/tear. These Timbrens now add an extra level of suspension that makes the truck feel much more in control when pulling the fifth wheel. 574936

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


A year ago, I added Timbrens to my '09 F350 to help carry a '09 Lance 915 camper. Since my truck is a CC LB diesel model, the truck payload and loaded weight of my camper are similar. I found the Timbrens a cost effective way to limit the suspension sag and improve truck/camper sway. When unloaded, I rarely notice the Timbrens as they are ~1.5" away from the spring pack stop and only engage on large bumps. I also like the maintenance free aspect of Timbrens. To further enhance the loaded ride, I am replacing the thin factory contact pads on my overload springs with larger ones. I found that adding the Timbrens limited suspension travel such that it prevented adequate overload spring engagement with the factory pads. The replacement overload pads from Torklift and Supersprings are 3" (too much IMO as they contact the overload spring nearly all the time making for a rough ride). I am cutting down a set of Superstops to ~1.5 - 2" for the right amount of overload spring contact and Timbren engagement but still maintaining unloaded ride quality. 570372

Rear suspension pads work great. Ride is still like factory with no load unless driving over a big bump at high speed. When towing a 32 foot travel trailer the sag in back end of truck is greatly reduced with a lot more control. Easy to install. The downside is when truck is full with passengers and not towing anything the added weight makes the ride rougher. Shipped on time. 575558

My 2015 F-350 dually would always squat when I’d hook up my fifth wheel. Towed it for the first time since purchase and install and the truck is nice and level. The ride is better also and after driving a bit without the camper I don’t really notice them. I love the simplicity of these over airbags and imagine they won’t be needing any maintenance or replacement anytime soon. Great simple solution. Not so easy for an old fat guy to install laying under the truck in the driveway but I managed! 442491

They work. It is nice towing nice and level now. The ride with the load on is good and smooth and very stable. I am still very happy I went them. Put them on and forget about them, no maintenance and no worries.

The Timbrens are great. I have not had the truck with a full load yet but I anticipate they will help bring the truck back to level. The install went well but we were not able to use the additional spacer even with the longer bolts. We were not able to put enough pressure on the bolt to get the nut started. I don’t believe I will need the spacers so it should be ok. The directions didn’t include the amount of torque that was needed so I sent e-trailer an email. They checked with Timbren and the torque is 1/4 turn after they are tight. Ive attached some pictures of the completed install. 566262

These are an awesome suspension up grade. Great for beefing up a half ton. I installed front and rear timbrens on my 02 tundra and im carrying 2000 lbs. Level, no suspension sag and have had 2800 lbs on still handled ok with no droop. Down side is they ride really rough if you do alot of dirt road / off-road driving. I don't recommend those load weiights with 6 ply tires move up to 10 ply. 573504

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Caveat: I just installed these and have only road-tested unloaded. 1. As usual, etrailer filled my order quickly and accurately. 2. Installation was as easy as advertised. I did not have use of a lift and did it in my driveway. I did not remove the tires. I lifted one side at a time, blocked all other wheels and used a jack stand to back up my bottle jack. Hint #1: the higher you lift the truck, the more clearance you will have to work over the tire and insert your socket into the jounce stop and Aeron spring. Hint#2: The hole in the bottom of the factory jounce stop is small. Use a 3/8" drive 10mm socket. My 1/2" 10mm socket wouldn't go in the hole. 3. Installed, I ended up with a little more than 3/4" clearance. My road-test showed me that the Timbren SES has NO influence on unloaded ride unless you drive like an eedjit and hit speed bumps too fast (which I purposefully did.) Once you eliminate the 3/4" clearance between the SES and the axle you'll feel the extra stiffness right away, but it was not a shocking hit. I'd describe it as "authoritative." I'm happy. 566992

Great quality products at a great price. Fast shipping and delivery. Easy installation with the included instructIon sheets. The Timbren SES provides a much smoother ride with regular shocks than the previous setup of coil over shocks alone. The 7 and 4 pole trailer connector provides the flexibilty to pull my teardrop trailer which has brakes and a 7-way plug or my utility trailer which has a flat 4-way plug without adapters. Fantastic customer service. Etrailer.com has a great selection of products for your vehicle and traveling needs. 570293

I own a 2006 GMC Yukon. We purchased a brand new 2017 32' Keystone Hideout Travel Trailer. The travel trailer remained well within our tow capacity when fully loaded. We also purchased and installed a weight distribution system. With all of these steps in place, the rear of our vehicle would sag. I purchased the Timbren SES Rear Suspension Enhancement System (Model TGMRG25C) from etrailer. The order arrived quickly within a few days. I was able to install myself in about 30 minutes. We just took the travel trailer out this past weekend. From the moment we hitched the trailer on, the difference was remarkable. No rear end sag at all. I would highly recommend this product. 433738

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I owned these for about a year and just recently switched to air bags instead. While the Timbren spring helped level the truck under load, there were other things that I was not satisfied with. One issue was the amount of distance the truck would drop until the Timbren would engage, I would have like to see them take affect sooner. I did not like the ride while empty. When hitting a decent size bump in the road the spring would slam into the stop causing for a very jolting ride. Also while under load and the Timbren was engaged, it made the truck extremely bouncy. Again it did stop the truck from further squatting under heavy load, but the other factors were what made me switch out for air bags, to which I have been very happy with. 565705

I just wanted you to know that prior to my installation, this Coachman with a hitch weight of 700+ pounds would push the rear down so much that there was barely daylight between the tire and the wheel well...but look at us now. This '04 Titan with 189,000 miles and original suspension is riding high. Your product helped me get the bed level and has reduced the sway on the trailer so much that it is hardly noticeable. I am very happy with my purchase, your follow-up and the results. 564348

Comments

Timbren suspension systems wont have a whole lot of effect on vehicle ride except during cornering or when the vehicle is under load. Once a load is applied to the suspension, either from cargo or from the tongue or pin weight of a trailer, the suspension will compress enough for the Timbren Aeon springs to contact the axle.

Product came securely packaged and complete and quick. Took about 45 mins to install. I bought this to try to reduce the 3 1/2 inch sag at the hitch of my Lexus GX460. It did that well. I now only sag 2 inches that I feel is acceptable. The trailer has about 484 lbs weight. The ride doesn't seem affected and towing bounce(porpoising) is gone. Thank you etrailer. 560925

I’ve had these for a year on my 2006 Toyota Sequoia. Purchased them after taking my wife’s horse on a long road trip where we damaged the trailer jack on our horse trailer. The Toyota has a sport suspension and would bottom out when we hit big bumps. These keep it from bottoming out and also help prevent trailer sway. Affordable and very easy to install. Unlike sway bar nothing to hook up when towing and it doesn’t change how the vehicle drives. Completely satisfied! 565135

I installed the front and rear Timbrens on my 2017 Georgetown GT5 class A. The installation was pretty easy, except for the tight areas getting the wrenches on the bolts. The front passenger side used the original bolt to install on my frame. Installation took about two hours to complete the front and back. It would be quicker if you use power tools, but I wasn't in any hurry. I've driven on two trips now with them, and they made a noticeable improvement on the rocking sideways back and forth. The motor home seems a lot more settled now with wind and traffic. 563687

Kit does a great job making up for the underbuilt suspension on my excursion. Installation was straight forward although a bit awkward from under the truck in the driveway.

Performs as advertised. We pull a 5th. wheel travel trailer. Very little bed drop. Applicable to a 2015 GMC 2500. Had a problem finding a shop to install. So, installed my self which was rather simple and easy. Took about 30-45 minutes. Could do it in 20 minutes now. Tools you should have ready. Large screw driver, 2, 6 inch or so length of 2x4, hydraulic jack to lift truck bed. Pry the old pieces out, place both units in position, lift bed enough to put 2x4 beneath. Drop bed and compression will fit into place. Lift bed, remove 2x4, drop bed, You are done. 562908
