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.

Hello everybody, this is Jeff at etrailer.com. Today we take a look at the Timbren Rear Suspension enhancement system. Now this is a custom fit part. It is designed to fit the 1967 to 1999 Ford F 800 medium duty trucks and on a custom fit part like this, I do recommend for you to go to our website. Use the fit guide, put in your year model vehicle, and it'll show you if this'll work for your application. Now this will improve the suspension handling and the safety of your vehicle.

This does provide additional support as needed. So you always have a nice, smooth, comfortable ride. It will allow the leaf spring ample movement while cushioning light loads and it does not affect the empty ride of the vehicle. And then it will become more rigid as more weight is added. Increases the Stability, provides great performance for hauling heavy loads and it'll even help reduce vehicle sag.

These will work independently side to side help compensate for any off center loads and will reduce body roll when swerving and turning corners. These do act as shock absorbers. Taking the brunt of bumps and rough roads helps extend the life of your vehicle suspension. That it will include everything laid out here on the table. The two Aeon hollow rubber springs.

The vehicle specific brackets. All the hardware needed for a nice simple installation. Now your set of instructions. That'll describe how to install it. And these do install directly onto the frame.

No drilling required. Few Specs, Again the capacity on this is 8,600 pounds. Now the Timbren Springs will not increase your vehicle's weight carrying capacity. So you do want to make sure not to exceed the manufacturer's recommended weight limit. And these are designed to work with a suspension system that is in good working order, but that should do it for the review on the Timbren Rear Suspension Enhancement System..

Strainer/basket is holding up well after one year of use in our RV, no issues.



by:

Work great. No longer bottom out when towing my trailer



by:

Works great on my Honda odessey !! Great customer service as always!



by:

Offers firm suppirt for loads. A little bouncy with no load. Easy to install.



by:

Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.



by:

The product first arrived in a damaged box with one of the washers missing, but ETrailer did resupply that. The hardest part was finding a shop able (needs the right tools to depress coil springs) and willing (a potential liability issue messing with suspension) to replace it for a reasonable cost. Eventually a local tire shop agreed to. This was for a 2014 Honda Odyssey, especially for pulling a pop-up. Took two camping trips last summer, one before and one after installation, and I have been pleased with the added stiffness in the rear suspension. It made about 1 to 1.5 inch of difference in resting position when fully loaded and towing and has helped smooth out bumps and humps in the road - both when towing and not.



by:

Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.



by:

Excellent quality, good prices and great shipping ! Thanks



by:

Fast Shipping



by:

BIG difference in handling a load or trailer ... what a great product!!!



by:

Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.



by:

Delivery was fast, instal was quick & easy. Later today I will see how they work when I hook up to the 5th wheel. By all indications right now I believe they exceed my expectations.



by:

I put this product on my Trooper. The install was easy is you take the back wheels off. I towed this weekend and I did not bottom out. If they hold up over time, this is a great product.



by:

I would recommend this product to anyone. I pull trailers with a 1/2 ton truck and will never have another one without this product on it.



by:

Price was good compared to other sites. Shipped very fast. Installation was very easy.



by:

Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too



by:

Fit and functions as described. Installation was simple on my '05 Silverado.



by:

It took longer to move the floor jack under the truck then to install them. Maybe 10 minutes total. Thanks Rex



by:

15 mins to install and what a difference…. Went from a few inches of sag in the rear to only an inch and over 1000lbs tongue weight didn’t know the trailer was attached to the truck



by:

This product was delivered quickly and efficiently. The quality of the product is excellent and look forward to seeing how they work when we are towing our trailer.



by:

Holding up good a year after purchase, work great for pulling my camper



by:

Easy to install, took a lot of the weight of as expected.



by:

Noticed a significant decrease in the sag on my 250. Pulled great and would definitely recommend these to anyone on the fence about purchasing



by:

Great product, great service. No more blinding oncoming traffic when I’m loaded or pulling my boat. Truck stays nice and level



by:

I have used this before and it works very well

  • Timbren Helper Spring Fit for 2007 Ford F-650
    The Timbren # TBDR750 measures about 9-1/2 inches in height, from the bottom of the spring to the top of the mounting bracket, so that's not going to work for you. I spoke to my Timbren representative, and was told that given the 6 inches of clearance you have between the axle tube and the underside of the frame member, you'd want to use part # TFR650LP. The # TFR650LP sits right about 5-1/2 inches tall which will leave a 1/2 inch gap, which according to Timbren is acceptable, as they'll...

  • Suspension Enhancement for a 2001 Ford F-650 with a CAT3126B Engine Hauling Cars
    You do not have to have an on-board compressor to use air springs such as # F2363. You can use a stand alone compressor like in a shop or gas station. The use of the air springs will improve the ride quality by not allowing the suspension to bottom out. For a softer ride you would use less air. The differences in vehicles makes it difficult to quantify ride improvement. Also variations in the amount of air affect the ride quality so it is tough to say how much better the ride will be. However...
