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.

Should of put fronts on same time.

Very happy with upgrade, really need both front and back.Have sold the Class C.Now have a Winnebago Paseo.Installed on rear already.Wish I could also find a timbre for the front.

2016 Mercedes-Benz Sprinter

This enhancement replaced the OEM for a 2016 (new) Mercedes Sprinter 3500 Class B+ camping chassis. OEM was OK (good enough), but the Timberlin enhancement reduced front end bounce and sway on rough roads significantly -- noticeably. (Rear Timberlin suspension enhancements were installed prior to delivery/acceptance from dealer). The Timberlin shock arrestors are three times larger than OEM. Cost to install by experienced mechanic -- $65 (less than an hour). We're happy with it. (The Sprinter has an OEM rear anti sway bar, it could also use a front anti-sway bar as well when the vehicle is used for long trips.) Having said all that, I favor the Sprinter over other Class C and B+ chassis without these modifications.

11,000 miles would not drive without both front and rear Timberlin suspension

They work as described.

2006 Winnebago View

The installation took about a half hour on our 2006 Winnebago View. I did not need to remove the tires, just jacked it up enough to unload the suspension a bit.
The upgrades have quieted down the front suspension both reducing hard suspension hits and body lean. The front of the View is definitely more settled.
Pros: Simplicity, and ease of install. measurable difference in RV suspension performance.
Cons: expensive for what they are. The long bolts used do not inspire confidence.


I installed these on my 2015 Navion motorhome. It was very easy and only took about an hour. They did more than I expected. The ride is much better and a small shimmy that could be felt in the steering wheel at about 65 is gone. I would recommend these for all MB motorhomes.

2016 Mercedes-Benz Sprinter 3500

Installation was simple and easy. The video was helpful.


Service was good. Product was good. A little pricey but overall good experience.


Product does what it is intended to do. Although with my application, installation was harder than needed. Poor design for installation purposes.


It really added the support that was ne eded


2005 Dodge Sprinter


Work Great!


Exactly what we needed



Review from a similar Timbren Aeon Spring System in Vehicle Suspension

About a 1/2 inch difference in gap at the bump stop perch but still within parameters. Truck sits perfect with trailer attached. Haven’t towed yet. After towing if they perform like they should will upgrade to a 5 star. Easy to install, definitely needed 2x4 and jack. 2011 Silverado ext cab with 30 ft Genisis 5th wheel.


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I have used Timberns on 2 other vehicles, a Toyota 4Runner and an S10 Blazer with out complaint.

I transport RVs as a contractor for an RV transport company. My truck is 2021 Ram 3500 crew cab, 6.7 diesel.

Because the weight of the units is different with each unit I haul I wanted an easy, no maintenance solution to maintain as level a ride as possible. I haul both bumper pull and 5th wheel units. In addition to the weight of the unit I'm hauling I can carry 110 gallons of fuel with both the factory fuel tank and my auxiliary tank. Additionally, there is the weight of my Curt 25K 5th wheel hitch, Curt 14K equalizer hitch and bars, and approximately 300 pounds in tools.

I don't have to worry about airbags not inflating. The suspension settles about an inch before making contact with the Timberns. Squat while loaded is negligible. The ride empty is the same as it was before installation. The ride loaded is smooth and controlled even when hitting large bumps at highway speeds.

Installation was simple and straightforward. It took me about a half hour.


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

They definitely support and did lift my 2014 toyota tundra up about 1.5 inches.
This application with my weight has trunk riding on the cushions all the time.
That has teavel and bounce issues that do make some driving situations interesting.
I may go ahead and replace with airbags but for now support things well!


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Makes my truck feel better while towing a 5th wheel camper, especially over expansion joints of the expressway.


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I think I will be very happy with the ride when I tow our fifth wheel, it definitely needed the extra support especially on rough roads.I chose not to use the spacers because I like the softer ride when the truck is unloaded.


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

The timbrens actually did what they were suppose to do. However, once I starter driving out west I notice the timbrens were riding on the axle which cause the speedometer to jump around depending on the road. I would recommend them if you are hauling or towing a camper or RV. I was going to contact etrailer about maybe removing a spacer for one set however the other set came as one unit. The bottom line is the Timbrens does stabilize your load for safe travels. I will be contacting etrailer soon to assist in correcting the problem...Road trip from Idaho,Colorado,Wyoming,and Utah were beautiful... Thank you etrailer


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I haven’t hooked up to the fifth wheel yet or else it might be a 5 star. Based on the 15 minute installation time and the price compared to air bags this appears to be a logical way to go. I will update this as I hook up and put a load on it.


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Haven’t had it on long, but so far so good. 1999 F350 dually. Bolted up nicely. Total job took 10 minutes. Have hauled two gooseneck loads of hay and truck drives SO much better. Nice and level. Money well spent so far.


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I have the timbren enhancement system on my 2020 canyon. I haul a trailer with Ranger that I pull about 250 miles to hunting camp. It tows great!


Review from a similar Timbren Aeon Spring System in Vehicle Suspension

The Timbren rear suspension enhancement system helped with the truck swaying side to side when the slide in camper is on the truck.
The photos show right and left rear with Timbren’s installed (2 photos), with slide in camper on the truck (2 photos) and when the camper was removed (2photos).

    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.

  • Comparing the Timbren # TMBFSP35 and SumoSprings # SSF-106-47 for a 2016 MB Sprinter 2500
    Out of the Timbren # TMBFSP35 and the SumoSprings # SSF-106-47 suspension enhancement systems I recommend the SumoSprings. Although they are very similar the SumoSprings provide more of a cushion and aren't as harsh or stiff as the Timbrens. This gives you a much more comfortable ride. Both options have a 1,000 lb weight capacity but please note that they will not raise the weight capacity of your 2016 Mercedes-Benz Sprinter 2500. They are only meant to help support a suspension system...

  • Are There SumoSprings That Fit a Four Winds Chateau Citation On Mercedes Benz Sprinter Chassis
    The Four Winds Chateau Citation is built on a Mercedes Benz Sprinter Chassis. I checked with SumoSprings and they don't offer any solutions for this chassis but I do have options from Timbren which are very similar to the SumoSprings. They have the Timbren Suspension Enhancement System part # TMBFSP35 for the front and part # TMBRSP25A for the rear so that is what I recommend using. The Timbrens actually provide more support than the SumoSprings.

    I do have options for you to help control sway on your 2018 Thor Motor Coach Gemini 24TX but they do not make a steering stabilizer for this chassis to my knowledge. Instead, I recommend adding a rear anti-sway bar like the Roadmaster Rear Anti-Sway Bar for Vans part # RM-1209-131.
