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.

Video Transcript for Timbren Front and Rear Suspension Enhancement Systems Review

Speaker 1: Today we're going to be taking a look at the Timbren line of suspension enhancement systems. Any time that we add weight to our vehicle, it's going to put a lot of strain and stress on the suspension, especially if we're towing a heavy camper, trailer, or we have a heavy load in the back.Tends to have the back end squat down, which again, it's going to put that strain and stress on the rear suspension because not only are we asking it to hold up the weight of the vehicle, but everything else that we add on to it. Which that can arise a lot of different issues. The front end is going to be getting pulled off, which will misalign our headlights, and our tires won't have as much contact, so our steering and braking is going to be diminished.But tat;s where timbrens are going to come into play. They're going to provide us that extra support so that when we do have those heavy loads, the back end doesn't sag down quite as much, and it's not putting so much stress on the back end. By doing that, the front end's not going to rise up, which means our headlights will be in line and our tires will have the correct amount of contact and pressure, so our braking and steering isn't affected.

And they're going to do that all while making our ride more comfortable with that extra load.Our timbrens are going to provide us the support we need by replacing our factory jump stops and mounting in between the frame and the axle. Now, yours may look different, so you want to double check inaudible 00:01:20 fit guide for your specific application.Now, each one of our timbrens is going to feature a steel bracket. They're all going to have black, powder coat finish on them to resist that rust and corrosion or any other kind of chemicals that may be on the road. They're going to have a hollow, rubber ayon 00:01:36 spring that's going to take a lot of that pressure and strain off of the rear suspension.Whenever we do load our vehicle down, the space between our frame and our axle is going to get smaller. That's where our spring is going to make contact with the axle, and it's going to start compressing.

Now, they are progressively rated, so if we have a small load or a light load, it's going to have a little soft engagement. But the further it gets compressed, the harder and stiffer it becomes, giving us the support we need with those heavy loads.And since they are rubber, they're going to have a lot of give to them, which means they're going to give us the support we need. But at the same time, they're going to give us some more cushion and absorb some of the road shock as we drive. And since the rear ones here aren't in constant contact with our aXle, it is going to provide us the same ride quality when it's unloaded.Our timbrens are going to work independently from each other from side to side. That way, if we have an off center load, it will help compensate for that, but at the same time, if we take an evasive maneuver or a really sharp turn, this is going to help reduce that body roll and some of that sway feeling that we get going on when we have a lot of added weight.Our timbrens for the rear are going to be a good enhancement for any time you're going to be adding weight to the back of your vehicle, whether it be a heavy trailer, a large load in the back or any other situation where you're adding a lot of weight to the back of your vehicle.Now, timbrens on the front are going to be a little bit different.

They're going to provide us that load-leveling support and make sure the front end doesn't get pushed down too far. However, these typically are going to be in contact all the time, which means it's going to give us that support and help reduce on that body roll all the time, all while absorbing that road shock, giving us a smoother ride.Now, some situations where you'd want that extra support on the front of the vehicle to keep it from getting pushed down too much would be if you have a snow plow or winch, if you flat-tow your vehicle, or if you have any other heavy accessory on the front. This is going to make sure that front end stays where it should be, and again, making sure our tires, braking and steering acts how they should.When comparing the timbrens to other suspension enhancement options like airbags, these are going to be a lot easier to install because we're not going to have to worry about running lines, maintaining air pressure, putting in switches or compressors or any of that. Once these are installed, these are going to be completely maintenance free. However, airbags are going to provide us with a lot more adjustability, whereas our timbrens are not going to have that.That'll finish up your look at the timbrens suspension enhancement systems..

2003 Jeep Liberty

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

These do really well for supporting a full load or trailer attached. But if unloaded the will create whiplash if you go over a speed bump or anything that creates the axle to spring up and hit them. 611025

Received my Timbrens very quickly, very well packaged. Installed them is less than 30 minutes. Have yet to hook my rv to the truck, but can see these are going to be really helpful. About 1" to my axle where my OEM bump stops were a good 7" As always etrailer rocks!! Look forward to dealing with these folks when the need arises again. 484817

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


These "enhanced" bump-stops have definitely improved the ride quality of my 2013 Ram 1500 quad cab when pulling our 7500 lb. 29 foot travel trailer. The trailer probably has 500+ pounds of food, clothes, kids toys, etc inside as well. The truck bed probably has another 800'ish pounds of equipment in it that compresses the suspension before I even hook the trailer up. With the stock stops the rear suspension hardly moved. After adding the new stops, the rear suspension had travel again and the steering felt less twitchy. Unloaded truck will hit the new stops only if I hit a pretty harsh bump but it's only noticeable if you're paying attention to it. With a loaded bed (no trailer) hitting the stops is more noticeable but you still need to hit a decent bump for them to touch. They are very easy to install. Take the time to read the instructions and watch the installation video before you pay someone $50-$75 for a 15-20 minute job. I would buy them again. 482362

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


This product seems as described in etrailer catalog and by salesperson. Very easy to install, both sides and clean up 30 minutes (actual install time was about 15-20 minutes). My truck has 100 gal fuel cell and tool box that is pretty full, so I generally have an extra 1200 lbs in bed of truck full time. Looking at truck it sits level instead of rear sitting up a little, not a big deal except headlights aim a little higher and when pulling trailer with skid steer or mini, truck sags an amount that looks overloaded. After installed truck bed height looks close to an unloaded truck. With full fuel cell the truck rests on the Timbren Suspension Enhancement System, I was pleasantly pleased with the ride and look of the truck. The only minor difference is when truck comes to complete stop, there is a slight "jiggle" in truck. Very minor but it is noticeable. I would definitely recommend and purchase again. I can't wait to see how system performs with loaded trailer hooked up. 594996

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I finally had a chance to try these out and they work great. Granted, I do have what they market an ultra-light travel trailer, but for my configuration of my 2007 Dodge Durango (4.7L), this trailer totals out about 75% of my towing capacity. That being said, this vehicle has an abnormally smooth ride for it's size. Because of this, the weight at the hitch creates a slight sag in the rear when weighted over 400 lbs. It also created some suspension characteristics I didn't like, like the slow bounce over undulations. I was advised my shocks were in perfect condition and utilizing stiffer shocks would not prevent the sag and would make the overall ride too tight for me. This was the reason for looking into this option. Installation was as simple as it gets (pull off the old and put on the new). The only tools (if you want to call it that) are possibly a couple of 2x4 blocks (of course you're going to need a jack to jack up your vehicle). 4 inches total was needed to properly seat them. It took a total of 30 minutes, but 20 minutes was me pulling out my jack and jack stands, finding blocks, and taking my sweet time. My Durango rode as level as expected after installation. Photos would not show anything noticeable without actually measuring it (about 450 lbs on the tongue with my particular trailer - see photos). I also didn't have to adjust my mirrors, which was inherent in the slight sag I had before. It took bumps well and the ride was not as bouncy as before, more firm and controlled. The ride without the trailer is noticeably firmer, and with little bumps you can tell they're making contact. Mostly noticeable over speed bumps where my Durango would normally float over them due to the long travel. My Durango inherently didn't ride like a truck or large SUV, more like a sedan. Now, it "sorta" rides more like a truck. Not a deal breaker, but if you like your truck to keep riding smooth, these might not be for you. Pros: Works as advertised. Easy installation. Keeps your vehicle level. Firmer more controlled ride. Removed annoying bounces. Great quality build. Cons: With the clearance from your axel to your bump stop now ~1.5 inches, bumps will be felt if making contact (-1 star for me, but if this is not an issue for your application, you should add the star back). Overall, I would highly recommend this product, even for a smaller SUV like my Dodge Durango. That being said, it won't have the same smooth ride with the long travel as before, but definitely worth it if you're towing with the same type of vehicle. 489147


Comments

After a year of use, the product continues to perform as expected. I have specifically put about 6-8 trips with this product and I have not had any issues. This included many miles on the highways and some trail driving. The product continues to perform well, assisting on absorbing undulations and helps keep the vehicle stable and level. I did not mention this before, but its important to know that this product is only a supplement to an already stable suspension and correctly-weighted setup. If properly used, this product will enhance your driving experience, but it will not fix any overweight or setup issues. I still highly recommend this product.

Piece of cake to install, has no effect on normal ride (which is good). It's too soon for me to give any meaningful feedback re use when vehicle is loaded but everything is positive so far and I can definitely see how they would help under heavy loads. Compared to the standard bump stops these are almost twice the height so the axle will definitely hit these before they would've hit the OE version and give the heavy duty nature of these, combined with the "hollow" design I can envision how they'll add to the stability of the suspension under max loads. 450768

The product has worked as described on the website. They have been excellent as a suspension enhancement. My Durango used to squat 3 and one half inches before installation of the Timbren support. Now when hooking up my boat my Durango goes down 2 inches and stops. I have great support and better control of my vehicle especially when fully loaded on a family vacation. Great product.

Have not tested to the fullest but instalation was not bad once I installed the first side on 2009 Honda Pilot. So far so good. Recomend watching few videos on instaling rear spring and shock absorbers. If equip with tow package, there is an aditional bolt on a stabilizing bar that connects to the arm that will require a 14 wrench and a hex for the tip. Muffler does get in the way to pull the spring but nothing a big push the arm cannot fix. Make sure you have hex tips for your wrench to install. 336553

Working great. I had read reviews about them being too stiff whem you aren't pulling a trailer, but it seems like they softened up a bit after first putting them on. I felt a few hard jolts going over speed bumps and such the first few days, but now I don't notice them at all when I don't have a trailer attached. They are still improving the ride with a heavy trailer. I'd give 5 stars but my mechanic neighbor had to help me install them because there was something wrong with the bolts that came in the package. It was a year ago and I can't remember the details. Without him I think I could have returned them and gotten a fix and installed them by myself. It's a very simple install when all the parts are in good shape. 549083

Product went in fairly easy. Taking the spare out provides a lot of room to work in. A medium size flathead screwdriver worked perfect to get the old ones out. I put one in from the bottom underneath and the other from the outside over the tire. Liked that the best. I was able to hold the product with one hand and slowly lower the floor jack with the other. Haven't given it a good test yet. So far would rate the product as excellent. Would rate etrailer as excellent. Joe 395491

Do you have a question about this Vehicle Suspension?


  • What can I do to Reduce Sag on my 2007 Jeep Liberty by Towing my Trailer
  • If your Jeep is sagging, an adjustable ball mount is probably not going to be the cure. The best thing would be to use a weight distribution system if you have a 2 inch hitch.

It has a 500 pound tongue weight and 5,000 pound gross towing weight capacities. Since Curt does not provide a weight...

  • How Do I Install Timbren Rear Suspension Enhancment System TJRL4 on a 2007 Jeep Liberty

The factory bump-stop is there to cushion the blow of anny sudden or over-loaded suspension travel. As such it needs to be held firmly in place and not allowed any wiggle room. Twist the spring as you push it up to make sure it is firmly seated in the cup, and then bolt it into place.

There are many elements that determine the towing capacity of a given vehicle. The engine, transmission, suspension, and overall structural rigidity of the vehicle should be taken into account.
