Reduced rear axle sag with Timbren suspension enhancement

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


Diagram of the Timbren spring installed

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the leaf spring sits, 1" 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 that you are used to.


Action 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 increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your 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 you are hauling off-center loads.


Trailer swaying as it is towed behind a truck

Because your vehicle handles better with the springs, less turbulence will be passed along to the trailer and this helps 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 a passing semi) because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.


An empty truck on a bumpy road without Timbren SES

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 because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Rear Suspension Enhancement System Review

Today we're gonna be taking a look at a popular upgrade for your pickup trucks. It's the Timbren Suspension Enhancement System. All you gotta do is put your vehicle in the fit guide, just to get the kit that'll have a custom bracket so it'll fit the truck. There's a lot of different ways that you can beef up your suspension and a lot of options on our site. But I like these the best, because it literally took me maybe 15 minutes to install. So if I we're to compare this to airbags, airbags are kind of a pain, you have to run airlines you probably need a compressor.

And if you don't get a compressor, you gotta run out and air them up. They're a little bit more customizable, but you don't really have it completely dialed in. With this, the stop is exactly where it is, and as your suspension starts to sag, it'll kick in right away and there's a lot less maintenance and it's the most cost effective way to kinda beef up your suspension. So if you want my opinion, this is the way to go. So here is what we added today.

So we basically just replaced the factory bump stops. So there's a lot of different situations where we're gonna really need these. We'll notice the gap down here. We're gonna have a lot less of a gap than we did with the factory system. So, if your vehicle sags under a load whenever you have a lot of stuff in here.

You have a 450, you're planning on doing some pretty big stuff with it, so a lot of the times it'll make your headlights just go way up bright and you're blinding everybody that you're driving against. Also with less of a load on the front wheels, we are going to have a little bit less good steering and handling just because of the weight transferred to the back. So, you bought a big old truck, you're planning on doing quite a lot of heavy hauling, so this isn't going to increase our capacity of our truck. It is gonna have a limit of 12,000 pounds, but it is going to do a lot for you, what Well, a lot of that sag whenever you have a lot of load in the back, what happens is it starts going like that. One, you're gonna be that guy on the highway that everybody's flashing lights at because once your front end starts to raise, it's gonna look like high beams and you're gonna be blinding everybody.

You don't wanna be that guy, trust me. Also, whenever that weight kinda transfers to the back, there's gonna be less weight on the front. So less weight on the front, that's what steers. We're not gonna have near as good of handling as if we have these on, and it's a little bit more level to where we keep the weight kinda distributed a little bit more. Also with the leaf springs, they're gonna engage a lot quicker with the Timbren Suspension System. So your leaf springs aren't gonna be working a whole lot. It's gonna limit trailer sway and all sorts of stuff. So if you really just wanna kind of protect your truck and just make the whole riding experience a little bit nicer, it's definitely the way to go. Whether you're hauling with a ball mount, or a gooseneck or fifth wheel, it's not gonna have any interference with the gooseneck or fifth wheels in the bed of your truck. So you don't have to worry about that. Some of you guys we're wondering, and Adam's saying, it's not gonna be a problem. So one, I like the black color, 'cause it doesn't really stick out like the factory ones. And also these are a lot smaller than the ones we put on here, there's only about a finger's length in between there. So they're definitely gonna engage even with some of the lighter loads. And that'll do it for a look at the Timbren Suspension Enhancement, and I'm Adam with etrailer..

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


About a 1/2 inch difference in gap at the bump stop perch but still within parameters. Truck sits perfect with trailer attached. Haven’t towed yet. After towing if they perform like they should will upgrade to a 5 star. Easy to install, definitely needed 2x4 and jack. 2011 Silverado ext cab with 30 ft Genisis 5th wheel.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I have used Timberns on 2 other vehicles, a Toyota 4Runner and an S10 Blazer with out complaint.

I transport RVs as a contractor for an RV transport company. My truck is 2021 Ram 3500 crew cab, 6.7 diesel.

Because the weight of the units is different with each unit I haul I wanted an easy, no maintenance solution to maintain as level a ride as possible. I haul both bumper pull and 5th wheel units. In addition to the weight of the unit I'm hauling I can carry 110 gallons of fuel with both the factory fuel tank and my auxiliary tank. Additionally, there is the weight of my Curt 25K 5th wheel hitch, Curt 14K equalizer hitch and bars, and approximately 300 pounds in tools.

I don't have to worry about airbags not inflating. The suspension settles about an inch before making contact with the Timberns. Squat while loaded is negligible. The ride empty is the same as it was before installation. The ride loaded is smooth and controlled even when hitting large bumps at highway speeds.

Installation was simple and straightforward. It took me about a half hour.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


They definitely support and did lift my 2014 toyota tundra up about 1.5 inches.
This application with my weight has trunk riding on the cushions all the time.
That has teavel and bounce issues that do make some driving situations interesting.
I may go ahead and replace with airbags but for now support things well!




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I think I will be very happy with the ride when I tow our fifth wheel, it definitely needed the extra support especially on rough roads.I chose not to use the spacers because I like the softer ride when the truck is unloaded.




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Haven’t had it on long, but so far so good. 1999 F350 dually. Bolted up nicely. Total job took 10 minutes. Have hauled two gooseneck loads of hay and truck drives SO much better. Nice and level. Money well spent so far.




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I haven’t hooked up to the fifth wheel yet or else it might be a 5 star. Based on the 15 minute installation time and the price compared to air bags this appears to be a logical way to go. I will update this as I hook up and put a load on it.

I have the timbren enhancement system on my 2020 canyon. I haul a trailer with Ranger that I pull about 250 miles to hunting camp. It tows great!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


The timbrens actually did what they were suppose to do. However, once I starter driving out west I notice the timbrens were riding on the axle which cause the speedometer to jump around depending on the road. I would recommend them if you are hauling or towing a camper or RV. I was going to contact etrailer about maybe removing a spacer for one set however the other set came as one unit. The bottom line is the Timbrens does stabilize your load for safe travels. I will be contacting etrailer soon to assist in correcting the problem...Road trip from Idaho,Colorado,Wyoming,and Utah were beautiful... Thank you etrailer

The Timbren rear suspension enhancement system helped with the truck swaying side to side when the slide in camper is on the truck.
The photos show right and left rear with Timbren’s installed (2 photos), with slide in camper on the truck (2 photos) and when the camper was removed (2photos).

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Installed these with only one issue, which was on the driver side rear axle. The axle had a ABS sensor cable bracket on the axle that need to be readjusted and trimmed down. The BumpStock was hitting this bracket on one edge. So actually, it's not and exact fit. But this issue is really a FORD placement issue of that cable. So just be aware that some extra work may be needed to install them. Passenger rear side install perfectly. Next is the drive to see how much better the coach drives, heard great reviews on that

Great product, it works perfect on my truck. Sometimes I tow up to 30k lbs including my trailer and my truck stays level. No more high beam flashing in my eyes from drivers going in the opposite direction on the road.

Worked great on our 2019 Honda Odyssey Elite to the East coast.Fully loaded with 4 people and a car top carrier,the Timbrens kept the van stable and level.
Sold the 2019 but took the Timbren system out and put them in our new 2022 Elite. Very easy to install, highly recommend.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I used this on my Isuzu tow truck. The blocks in and of themselves are fine, they support the weight. Here's the problem: They are pre-loaded, meaning that they always touch between the frame and the rear axle. As you load the vehicle this puts more pressure on the frame in this 5" area where the blocks are. The springs have not yet taken as much weight as they normally would. Now, all this upward pinpoint pressure bends the frame. This is what happened to me on my rollback tow truck. After many hours and now double plating the frame all is well again, but a tremendous amount of work. Yes, the blocks are fine, but the result of installing this product resulted in a bent frame. The vehicle was not overloaded and was within the GVWR.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Too early to give a ride review but I received the TFFF53B fronts and the TFRF53A rears for my 2019 Fleetwood Southwind 35K while at a campground this week. Easy enough to change out while there. It is about.a 2 hour job to change out all 4. The front right took me the longest and you have to reuse the existing bolt. A washer should be provided because the hole in the bracket is almost as large as the bolt head. I will be placing a large flat washer there. The rears took less time to change.. I used the first and third slots in the mounting brackets and they actually put the unit more over the center of the axle than the original bump stops. Same was true in the front. No clearance issue or interference with my trac bar.


Comments
Have had these on my RV for over a year nowhere and I am completely satisfied. The fact that these always maintain contact with the axles greatly reduce body roll on turns and uneven roads.

I will say they are perfect for towing but when your not towing cause they are so close to the bottom it feels stiffer when not towing! They should make long enough so that it touches besides that these are perfect

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I really like these Timbren bump stops. I think the best thing about them is the simplicity, both how they work and how easy the install was. I bought these when I added a dump insert (similar to a salt spreader) into my 2019 F-250. I have loaded this truck heavy before with dirt and the truck sagged tremendously and had a lot of body roll. To prevent this with the now added dump insert, I installed these. Super easy to install! Took maybe 30 min. It reduces body roll and seems to improve the ride depending on how loaded the truck is.

One unfortunate consequence to the install is that the Timbrens brought to light that I have a weak leaf spring on my passenger side, which was suspect previously.

Overall, I'm very pleased with this purchase and would buy again!

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


Ok, the drivers side was very easy to install. Maybe 15 minutes. The passengers side was another story, the rear bolt was very difficult to get at and took a great deal of time and creativity to get the bolt tight do to no room to turn the wench.
That being said it did improved the ride a great deal with no load, I drive country roads that are very rough , it completely stoped the wheel hop and provide a much better ride.
I would recommend installing these I’m glad I did! I would give this 5 stars if it were not for the passenger installation.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Product is high quality, all parts fit well and I didn’t have to force anything. High strength thick steel, and the jounce bumpers are seriously heavy duty. I haven’t had a load on the truck (98 Ram 3500) since install a few days ago, so they haven’t touched the base plates yet.

One thing I’m concerned with is the jounce bumpers are touching and are right up against the lift blocks and U bolts. I’m unsure of the longevity these bumpers will have after a heavy load is on them and they are constantly rubbing on the hardware. Also, as the load gets heavier they expand outward as they flatten out so I’m also concerned with if that will push my lift blocks outward and mess with the suspension.

I’m prepping for a slide in camper and when I get it I will have to take a look and see what effects that weight has on the suspension, the bumpers, and ride quality.


Comments
I am not sure when I will be able to have a load on it to confirm, as I do not have a camper just yet. I am currently working on upgrading the suspension in preparation for one. Is there an alternative similar solution, other than airbags - as I dont want those, that can be run? With a similar weight capacity? Kind of interesting Timbren hasnt run into this issue before with the older Ram 3500s. Wonder if this is somehow unique to my truck? All the rear components are original OEM, so it seems kind of strange.
-- comment by: Jimmy - 01/05/2022
You mentioned that the jounce bumpers were touching up against the lift blocks without a load in the truck and I wondered if you could send a picture of the installation?
-- Etrailer Expert Jenny N - 01/05/2022
I do have additional questions for you. Is the top picture showing how the springs look with a loaded weight? Have you already installed your slide in camper? I wanted to see if the top bracket were touching as well? The manufacturer is trying to determine if a smaller diameter spring would help or not
-- Etrailer Expert Jenny N - 01/05/2022
Both pictures are right after installation with a completely unloaded bed. Since installation, I have not had weight in the bed, so I can not 100 say if the top brackets would touch the U bolts or leaf springs. But from looking at it just now, it appears the top bracket would just barely touch the U bolts with a loaded bed, and would definitely touch if there was side to side movement with a loaded bed like going over a speed bump, pot holes, or uneven terrain.
-- comment by: Jimmy - 01/05/2022
I did hear back from Timbren. Currently there is not a bracket that would be narrower that they can offer. When loaded if the brackets interfere with the smaller spring, then it may be advisable to return the kit.
