Specs:
Whether you're hauling heavy loads in your bed or cargo area or you're 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.
The Timbren system comes with custom-fit brackets that are 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, 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.
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.
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.
Because the 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.
Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall when loaded. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.
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 when loaded or towing because the rubber has more travel.

Ryan: Hey everybody, Ryan here at etrailer.com. Today on our 2017 Winnebago with a Transit 350 HD chassis, we're going to be taking a look at and showing how to install the Timbren suspension enhancement for our rear axle.More often than not, these type of vehicles are going to be loaded down with either a lot of passengers or a lot of cargo. That can cause a few things to happen. It can give us that unresponsive steering, it can affect our braking and our suspension feel, and it can also cause our back end to sag. All of those things are anything but desirable. They're going to cause our vehicle to not only sway as we go down the road, but it's also going to cause it to rock.
That's where our Timbrens are going to come into play.Now our Timbren springs are going to replace our factory-style jounce bumpers. They're going to be a major improvement. Compared to our factory-style jounce bumper that I have here, which just sits up there, our Timbren spring is actually going to contact our rear axle the whole time, enhancing our suspension and giving that cushion, as opposed to our factory-style jounce bumper, which more or less is just going to stop our axle from bottoming out.Now our springs are going to be made from rubber, and they're going to be hollow on the inside. That's what's going to help stabilize and level our vehicle. Before I put our Timbrens on, I took our vehicle out for a spin to see how it would perform with the factory suspension.
I noticed a few things. The first thing I noticed when I was going over bumps, that our backend would really come down hard and take a while to recover and reach that original ride height position where it should be. Which in turn, that caused my steering wheel to feel sloppy and just overall throw me around inside.Another thing I noticed when I was making evasive maneuvering, doing some slaloming, could really feel how top-heavy our vehicle was. It was really swaying hard from left to right, the steering was unresponsive, and our brakes we're kind of soft too. Now since we have them installed, let's take it out and see how much better the ride is.
Now as I do some evasive maneuvering, right off the bat you can tell it is way better. Notice a huge difference. There's way less body roll, our steering feels much more responsive, and overall it just feels like it'll be a much safer and smoother ride.Now compared to other types of suspension enhancements such as air bags, we're not going to have the adjustability with these as we would with the air bags. However, these are going to be maintenance-free. All we have to do is put them on and forget about them.
Speaking of which, they're super easy to get installed, so let's go ahead and put them on together now.To begin our installation, we're going to need to jack up our vehicle in a way that our rear axle will come off the ground and hang freely. To do that, you're going to want to jack up one side of the frame until our wheels come off the ground, and place a jack stand under it to make sure you're safe.Here underneath, once our axle is hanging freely, we're going to come over to the factory jounce bumper and we're going to pull that out. To do that, you'll just grab it, work it back and forth, and pop it out of the housing. We'll set that off to the side. Now we can remove the actual housing. It's going to be held in place with one 13mm bolt.Now we'll take our Timbren spring. I do want to point out that the hole in the bottom of our Timbren spring, that will be facing down towards the ground like this. We're going to take our puck and put that on top, followed by our metal bracket. This will sit flat against the top like so. Now what we're going to do is take the included bolt. It'll be the longer ones, are the ones that we're going to be using, and put that through the bottom of our Timbren. Just take a 3" extension and a 16mm socket. Put that over the head of our bolt inside. That'll just give us more control with keeping that bolt up and being able to turn it.While we're holding everything together, what we're going to do is thread our bolt into that factory hole that our original jounce bumper was attached to. For now we'll just turn our bolt by hand. That way, we can get it started. It'll hold itself in place. Then we can come back with our ratchet and tighten it down. Once you have it completely tightened down, you can sneak all your tools out. Just repeat that same process over on the other side. That'll do it for our look at and our installation of the Timbren rear axle suspension enhancement on our 2017 Winnebago with a Transit 350 HD chassis.
Install was a breeze, can't wait to tow our camper with these babies on the Tundra
Would be great to have better instructions and car specific.
So far so good works great, now let's see how long they last?
Fast delivery and easy installation
I actually found that airbags worked better for my truck and trailer. I ordered those from you as well. May I return the Timbrens for at least partial store credit?
Quick delivery and exactly as described!
I have not fully loaded my Odyssey yet BUT compare to original “pacifiers” which are made from kinda tough popcorn, those timbers are looking reliable.
Exact fit and fast shipping!
Easy to install. Works as advertised. Etrailer rocks!
Easy installation. Good quality.
Very easy to install took about 30 minutes. If it manages the weight of my trailer I will be more impressed with your product.
Fast shipping would definitely recommend
Perfect fit for my 2024 Toyota Tundra rear suspension. I tow a trailer every weekend and after installing this rear suspension suppport upgrade, no more squat or swag on truck bed
Very poor packaging. The box is coming apart and USPS reinforced it. Found out this product doesn,t work on a 2018 Winnebago Intent. It will cost me almost $[XX] to return it.
Very easy installation!
Installed this on my 2001 Explorer. Install is easy (assemble unit, bolt on in place of existing bump stop). Annoyed to find it doesn't fit. Specs are gap 1/2"-1-1/2"; there was a gap of 2-3/4". Yeah, they sell spacers for $27 each, but it's really annoying to buy a $225 product that says it fits your truck, only to find that you have to spend 50% more to actually adapt it to your truck!
Easy installation and perfect fit!
Part was reasonably priced and arrived early. Very happy with the process.
Customer service was great. Fast delivery. Very easy to install. 35 minutes it was done.
easy to install, Solved my trailer bouncing over bumps problem.
Service is great and product appears to function as advertised. For what it is seems like product is priced a little high. I'd be very surprised if it costs more than $20 to make them.
Very quick delivery, earlier than I expected. Easy to install. Just what was needed for rear weight support when pulling a trailer.
Great job. Will use etrailer again.
Great product there leveled the load and made tow way better.
Thanks
What a great product. This has made a night and day difference pulling a 5th wheel.
