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

When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the vehicle 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 install 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..

These work well enough, but they seem to be made for several applications (Toyota pickups, Jeeps) and they are a little long for my 95 Toyota pickup. Truck rides on them constantly, they just barely touch. This makes the suspension when unloaded quite stiff, they are supposed to leave a little gap so the vehicle rides on it's own suspension when unloaded. For towing, they're great. For heavy loads, they're great. If I didn't have a cap on the rear, maybe they would have more of a gap. Oh, and the rear springs have 44K on them, this isn't a clapped out beater truck with 300,000 miles on it, the Timbrens are just a hair too long. Would buy again.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


First, this is the third truck have have put Timbren SES on, so I am a big fan of this option for a pickup truck. There is no impact to the ride when the bed is empty, when loaded it is a big improvement keeping the truck is a level position, reduced sway.. I would have given this 5 stars, except the lower bracket is rusting. All the other parts are painted black except this one part - see picture... This is after one year, truck is parked in a garage in NC (not a high snow/salt state)...


Comments
I continue to be a fan, on my 1019 f150, I used the 1 in spacer, works perfect ! I have dumped 2200 lbs of stone in the bed a few times, no problem.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Highly recommend for anyone towing. Leaf springs were flattened out prior to install. Swapped the bump stops out for Timbrens in a campground before making a 1000+ mile trip home. They work amazing leveled the truck out while towing and absorb the bad bumps.


Comments
I would absolutely buy the Timbren SES again if I didn’t already have them. No issues after a year.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


This Rear Suspension Enhancement kit were so easy to install, I was almost sure I missed something. They installed in less than an hour. I was able to place my floor jack under the ball mount to raise the rear end enough to remove the old mounts and simply install the new ones. Hooked up my 28' rv to my Silverado 1500 and they worked as advertised. No front end sag and I feel safer towing it. Customer service helped me find the right product I needed without dishing out a lot of cash!


Comments
While I have sold this vehicle since this review to my neighbor, she has told me she loves this product when she pulls her rv. I now have a 34 ton pick up and purchased a set for it. I am very satisfied with the Enhancers i purchased for it!

I was very impressed with the easy installation and the performance of the product. I can easily put a 1 yard of top soil in my Ram 1500 and my truck carry it level , no problem. No more snag In the rear. I also find towing a trailer much better. No worries about blowing air bags, this product is maintenance free. Love it, it simple and it works great. Highly recommend

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Never mess with airbags again on your truck. These Timbren bump stops are the only way to go. Installation took a total of 10 minutes and they work amazing. No messing with airlines, filling or deflating air bags with complicated installation. I’m towing a 44ft trailer and these Timbren bumps stops are a must. Great product but a little pricey for what they are.


Comments
After a year of towing some kind of trailer every week, the bump stops are showing some wear from riding on the bump stop pad on the axle. That being said, they are still working as intended and as good as the day I installed them. After a lot of miles, the only draw back is driving around with no trailer. Normal driving the ride isn’t effected but when you hit a bump in the road you really feel it hit the bump stop. You loose a fair amount of rear suspension travel with these but I’m used to it now.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I just installed these on my 2021 GMC Sierra 1500 AT4. It was really easily done and only took .5 hour total. Because the AT4 is slightly lifted I did use the spacers review separately. I am towing a pretty heavy 2 axle horse trailer with a tongue weight between 6000 and 7000 pounds which the truck can handle. When I hitched up with the original bump stops the hitch dropped 4", the frame over the rear tires squatted down 2 and 3 quarters " and the frame over the front tires lifted 3 quarters". After the installation the hitch dropped only 2 and 3 quarters", the frame over the rear tires squatted down 1 inch" and the frame over the front tires lifted . Test drive went well with the same smooth ride with no load as there is no contact. Pulling the trailer went just perfect, no sway due to the trailer design, and the load was very stable with very little bounce.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I had these installed on my 2013 Jeep Wrangler prior to installing a plow. These fill the gap that would allow the front end to dip when the plow is lifted. I also had them in my 2004 Chevy, they stabilize the front end when the heavy load is added.


Comments
I absolutely recommend putting TIMBREN on the front of any plow vehicle. I have now used these on two light duty vehicles. Currently on a 2013 Jeep, the difference is amazing. No more two inch dip when I lift the 480 pound plow. E trailer gets them out to you quicker than expected. I had mine professionally installed so I can’t attest to the directions provided, but there is always a video available now in most everything. The daily ride isn’t much affected because of tire pressure. I do run them a little fuller during plow season. This is a definite win for your plow truck.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I just installed the Timbren Rear Suspension Enhancement System on my 2019 Ford F-150 4x4. The install was pretty straight forward, but I will say that the written instructions were pretty vague. Reviewing the Video on the e-trailer site was helpful. Also the markings for Left and Right could be improved. The marking “L” was very small and baring readable and the “R” appeared to be under some scratch marks so it was not legible at all. I think this product will help considerably. I have attached photos. The clearance between the rubber spring and the bottom plate is approx 1”. I also previously installed the Equalizer weight distribution & 4 way anti sway system to tow my 30’ Travel Trailer. The Timbren is to prevent any slight squat may occur.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


It did exactly what I needed to do. I had really bad chassis roll and soft suspension in the rear of my truck. This eliminated the issue and gave me a stronger ride in the rear.


Comments
I have been carrying an 80 gallon fuel tank tools and equipment with my pick up. Constant weight on the bump stops. There is some wear between the components of the bump stop but they are still solid.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Disappointed. Not in the quality of Timbren's, but in fitment with this particular vehicle. As you can see in the attached picture, there is a 2" space between the Timbren's and the point of contact. 2" is way too much to have to sag or drop in order to even begin to have an opportunity to function. I want it to be known that I am a big fan and buyer of Timbren's, and even have them front and rear on my class c motorhome. In my opinion, a Timbren should only have a 1/2" to maximum of 1" space before coming into contact. Also because of the design, there is no option of being able to use 1/2" or 1" spacers readily available here on etrailer, which I have used with other Timbren vehicle applications. As far as installation, they were the easiest Timbren's I have ever installed. The existing bump stops came out by hand and without using tools. The new Timbren's were pushed into place by jacking up the back of the vehicle and putting a 3" block of wood in between the Timbren and the axle and then lowering the jack and in doing so, pushing the Timbren into place. 10 minute job! Now all I have to do is to figure out a way to design a 1" or 1 1/2" block or spacer to close the gap between the Timbren and point of contact. If I come up with a solution, I will update this review to help out other Jeep owners with this issue.

Best investment for suspension so far!! Had wind, semi’s and large dips in road sway our 2015 Bounder all over the road. With the timbrens installed took care of almost all of that! Big dips, Bounce one time, done. Semi’s pass no issue, Wyoming winds cuts right through!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Received my springs today and had them installed in less then 45 minutes in my driveway, on my 2018 GMC Denali 3500 HD. I followed the advice of etrailer's videos. I pull a 2011 all aluminum self contained toy hauler and use Husky weight distribution hitch. I have not yet taken our trip to AZ from WI yet but will provide further input when we do over the 4th of July. I used a floor jack on the frame rails to provide clearance for installation and did not take the rear wheels off...worked in the wheel wells to remove and install.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


The fork lift operator couldn't reach far enough to center them over my axle, but it didn't matter, because I installed air lift air springs and the Timbren bump stop spring enhancements. I can't believe how well they performed together. It was only a short trip with this load, and I'd never haul this heavy of a payload in a 1500 unless it was a short trip, but it wouldn't have been an option without these enhancements. The fork lift driver was even impressed. He asked me what I was using. These products kick serious ass! AMAZING!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I bought these for my 2001 Chevy Suburban with a 5.3 V8 and four-wheel drive. These Springs have been absolutely amazing, on more than on one occasion I've loaded up three to four thousand pounds in the bed of my truck and the vehicle only sagged 2 in from the unloading height. The Springs are better than I thought they would be and will absolutely be an addition to every work vehicle from now on. I highly recommend them.

Easy installation in about 40 minutes. On heavy truck with dump body and hoist the install has no gap between SES and axle. This is not effecting the empty ride and should definitely improve the stock suspension sag when loaded. Very happy!

Excellent product, very easy to install. It raised the hitch of my 2020 Ram Classic 1500, 2 1/2 inches with the bed loaded and connected to my Coachmen 34 foot Freedom Express Ultralite. I ordered the product while I was away camping and it had arrived when I got back. I installed them while still connected to my camper before it was unloaded. I’m pleased.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Great! However… I installed them on my 2019 Ford E-350 SD Cutaway van, 22’ SRW which I turned into an overlanding rig. Installation was slow but easy with the chassis jacked up. It helped to have 15mm and 17mm regular and deep sockets, and a long 17mm open wrench to tighten the rubber bag nut on top for better leverage since it’s a tight space in the C-channel. Right away I found out that on the passenger side, the brake hose bolted on to the axle was preventing installation of the lower bracket, so I came with a solution which was separating the brake hose from its nest, by installing 2 aluminum spacers (purchased here on[line] for another project) and an 8mm x 50mm bolt. Afterwards, I wrapped the brake hoses with Safe-Spirals hose protectors because the hoses may rub on the brackets at some point.
