An example of sag on a vehicle's rear axle under a heavy load

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.


Diagram of the Timbren spring installed

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.


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 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.


An example of a trailers swaying

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.


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 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 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 when loaded or towing because the rubber has more travel.

Video Transcript for The Low-Down on the Timbren Suspension Enhancement System

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..

by:

Easy installation. Good quality.



by:

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!

  • Best Timbren Kit for a 2019 Ford Transit T350 Motorhome Chassis
    The best Timbren kit for your 2019 Ford Transit T350 motorhome chassis is part # TFRTR350 rated for 5,600 lbs. The other kit # TFRTR350HD you referenced is rated for 8,600 lbs and designed around vehicles with heavy-duty applications like a service vehicle. The standard kit will give you the best ride quality which is why I recommend going that route. If you were to use the heavier rated kit then the ride quality would be very harsh and you wouldn't enjoy driving your motorhome around.

  • Which Jounce Bumper Replacement Helper Spring for 2021 Ford Transit T250 Camper Conversion
    If your 2021 Ford Transit T250 is a high roof model, the Timbren # TFRTR350 you'd looked at would be a fit. This being said, the Timbren # TFRTR350 which provide a combined 5600 lb capacity would provide a pretty harsh ride, which I'm not certain you'd be happy with. Instead, I'd recommend the SumoSprings # SSR-121-54 which bolt to the frame above the rear axle, replacing the factory bump stops.
