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 service and very fast delivery. It took about 20 minutes to install. The video help in gathering all the right tools one time. Getting ready for a road trip and we will see what improvements it does. The stops rest on the spring so it should take the sway out. I did notice when someone was walking on the floor that the stops did have some give in them. Thanks Korren for great service that you provide. 901826

2018 Ford F-53

Installed rear Timbren suspension last year- very impressed with the performance. Ordered the front and received them the day they were supposed to be shipped (per estimated shipping time) 876925


Best investment for suspension so far!! Had wind, semi’s and large dips in road sway our 2015 Bounder all over the road. With the timbrens installed took care of almost all of that! Big dips, Bounce one time, done. Semi’s pass no issue, Wyoming winds cuts right through! 869068


I'm very please with the results. Takes lot of the hard jult out of the frt end. I would recommend these to anyone. 862582


Helped with the smooth ride 820993


Great jounce type rubber springs and cheaper than the "other brand". Easy install too. I had these on in about an hours time tops! They make the ride more stable and ends a lot of that wheel jump when hitting road cracks, pot holes, bridge seams, etc. Less wheel shack. I put these on the front of my F-53 chassis and Thor Ace Motor Home. Worked out well and does what it is intended to do. My. only wish was that this style of unit would fit the rear of my F-53. 808436


Products arrived as advertised, exactly as I expected with no issues. Easy install. I won’t hesitate to shop this site again, always a positive experience. 808131


Reviewed with the vent covers I purchased. I would highly recommend adding these or other suspension products especially for Class A. I chose the Timbren because I could install them without taking the tires off and without drilling any additional holes in the chassis. 801483


Product is as represented. Thank you. 799185


The front and rear kits came yesterday and I installed them today in my pole barn while the winter weather blew out side. Will try them next month! I am 75 years old and did the install myself , the rear took the longest as it is a tight area. My unit is a 2017 Georgetown XL Thanks for the videos and info online. 756552


The Staff of etrailer were outstanding in helping with my orders. Packages came in a day early (that was great) 751361

2005 Ford F-53

I would have given 5 stars, but it is difficult to get a socket on the frame/ to bracket mounting bolt. I would suggest a cutout/ scallop on the mounting bracket to facilitate installation. Now for the road test. 683011

2017 Ford F-53

I installed the front and rear Timbrens on my 2017 Georgetown GT5 class A. The installation was pretty easy, except for the tight areas getting the wrenches on the bolts. The front passenger side used the original bolt to install on my frame. Installation took about two hours to complete the front and back. It would be quicker if you use power tools, but I wasn't in any hurry. I've driven on two trips now with them, and they made a noticeable improvement on the rocking sideways back and forth. The motor home seems a lot more settled now with wind and traffic. 563687

Its been a year now owning the Timbrens on my RV. and they are holding up great and work great on stopping the rocking back and forth. I recommend them to anyone whos considering upgrading their suspension.

2017 Ford F-53

I can’t believe how effective these are on my F53 Ford based motorhome, the before and after is night and day. I would not want to be riding down the road without it. 551279


Review from a similar Aeon Spring System in Vehicle Suspension

this is the second set of Timbren springs I have purchased, the first set was on my Ford Raptor, they took all of the sag and sway out of pulling my boat. I have this set on my 2015 GMC Denali 2500HD, I pull a 42 ft. 5th wheel and the Timbren's take all of the sag and sway out, these are in my opinion the best product I have purchased for my truck. 683687

this is still an amazing product! works as good today as the day I installed it. I recommend this to all my friends.

5 stars. Easy to install and made a big difference when pulling a 9k pound travel trailer. I would recommend it to anyone pulling a trailer. Kept it from sagging and level. 699184

Review from a similar Aeon Spring System in Vehicle Suspension

Installed this on my 2009 Caravan because when I had a hitch mount 4-bike platform rack hanging off the back and was loaded with camping gear and family, the rear suspension was terrible, it would bottom out, and my headlights pointed up so that everyone would flash their brights at me. New shocks helped, but did not solve the problem. This product did fix the problem and I am very happy. I was concerned about the feel when the van us unloaded, but this has not been an issue. I highly recommend this product. 796869


Review from a similar Aeon Spring System in Vehicle Suspension

I first put the Timbrens on the rear to help stop bouncing and porpoising on highways and bridge ends when towing. The rears have a gap and do not touch the springs until the truck is loaded, working great and keeping a smooth unloaded ride. The front Timbrens fit snugly and touch all the time. The ride is firm and a bit harsh with my unloaded truck having a snow plow spring option. When my trailer 30 ft trailer is hooked up, the front of the truck is slightly lighter. Towing with the Timbrens is nice and the bounce and rebound porpoising is very controlled. I would like the front Timbrens to be a little softer when the truck is unloaded, but I think these units are a nice add-on for better control, safety, and preventing damages. I had the fronts installed at the shop when rotating tires and a front end alignment. The rears installed easily. 691475

They have worked out great when towing my 30 ft trailer. We took a coast-to-coast trip across the northern USA and into Canadian Rockies and excessive bouncing was controlled. I still would like the front to be a bit shorter and not always touching, so the unloaded ride would be less harsh.

Delivery by etrailer was fast. Their advice as to proper application of the Timbrens saved me lots of money! 749745


Review from a similar Aeon Spring System in Vehicle Suspension

So far they look great. I will put on this weekend and see how they work with my travel trailer. 476068


Review from a similar Aeon Spring System in Vehicle Suspension

After a 3000 mile trip with a 42' fifth wheel on a 2016 Chevrolet single rear wheel short bed 3500HD, I will say they made a difference. They took some of the bounce and the side to side rocking out of the truck. I would definitely put them on my next truck as well. 667565

Still good. The right solution is a dually with heavier springs and more stability from 4 tires, but that is not in the budget.

Very happy with my timbrens and quick shipping. Added these to a 2013 2500HD 4X4. Quick and simple to install. improved ride quality and takes the squat out when pulling a gooseneck trailer. Very happy and would recommend to anyone wanting to improve quality of ride height. 493335

  • Comparing Front Timbren and SumoSprings for a 2002 Ford F-53 Chassis
    When comparing the ride quality between the Timbren # TFFF53B and SumoSpring # SSF-172-40-2 I recommend going with the SumoSprings. Although Timbren is a very solid product, the SumoSprings have been proven to have more of a forgiving support over the Timbrens. This is supported by great reviews and feedback from customers.

    The biggest difference between the two for your 2019 Thor ACE 30.2 motorhome, and the reason why I highly recommend the SumoSprings over the Timbren, is what each product is constructed from. The Timbrens are made from a strong, rigid rubber while the SumoSprings are made from microcellular urethane. This is important because it means the SumoSprings will compress more gently, while the Timbrens are known to give a much stiffer ride. The front axle and rear axle fits for your 2019 Thor...

  • Choosing Between SumoSprings or Timbren for 2013 Fleetwood Storm 32BH
    Although either the # SSR-187-40-1 Sumo Spring or the Timbren # TFRF53A would be a great choice, the Timbren Aeon spring is actually rated higher at 8600 lbs, versus 2600 lbs for the Sumo Springs alternative. Neither of these options will come into play unless the factory suspension gets compressed. If ride quality is the more important consideration, the Sumo Springs option is what I'd recommend as they' give a more supple ride. If reducing roll in the corners is foremost in your mind,...

This will help with the stability of your coach and act as a shock absorber as well. They help reduce body roll and compensates for off center loads as each spring works independently.
