Although image shows effects of sag on a rear axle under a heavy load, similar improvements will be made when the Timbren SES is installed on the front end.

Just as the rear of your truck sags when you're carrying a heavy load, the front of the vehicle will sag under the burden of heavy equipment such as a snow plow. In this case, the front axle is handling not only the weight of the equipment, but more of the vehicle's weight, as well. 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 the vehicle level and improve your driving experience.


Install diagrams of Timbren hollow rubber springs

The Timbren system has a vehicle-specific bracket that will be bolted onto each frame rail above the front axle. Hollow rubber springs are bolted to the bottom of the bracket, hanging down so that the bottom of the spring touches the axle. Because the spring is already making contact, it is working at once to cushion and support the vehicle's existing 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 the vehicle 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 the 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.

A snowplow mounted to the front of the truck will require extra suspension support for the front axle.

Timbren's Suspension Enhancement System will raise the front of the end of the vehicle when heavy equipment, such as a plow, is attached. Headlight beams will point in the right direction and your tires will wear much less. If the plow is off center or has an extension, the hollow rubber 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.


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 micro-cellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Feature Review Timbren Suspension Enhancement System-TFF550SDH

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Timbren Severe Service Front Suspension Enhancement System. Now, this is a custom fit part, this kit here is designed to fit the 2005 and newer Ford F-350, F-450, and F-550 cab and chassis models, and on a custom fit part like this one, I do recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now, this kit here will improve your suspension, your handling, and the safety on your vehicle. This one, as we mentioned, is a Severe Service kit, and these are recommended when you're using like a snowplow or heavy aftermarket accessories like a steel bumper on the front of your vehicle. Basically, any application that requires maximum stability, meaning reducing roll and sway, calls for a Severe Service upgrade.

You can also get the Severe Service option for the rear of your vehicle also. Now, most rubber springs used on trucks are double convoluted, providing a perfect blend of capacity and ride quality, but the rubber springs that are used on these Severe Service kits are single convoluted. The single convoluted springs are shorter, wider, they're designed to resist weight more aggressively, and the result is reduced ride quality in exchange for more stability. These will work independently side to side to help compensate for off-center loads, and they'll even reduce body roll when you're swerving or turning corners. They do also act as shock absorbers, taking the brunt of bumps in rough roads, helps extend the life of your vehicle's suspension.

This kit will include everything laid out here on the table, the two Aeon rubber springs, the spacers, the vehicle specific brackets, and the hardware for a nice simple installation. Does come with a nice set of instructions that'll describe how this goes together. Now, these do replace your axle bump stops that are on the truck, and there's no drilling required. Capacity on this is 11,000 pounds. Now, thing you need to remember is even though you're increasing the spring rate by adding this upgrade, this does not increase the gross vehicle weight rating of your vehicle, so you do wanna make sure not to exceed the manufacturer's recommended weight limit, and this kit is designed to work with a suspension system that is in good working order.

But that should do it for the review on this Timbren Severe Service Front Suspension Enhancement System.

Works great. Was using air bags, but find these much easier and less hassle.

2020 Ford F-450 Cab and Chassis



by:

Easy install took about 20 minutes on my 2017 Ram 3500 SRW. Had about 1/2 inch clearance as recommended. Loaded up my 5th wheel (2350 hitch weight) and about 200 lbs of gear in the bed. Just got back from a 800 mile camping trip through mountains of TN. You can really feel the difference around those sharp corners and uneven surfaces. The truck felt firm and controlled not hard and jarring as some have mentioned. Going over those overpasses with the wonderfully smooth (Not) joists was greatly improved. The truck would squat and rebound again, with a firm controlled response. Driving without a load felt the same as before without them. I would highly recommend these! Ordering from etrailer continues to be my go to option!



by:

The product came very fast. I already installed it the same day on my 2009 Dodge Ram pickup. It looks like it should do a fantastic job. I'll know better when I hitch up my travel trailer.



by:

Took about 45 minutes to install. But that was 2 trips into the house cause my deep drive sockets were buried. F-350 gasser with 8’ box, Fiberglas cap, 200lb wooden storage drawers and estimated 400lbs in tools. I tow a 14k bumper pull dump that squats the truck. I installed the spacer with the timbrens and it sits on the original axle stop. Ride quality is unknown as I haven’t driven it yet.



by:

I bought the timbren SES 121474110. I am not really satisfied with how these helped my trucks towing stance. The truck tows the same. I carry an in bed tank with 50 gallons of fuel in addition to the 35 gallon fuel tank from factory. The truck rides the timbrens the whole time. Thats okay, my problem is that the truck squats the same amount with these when I hook up my car trailer. The truck still goes straight down to the load leaves (pretty heavily squatted) the same as before. Did I get a light duty version? dont feel these meet the 6,000 Ibs capaticy as advertized. I think I should have gotten air bags. The product was well made. so they still get 2 stars. Just not what I thought it should have been.



by:

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:

Installation was a breeze, removed old bump stops installed Timbrens in about 30 minutes. Haven’t put a load on them yet so I’ll update later. Installed on a 2008 Silverado 2500HD..



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:

Out of the box fit !!
Only issue I had
was keeping the wedge from moving during installation



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:

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:

After successfully using air shocks with on board compressor on our 2001 F250 for years, I almost automatically put the same setup on our new 2022 F250. We tow an 11k lbs travel trailer. Then I read reviews on Timbren Suspension Solution & thought, worse case I’ll end up with both solutions. After spending 20 minutes installing Timbren and towing the trailer a few miles, it became obvious I didn’t need air shocks, or anything else. The truck & trailer drive as one. Our rig is level and rides great. When the trailer is unhitched, the Timbren’s aren’t engaged - just a normal F250 ride.



by:

The Timbren rear suspension bump stops are the best by far. I installed this unit on a 3rd gen Toyota Tacoma which became an essential item for safety towing purposes.

The main reason for purchasing this product was for aided support for towing. This is essential for those who tow boats, tear drop trailers or medium sized campers.

The stock bump stops are relatively small in size which is standard for other vehicle manufacturers however Timbren's bump stop are made with such high quality material and craftsmanship.

This also helps in preventing in stressing the front suspension from becoming raised which can affect your steering when your towing. The Timbren bump stops also helps in preventing your rear suspension from the "sagging effect" which can cause stress to your tires.

I recommend that when you install the bumps stops, check the lugs every quarter or depending on frequent you tow, to include tightening the lugs with a torque wrench to ensure it's torue specification(s).

This product has given me peace of mind when traveling long distances and when camping off the grid. Timbren also has good customer support service however etrailer has paramount customer service as well.



by:

I’d seen similar products rated in the 4,000 lb ratings but I went with these. I’m not a mechanic but I removed the factory bump stops and installed both these in 30 minutes or less. I used my rolling jack and lifted from the drop hitch and easily removed the old ones and soapy water and 1/4 twist and these were on. Placed a block of wood in the space between these coils and lowered the jacks then pressed it with my tractor to confirm full engagement. I carry a lot of tools on a 2020 Chevy 2500 I do feel a bit of butt bounce on large bumps but other than that I’m very pleased.

Caution,these parts did not fit my 2008 Suburban 1500 as advertised. Also FYI, Amazon also says they will fit. After some alterations I got them to finally seat. Tha original bump stops have a groove cut into them about a 1/2" from the top to accept 6 pertrusions that are stamped in the bump stop cup. After several attempts to press the Timbrens into place they wanted to pop out or were very easily removed with little pressure.I ended up cutting in 6 notches with a utility knife. Photos attached. I used markings on the old bump stops to determine spacing. I marked the Timbren with chalk to illustrate approximately where I notched them.Caution, cutting hard rubber with a utility knife is dangerous if you are not used to using a utility knife. I believe Timbren makes a spacer with a groove cut in them. That would make installation a lot easier. I cannot fault etrailer because they probably are following Timbren specks. Also I am not sure all Suburbans of this era have the same bump stop cup. I would recommend checking your old bump stops before ordering. Hope this helps.



by:

Worthwhile investment. Easy and simple install. Adds stability to keep RV from wanting to tip over. Same as adding a torsion bar. Needed to jack up the body, to install and after installation, Timbrens are engaged with no clearance either on top or bottom. I would purchase again if needed.



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:

I just installed Timbrens in our 2024 Sequoia Capstone. It has 22" wheels so I was able to slide under the rear axel and swap out the factory parts without jacking or removing the the wheels. It took me about 20 minutes to do both sides. With no load I can fit almost two fingers between the axel and the bottom of the Timbren. I tow a 29' boat that has about 600-700 lbs of tounge weight. The Sequoia sits pretty level and rides great. I had a 2010 Sequoia before this one that I installed manual rear coil airbags that worked well. I like the Timbrens as there is no pumping every time I tow.



by:

I was able to pull my RV with 550lbs tongue weight without the excessive rear end squat. I did notice however that I can feel them engage during normal unloaded driving when I drive over dumpy parts of a road where before there was more spring travel. It’s not bad but a stock 97 f150 does have a smooth ride. These will take some not, all of that away. But the up side is well worth limited ride change.



by:

Package had been torn open, and the box was empty except for bolts. I have cameras and they were not stolen from my house, so they must have come up missing during the delivery process



by:

The last two things I bought from E-trailer looked like they were used. This one at least had all of the fasteners, although they didn’t seem to be the ones in the directions. These had Allen heads and I had to buy a socket that had an Allen key. The directions included aren’t very clear. I had to find some YouTube videos to make sense of the install unloaded I can’t tell any difference, which is great. Hoping this fixes my backend squat with the boat trailer attached which is so severe I can’t flip down the trailer jack. Fingers crossed. Get a jack under the hitch and really unload the axle from the frame. Once I got enough clearance it was truly a 30 minute job.



by:

A year after installing these and many miles old towing I heartily recommend them. F150 is totally level while towing a 7000 lb fifth wheel. Great economical solution to sag!

  • Suspension Enhancement for 2020 Entegra Odyssey 26D
    We have a Timbren solution for the front and rear suspension of your 2020 Entegra Odyssey 26D but we do not have a SumoSpring kit that fits at this time. The Timbrens are a very similar design and would work well to improve suspension support and stability. So for that you'd want the part # TFRSDE for the rear and # TFF550SDH for the front.
