An example of sag on a truck's rear axle under a heavy load. The Timbren Suspension Enhancement System levels the vehicle.

Whether you're hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the truck's weight, as well. 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 has a custom-fit bracket that will be 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, one inch 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 the truck level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's 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 the truck. 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. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.


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 because the rubber has more travel.

It was very easy to order this item from Etrailer. The item was delivered earlier than expected in strong packaging. Now for the Springs. I chose these because of the no drill install and reading a lot of reviews. I placed the springs on the rear axle of my 2018 Georgetown GT5 on the Ford F53 20,500lb chassis. It took around 20 min on my back but was easier than expected and I am 74. I have driven 1200 miles on the springs and I am more than happy with them, worth every penny. Side wind and passing trucks was almost eliminated, almost. 643899

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. 804123

The vent covers and Timbren products were shipped quickly and everything I needed was included. They were very easy to install, 3 covers done in 20 minutes. Timbren suspension products I chose because of ease of installation, no additional drilling, no taking the tires off. These did take some time but we’ll worth the effort, handling greatly improved. Also added Safe-T-Plus steering. 804120

Installed Timbren on my 2007 coachman Mirada , Ford F 53 chassis (2005) with a panhard bar , tight fit with the bar brackets. I spaced the Timbren away from the frame with large flat washers which gave a more comfortable clearance to brackets. Some brake line and vent hose adjustments and a hole to drill for a Factory electrical part mount . I gained 1 1/4 “ trailer hitch height , very satisfied. 796840

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. 756628

Just installed the Timbren suspension stabilizers on the rear of my Newmar Canyon Star 3911 motor-home. The installation was easy and simple. As the video showed, just remove the old bump stops and install the Timbren's. They are significantly larger than the stock bump stops. After having installed the Sumo Springs on the front and the Timbrens on the rear, the ride is so much better. No more swaying back and forth when a big truck passes or a crosswind. I highly recommend this combination since there is no drilling into the frame of the motor home and you do not have to remove the tires either. 695925

Review from a similar Aeon Spring System in Vehicle Suspension


I ordered timbrens for the front and rear of my chevy 2500. I have a 2000 lb truck camper and I wanted something to help carry the load a little better. I had no idea that my front bump stops had worn away to almost nothing until I installed these. They have worn well and performed well so far. 628835

the timbren tdr3500ca were a very easy install on my 2018 ram drw 4x4. The included spacers were needed and left about 1/2 inch clearance. empty ride is same. Will load arctic fox 990 soon and expect great results. I elected not to reinstall my air bags, when trading trucks. I also have upper stable loads and will not miss the air bags. ordering was easy and free shipping was fast. 612456

With my af 990 camper installed they are fantastic. More stable than my previous airbags and the ride is better than empty. Trouble free and no hassle. Install and forget. Very happy.

Ordered these from Etrailer.com and got them in three days. Super easy to install on Ram 3500. Didn't have to jack up truck. Assembled is 6.5" on Ram 3500, I had 7" to play with so plenty of room. Haven't added a load yet as 5th wheel is on order. Looking forward to it. 609612

Took longer to take it out of the box than to install them on my ram 1500... dish soap and twist and upward pressure with both hands(if your tough enough) and “presto” the job is done. About 1 1/2” clearance (bottom of new bump stop to top of axel) when empty and a little over 1 3/4” drop with a 16’ enclosed trailer weighing 4400#s totally loaded. Rides great and stabilized the truck. 771782

Review from a similar Aeon Spring System in Vehicle Suspension


I had bought these timbrens and the weight safe hitch with the 8” drop from etrailer. I was quite please by both products. Installation of the timbrens was very easy, only took 30-40 minutes to change out bump stops in my garage.I hauled a Uhaul trailer with a Jeep over 300 miles, with no issues. The timbrens worked great, no issues with the rife. And I really like the weight safe hitch. I recommend checking out these two products from etrailer. Thanks etrailer. 642864

I purchased these to help with the squat on my F-150 when towing my 32--foot travel trailer. I need to tweak the setup on my WDH, but otherwise am very pleased. Without the trailer, you don't even know they're there. 558730

Review from a similar Aeon Spring System in Vehicle Suspension


I bought these for a 2012 GMC 2500 Duramax. The installation for these was much easier than I anticipated (I can't say the same for the front suspension system.) Just lift up your truck, pry out the stock bumper stops, line up the Timbren springs with a 2x4 underneath, and lower the truck. The weight of the bed/frame is enough to get the Timbren spring to seat correctly. This took me less than 10 minutes. Ride quality seems to have improved as big bumps on the road are less rough. These keep the truck from sagging underneath the weight from a trailer, too, though I didn't have much problem with that to begin. Overall, I like this addition. Easy. 48427

The product worked great and was very easy to install. The delivery took a little bit longer than I had hoped for, however everything worked out fine. I would highly recommend this product for towing, or if you're putting your vehicle under any kind of a load. E Trailer was fantastic! 561603

    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...

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.

  • Suspension Enhancement to Reduce Sag and Roll on a 2000 Hurricane Motorhome Ford F53 Chassis
    First, if your RV is sagging because the suspension is worn, you will need to have the suspension fixed before adding springs.

Once you are sure your suspension is in good working order I recommend using a system with a higher capacity. For a higher capacity system, 16K to 22K, use # SSR-181-54-1. This system will reduce sag and help reduce side to side roll. Using...
