Reduced axle sag with Timbren suspension enhancement

Just like the rear of your vehicle will sag under the weight of a fully loaded bed, the front of your vehicle will sag when under the burden of heavy equipment such as a snowplow. In this case, the front axle is handling not only the weight of the equipment, but also more of the vehicle's weight. Overall vehicle 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.


Install diagrams of Timbren hollow rubber springs

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your front axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down so that the bottom of each spring touches the axle. Because each spring is making constant contact with the axle, it is always working to cushion and support your factory suspension.


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're carrying off-center loads.

A snowplow mounted to the front of the truck will require extra suspension support for the front axle.

Timbren's Suspension Enhancement System will help raise the front end of your vehicle when you're using heavy equipment like a snowplow. This ensures that your headlight beams will be pointed in the right direction and tire wear will be reduced. If the plow is off-center or has an extension, the springs will automatically compensate for this as well.

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 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. More elasticity allows for a more comfortable ride because the rubber has more travel.

Great product, but I had to go buy my own hardware to mount ,the nuts that came with kit would not fit the bolts way too big.



by:

Very fast delivery, good product, worked as advertised. It solves the sagging when my trailer is hitched.



by:

Perfect fit, easy to install, and they work as advertised. These are a nice improvement over the stock parts.



by:

Haven’t used them yet, it was an easy install, everything I needed.



by:

Excellent quality, good prices and great shipping ! Thanks



by:

So far everything is working. Just as I though. The only complaint I have is the wait time that it took (12) days from the order date to when I receive the item.



by:

RV handles curves much better then before, more solid handling.



by:

These are exactly what my truck needed for the heavy loads I put into the bed.



by:

nice ride with my 5th wheel



by:

I have not put any weight on it yet so that will come later. I have a 2007 G.M.C. 2500 H.D. and I pull a 40 foot Big Horn Traveler. What I want to talk about is the install. It was quick only took about a hour. Take the tire down and start. Had no problems it went just like the video showed. I did not use the big washer I didn't have enough room.I have about 1 inch of travel before they come in to play so ride is the same.



by:

Takes the sag out for a bargain, but not as good as real springs



by:

Super easy to install. After reading several reviews about this product and how folks went about installing, found that I just needed to remove just one of the U-Bolts and just barely loosened the second. Replaced both in about 30 minutes. Shipping was quick and was exactly what I ordered. Reviews were helpful and will definitely use etrailer again.



by:

Really makes a difference when hauling a heavy gooseneck.



by:

Bump stops I bought from you are way bigger and so much better than oem. Only took less than 30 minutes to install. It was very easy to install.



by:

great delivery time. I received them this afternoon and installed them in about an hour. thanks to the video that showed everything step by step. thanks for a great product. I think this is just what we needed to help haul our camper and pull our car hauler at the same time. thanks again



by:

Superb. Exactly what was needed.



by:



by:

Product fits as described. Will try out when I tow my travel trailer in a few weeks.



by:

Great product, easy to put on. It took less than 45 minutes to put the new Timber butt stops on. Only thing I would request is to tape up the box they cam in, because by the time it travels to your location it’s beat to hell and back. Like the last time I ordered the ones for the front, all the parts were missing. Luckily this time all items were still in the box.



by:

Got them this morning as promised. Haven’t put them to the test yet but installation was a breeze, 30 to 45 minutes. That includes putting away the tools and washing my hands!



by:

Works great with my slide in camper easy install great product will do the front next



by:

Came just as advertised. Waiting to install. As an aside: You might want to make sure all box sides are securely taped as the USPO delivered the box with the un-taped side completely pulled away from the box and the suspension parts were pushing out of the box.



by:

Works great. Helps to stabilize my large toy hauler behind my Ram Truck while traveling. My truck stays level with the heavy load.. Highly recommend.



by:

Product arrived on time. Installation was easier than the video. Only took me 20 minutes.



by:

Every thing I got from you guys is all great . Thanks for checking !!

  • Front Axle Air Spring Kit for Lifted 2004 Ford F-250 4WD
    Timbren front axle kits # TFF350SD4 and # TFF350SD4B that fit the stock 2004 F-250 4WD are both considered standard capacity but part # TFF350SD4B does have slightly taller and stiffer springs. Otherwise they are essentially identical no-drill replacement bump stops. But neither of these can work on your truck with 6-inch lift. No Timbren front axle kits are safe to use on a truck with 6-inches of suspension lift. I did call Timbren to confirm this is the case. It may be possible to install...

  • How Much Clearance for Timbren Front SES for 2004 Ford F-350
    The Timbren # TFF350SD4 are approximately 3.75" tall. Ideally you want a 1" gap after installation. If it is a little less that is fine they will just engage sooner.

  • Will the Timbren Front Suspension Enhancement System Fit a Lifted 2004 Ford F-250
    Yes, you should be able to install the Timbren Front Suspension Enhancement System part # TFF350SD4 on your 2004 Ford F-250 with Old Man Emu ARB Leaf Springs. However, if the distance between the bottom of the frame and top of the leaf spring pack has changed which I can only assume it has then you will need spacers to fill the gap until you have around 1/2" - 1" from the bottom of the Timbren and top of the leaf spring pack. The Timbren spring and bracket will measure 4" tall therefore...

  • Timbren Front Axle Jounce Spring Kit for 2002 Ford Excursion 4X4
    The Timbren front-axle jounce spring kit that fits your 2002 Ford Excursion 4X4, part # TFF350SD4, installs in place of the vehicle's factory bump stops so their installation should be totally unaffected by the Bilsteins. The kit is a no-drill bolt-on installation that uses included custom brackets and hardware.

    The Timbren Rear Suspension Enhancement System, item # TFREXC4, is only the rear kit for your 2001 Excursion 4x4. For the front suspension you will need the Timbren Front Suspension Enhancement System, item # TFF350SD4. These front suspension helpers will definitely help with the large 7.3L motor in your Excursion. Both of these kits will require the removal of the original bump stop but will not require shock or spring removal and do not require any modifications to the original chassis....

  • Suspension Upgrades for 2004 Ford F-250 4x4 with Air Bags, Overload Springs, and Anti-Sway Bar
    The first thing you are going to want to do is make sure that the truck payload capacity is high enough for your 3,500 pound camper. Adding suspension enhancement does not increase the capacity of the truck. It sounds like you have just about everything that you could use to enhance the suspension. Beyond that, all the components that you added to the rear suspension could be putting extra stress on the front. You could upgrade the front coil springs using # SSC-31. Or add some jounce-style...
