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.

Called to return them and want me to pay 27.00 shipping and stated in email that was sent to me I couldn’t return if installed. I’m not understanding this ? Do not buy !

These are the best add on suspension helpers I have ever had on a pick up. I put 2 yards of compost in the back of my 1/2 ton Silverado W/T long bed and it rode level back to the house. These control sag when you drop on a trailer loaded or not.

  • Suspension Enhancement For 2023 Mercedes Sprinter 3500xd AWD 4WD
    Hey Doug, our fitguide is sometimes a bit confusing, but the Timbren Rear Suspension Enhancement System # TMBRSP35A you were looking at fits the 2023 Mercedes Sprinter 3500xd AWD/4WD (fits 2wd or 4wd/AWD) if it is a motorhome. If it is not a motorhome, then you'll want the B version which is # TMBRSP35B (2wd or 4wd/AWD).

    Hey Rick, thanks for the information! It looks like your 2023 Leisure Travel Van 24RL is a 2WD so that excludes the options for rear SumoSprings. Instead, I recommend the Timbren Rear Suspension Enhancement System item # TMBRSP35A. These are designed to stabilize your rear suspension and help you with that top heavy sway feeling. For the front end, you'll be able to use the SumoSprings Solo Custom Helper Springs item # SSF-106-47, you were looking at. These replace your existing bump...

  • What Suspension Enhancement can I Add to My 2024 Mercedes-Benz Sprinter 3500 for Sway?
    Hello Mara, Happy to clarify the difference! The # TMBRSP35B is rated for 11K, while the # TMBRSP35A is rated for 7K. Timbrens are a great option, especially for someone who consistently hauls a heavy load. However, if you’re not carrying that kind of weight all the time, they can make your ride feel a bit harsh when unloaded. If you're looking for something similar to Timbrens but with a smoother, more forgiving ride when not under load, I’d recommend going with SumoSprings. Here are...

  • Suspension Enhancement Recommendation for 2018 Mercedes-Benz Sprinter 3500 Motorhome
    For your motorhome built on a 2018 Mercedes-Benz Sprinter 3500 we have great suspension enhancement kits available but none that use air bags. Instead the kit I would recommend is the SumoSprings kit part # SSF-106-47 which is similar to the Timbren but won't be as harsh of a ride. This will help brace the rear suspension which will help the vehicle ride better and not have quite as much body roll. If you haven't driven the motorhome yet I'd recommend doing so first. There's no rule that...

    The Timbren Vehicle Suspension, part # TMBRSP35A, is the correct suspension enhancement system for your 2012 Mercedes-Benz Sprinter motorhome. This system helps reduce body roll and increases stability, as well as reducing sag at the rear of your Sprinter. The # TMBRSP35B is designed to be used on Van or Cab and Chassis models, and is not a fit for your Class B motorhome. If you need help with the front of your Sprinter I recommend part # TMBFSP35.

    As long as the shocks on your 2013 Mercedes-Benz Sprinter 3500 are still in good shape, there is no reason to replace them. However if they are worn out you will notice quite a difference once the replacements are installed.

If you have not already decided on which sway bar and SumoSprings you plan on ordering I recommend the Roadmaster Rear...

  • Suspension Enhancement Recommendations for 2006 Dodge Sprinter Ambulances
    Because an ambulance will have a lot of equipment and in it and the the weight of people, the stock suspension will be compressed already. This can lead to the rough ride you described. Adding a Timbren system like # TMBRSP25 for a 2006 Dodge Sprinter 2500 or # TMBRSP35 for a 3500 will reduce the stress on the factory suspension and absorb road shock and reduce roll. This will provide a much better ride. Both sets have a capacity of 8,600 pounds and are made of rubber. I have included...

  • Recommended Suspension Enhancement for 2012 Winnebago 24M On Mercedes-Benz Sprinter 3500 Chassis
    For your 2012 Winnebago 24M on Mercedes Benz Sprinter 3500 chassis, I recommend the Timbren system consisting of the Timbren Rear Suspension Enhancement System # TMBRSP35A and # TMBFSP35. Timbren is a stiffer support spring than the SumoSprings, so you will feel the support sooner for your motorhome. These springs become more rigid as weigh it added and they work independently for off-center loads and to reduce body roll. Especially the 7,000 lb rear springs will give more support...

  • Recommendation for Reducing Rock On 2016 Forest River Sunseeker Mercedes Chassis Leaving Driveway
    I recommend adding the SumoSprings Solo Custom Helper Springs # SSR-338-47 to your 2016 Forest River Sunseeker on the Mercedes 3500 RV cutaway chassis. These are a progressive rate spring that will help to absorb the rocking when pulling out of the driveway. The Timbren Springs # TMBRSP35A are a much harder rubber spring and will lead to more shock/bounce than absorbing the the compression.

    Hello Viacheslav, thanks for getting in touch. We do offer suspension enhancement for the 2023 Mercedes-Benz Sprinter 3500, but I am afraid there are no air suspension options.

    It's a very common misconception that suspension products like the SumoSprings, air bags, or Timbrens # TMBRSP35A will increase the capacity of a vehicle or RV. Nothing will increase the load capacity since there are numerous other factors that play into the load capacity, such as the frame, tires, and many other components. You'll see this a ton with flatbed trailers and it ends up bending or cracking the frame or blowing out the tires so you do not want to risk your safety or the safety...
