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.

I just completed installation today. Directions could have been a little clearer but once I looked at it no problem.
Test drove about 3 miles and turned back one thing I noticed right away was ride was smoother.



by:

Easy to install, and they dramatically improved the ride and stability. I wish I added these 30 years ago when My motor home was new

So far, so good. No issues.

Made a HUGE difference in ride on our 2021 Sunseeker.



by:

Haven’t put them on yet.
Happy with the
service and polite, caring, your people have shown thru this process. Made me feel like they knew me and I had been a customer for years.
Thanks for caring
Robert



by:

Timbren is the way to go. Progressive resistance unlike sumo and durable. Customer service is top notch. This is the first front set I have ever used.
E450 2022 Sunseeker 2850.
Only thing is, you use the nut welded to the frame and have to use a universal joint to tighten.

I’ve personally installed 5 sets of them on pick up trucks



by:

Product looks very well made and etrailer sent it very quickly, via standard rate no less! Package came w no damage. It’s always a pleasure buying from e-trailer. Now I have to just install it!

Easy to install Great helper for springs



by:

They work great. They really helped my vans front end.



by:

Very easy to install, maybe 15 minutes for both
On the initial drive test the front end definitely feels more positive and less sway. Will continue this review after loading up and hitting the road

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:

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.



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:

I am so glad I bought these for my truck. I was able to install them myself using a jack and jackstands. The ride is bit rougher now; but the suspension is totally awesome compared to before. I am able to haul a bit more weight when needed.



by:

very good product ,received just in time and fit perfectly on my GMC savana 2000 .Be sure to clean the two receptacle thats help.
très bon produit , reçu dans les délais et s'ajuste parfaitement . Assurez-vous de nettoyer le receptacle cela facilite l'installation.



by:

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



by:

Pros: Cheaper and easier to install than airbags, do the job when load is enough to compress the shock, with added weight or towing, then it stiffens the rear very nicely.
Cons: Doesn't do anything until there is 2-3cm of compressed shock. It sits above the contact point, doesn't touch. Under normal driving, there is no benefit/improved stiffness/anti sway in rear or a leveling of the factory rear sag in a 2022 or newer Toyota Tundra.
If had it to do over, would have put some kind of spacer in between product and upper included bracket, the supplied bolt is long enough to accommodate, to eliminate the gap, and lift the rear 1-2 cm. Should do it anyway, maybe when swapping to summer wheels next month.

  • Recommended Front Suspension Enhancement for a 2018 Thor Quantum Motorhome RC25
    The Timbren Front Suspension Enhancement System part # TFEF350 is rated at 3,000 lbs and the Timbren Front Suspension Enhancement System part # TFEF350UH is rated at 6,000 lbs. I was able to call the manufacturer to confirm this. They will both fit your 2018 Thor Quantum Motorhome RC25 on a Ford E-450 chassis but I recommend using the Timbren Front Suspension Enhancement System part # TFEF350UH as it will be better suited for your motorhome.

  • Which Timbren is Best Choice for 2019 Ford E-Series Cutaway
    Unfortunately the most comfortable ride can be subjective. My suggestion is that if at present time you have hard contact with factory axle bump stops on frame and a very rough or unstable ride in turns, I would definitely select the Timbren Front Suspension Enhancement System, # TFEF350UH. If the current ride does not typically "bottom out" except for very rougher patches of road, then I would select the Timbren Front Suspension Enhancement System, # TFEF350.

    I'll start off by saying that currently there are no SumoSprings that have been confirmed to fit on the 2021 Thor Chateau 27R, so that's why there are not any showing up in our fit guide for your coach. However, the Timbren # TFEF350UH and # TFERSDLB are a good choice that will provide the same functionality and perform comparably. The Timbrens are also a progressively strengthening spring like the Sumo Springs in that they get stiffer as loads are applied to them; they also provide the...

  • Will Timbren Front and Rear Suspension Enhancement Help With Sag and Sway on 2005 Ford E-150
    The addition of the Timbren Front # TFEF350 and Rear # TFER15087 suspension enhancement system will definitely help with sag and sway on your 2005 E-150. These work progressively so resistance increases depending on the load. They will also work independently to support both sides of the vehicle and prevent sway and improve handling. In addition to the support they provide they will also help to extend the life of your vehicle suspension. Both the front and rear have a 3,000 lb capacity...

  • Recommended Timbren Suspension Enhancements For A 1992 Fleetwood Jamboree Searcher Class C Motorhome
    Adding in some lighter capacity enhancements can help cushion the ride as well as reduce sag and swaying. For your E-350 chassis you'll need the Timbren Front Suspension Enhancement System # TFEF350 and Timbren Rear Suspension Enhancement System # TFER35092B. These both easily bolt up in the same way as your factory bump stops so it should be a very easily swap out for you.

  • Front Hitch and Sway Bar/Suspension Enhancement for a 1995 Ford E-350 Van
    There's no reason you couldn't install the Front Sway Bar part # RM-1139-115 as well as the front hitch part # 65001 at the same time on your 1995 E-350 Ford Van. I will say that typically with a front hitch people want front suspension enhancement to help with sag from hitch accessories like plows. A Timbren system part # TFEF350 might be a better solution if this is the case for you. This system will provide you with additional suspension support when the hitch has a load on it and won't...
