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.

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.

Video Transcript for A Closer Look at the Timbren Front Suspension Enhancement System-T44FR

Hi everyone. Aiden here with etrailer. Today we're gonna be taking a look at the Timbren Front Suspension Enhancement System. This is going to be an upgraded bump stop for the front end of your vehicle, whether it be a car like the 4Runner here or a motor home. These are gonna come in a variety of different kits and fits with different capacities and help stabilize the front end of your vehicle. Let's check it out.

So why would you be looking for something on the front end of the suspension enhancement side A lot of people are pretty familiar with airbags on the rear axle, and a lot of those suspension enhancement components are used in towing applications or maybe truck beds where you've got really heavy loads in the bed and you need extra support at the back of the vehicle. Now what the front end can do is stabilize that front end, if you do have something like a front mounted hitch, maybe a plow on a truck, or on a larger vehicle or even a smaller vehicle like this, it does help stabilize body roll a lot because these are going to be a lot beefier than the factory suspension and the factory bump stops, that is, and help limit that side to side movement as we're taking turns or driving down in like really windy conditions on the highway. So this will give a significant upgrade for those applications. As far as the construction for these goes it's going to be a hollow Aeon rubber material with a progressive spring rate. Now, what the progressive spring rate means is the more this compresses, the more pressure it has, the more it's going to work at returning the vehicle to its natural position.

So it's just going to resist more and more as it gets further compressed. As for the installation process, this particular one that I've been holding is for the 4Runner, and this one is a very basic kit. It really just has a threaded end with a bolt and a plate on the inside, but this just spreads into a factory weld done on the 4Runner. Very straightforward install. But for all the other different fits and kits, those are gonna have custom brackets and their own hardware that come with it.

So no matter what one you end up going with, if it's a fit for your vehicle, it's going to be custom fit. So the installation should be just a straightforward bolt on process. Now obviously that can vary depending on the kit and what vehicle you're putting it on, especially on the motor home side of things. But for the most part, you should be able to have a very straightforward install process with any of these kits you pick out. And to make sure you find the right kit for you, be sure to enter your vehicle information into our fit guide and use that to narrow down for the custom fit options available for your vehicle.

If you're considering some front suspension enhancement, I do think that these bump stops from Timbren are a really solid option. From the testing we did in installation on our 4Runner, they performed great. They reduced a ton of the body roll and really helped when we're going over speed bumps and just aggressive driving conditions where we need that extra support. Whether you've got a truck with a plow on it, or a motor home that you're trying to reduce body roll on, something like this can be be a huge help and it's a very straightforward solution. But that'll do it for a look at the Timbren Front Suspension Enhancement System Bump Stops. Thanks for watching.

Timbren Front Suspension Enhancement System - TFXF1004

Average Customer Rating:  4.7 out of 5 stars   (6370 Customer Reviews)

1,000-lb Capacity. Great for trucks with plows, these front hollow rubber springs help to stabilize and level your vehicle. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.

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 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:

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:

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:

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:

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!



by:

Super simple to install. My 2018 f150xl would almost hit the bump stops when I hooked up my 7x16 enclosed trailer. Now, it almost rides level. Much safer feeling ride also. Without the trailer, it rides like an unloaded dump truck. It is what it is. I'm happy with them.



by:

Received the Timbren SES kit in today's mail around 11:30AM, already installed on my 2024 F-150 pickup's rear differential before 3:00PM same day. Like always etrailer's fast delivery time and product info with installation video on your website are very helpful. 1st photo OEM bump-stop, 2nd photo OEM bump-stop removed, 3rd & 4th photo Timbren SES kit installed.



by:

Absolutely fantastic! So easy to install. These have completely change the ride quality while hauling our truck camper. The truck now rides better loaded than unloaded. The gap under the SES is small, less than an inch. So unloaded ride is a bit ruff since it bottoms out super easy on the smallest bump.
But if I wanted to I could take them off since they go on so easy.
I still wouldn’t pass up having these. I can’t say enough how great they are. And I ordered a used set which were in new condition. Less money, same awesome outcome. Can’t go wrong!



by:

The Timbren SES (Bump Stop) replacement for the 3rd Gen Sequoia is a simple and effetive solution to reduce vehicle sag when trailering heavy loads. You definately want to use the included spacer as the pics will show I still had 2 finger clearance above the axle to allow for OEM suspension travel. I pulled my 29ft boat back to back with / without the Timbren bump stops for a ride quality test. Without the bump stops, my 2024 Sequoia rear end was crushed, resulting in a rough ride and poor handling characteristics. With the Timbern bump stops, the rear sag was reduced signifincantly, and the vehicle drove much better. YES, you will feel and occasional bottom out feeling on abrupt G-out dips... But it is no worse than without the Timberns as the stock springs were crushed. My daily drive feels exactly the same as I have the perfect gap between the Timbren bump stop and the axle allowing the OEM suspension to float over road surface without engaging the bump stops. VERDICT: Time will tell with varied passenger loads, speeds, road surface bumps etc., but my initial impression is 7 out of 10. Ultimately, I would prefer air bags, and may install them along with the Timbrens whih I can swap back to the oem bump stop in less than 15 minutes. NOTE: I was able to install the Timbren bump stops without going under the Sequoia. I simply raised the vehicle frame aprox. 4" withoug picking up the rear tire. This gave me adequate room to reach in over the tire and remove the 3 12MM bolts holding the OEM bump stop in place with a 3/8" ratchet and a 4" extension. Then, I put the Timbren bump stop in place and lightly threaded the upper bolt to hold in place. After installing the two lower bolts and smart torquing, then you tighten the top bolt. This allows the bracket to seat against the frame fully as the top bolt hole is slotted to allow movement druing install. Pics will show spacers installed above the bump stops, Installed bump stops unloaded with 2 finger gap, spacers loaded with 750 lbs of tongue weight, and lastly, will show Sequoia stance while loaded. NOTE: The last picture will show my Sequoia loaded WITHOUT the Timbren SES (Bump Stops) and the vehicle is sagging heavily.



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

Jesse M gave me expert advice and answered all my questions regarding the Timbren rear suspension enhancement system. I ordered the Timbrens and it took me a little over half an hour to install myself. I absolutely love the way the Timbrens leveled my sagging truck and greatly improved the stability of my ride. I carry a 2003 Northstar tc1000 pop-up camper on my 8ft bed. I highly recommend the Timbren rear suspension enhancement system. I attached a before and after photo.
