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.

The order with Will at etrailer was great. He was very helpful and knowledgeable, Installation was not easy but not too bad, The hardest part was removing the factory pieces I removed them from below which was a blind nut removal operation. This is on a 2017 Mercedes Sprinter motorhome. After removal of the factory pieces I discovered that access is much easier on top between the tire and the mud flap, I turned the front wheels inward and they didn't have to be removed. The front of the motorhome had to be raised quite a bit to get the Timbren piece jnserted. Also I learned to tighten the bolt and nut in the Timbren bumper as much as possible before installation because there is no access to the bolt head when tightening the top nut to keep the bolt from turning, preventing tightening the nut.

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



by:
Mercedes-Benz

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.



by:
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 know it will be lovely when loaded or the trailer on. However,it rides like a wagon empty with brand new premium shocks and struts empty. Thud thud thud. You really cannot feel the shocks or suspension. Found exact same item plentiful for 60 bucks on eBay after I bought these for 250. I may cut these in half or put air bag on. I do not like the ride empty. No hard feelings. It is a good product maybe just not for me.



by:

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.



by:

Was able to install these with a 15mm flex head ratchet wrench and lifted the rear of the truck to make it easier. 30 minutes to take off 4 nuts and put em back on. 2 minutes assembling the timbrens with the added spacer. I have a f350 with a salter and plow. Loaded with salt the lights shoot up and in the snow ?? it’s like hitting hyper drive and you’re blinded. These helped big time. Very happy so far.



by:

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.



by:

The pro: The longer, heavier bump stops worked great when hauling my mustang home from Chicago. The truck stayed level and handled great.
The con: I had to remove the bump stops for everyday use. They limited my suspension travel causing a stiffer ride.

  • 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.

  • Best Way to Control Sway on a 2018 Thor Motor Coach Gemini 24TX
    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. The rear anti-sway bar is actually going to do more for you in regards to sway control compared to a steering stabilizer. The rear anti-sway bars are also typically the most beneficial enhancement that you can...

  • 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.
