An example of sag on a vehicle's rear axle under a heavy load

Whether you're hauling heavy loads in your bed or cargo area or you're towing a trailer, you will often see the rear of your vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but also more of the vehicle's weight. Because less weight is on the front axle, the front tires are making less contact with the road. Overall 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.


Diagram of the Timbren spring installed

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits, 1" above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride that you are used to.


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 are hauling off-center loads.


An example of a trailers swaying

Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer, and this helps to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or a passing semi), because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.


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. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Ultimate Overview of the Timbren Suspension Enhancement System-T67KR

Hello neighbors, welcome back. I'm Steven here at etrailer.com. Today, you're joining me where we look at these Timbren Suspension Enhancement System for the rear axle. Now folks, this is a custom fit. It's gonna fit a 2023 through the current year Toyota Sequoias. Make sure you're using our fit guide at etrailer.com, top center of our page.

Enter the year, make, and model, and we'll get you the right parts the first time. And what these do, folks, if you're not familiar with them, they basically improve suspension and handling and overall safety by providing additional support when you need it the most to have the most comfortable smooth ride possible. And what they do is they allow your leaf spring ample movement while cushioning light loads, and they actually become more rigid or more stiff when they're compressed and you have more weight, which is gonna give you greater performance when you have those higher, heavier loads. It can help reduce sag, increased stability, they work independently side to side, and they also help compensate for off-center loads. They're gonna help you reduce body roll, like if you have to swerve or you turn a corner too tight.

And they also act as a basic shock absorber. They'll take a lot of the bumps, the rough road out of your ride, that kind of stuff. They will technically extend the life of your vehicle suspension because this will take most of that brunt of those constant bumps and that kind of stuff. Now what these are is they are two Aeon hollow rubber springs with custom brackets and spacers. I've got 'em just loosely put together here, but real simply, it's got a spacer block here.

You got the hollow rubber Aeon spring. There's a big washer in there that you saw, the nut goes underneath there. This gets bolted down into place. And then you use the existing hardware off of your factory bump stop that you removed, and this goes right back in place where that factory one came off of using the same hardware. So, pretty quick, easy install, no drilling whatsoever required.

It installs directly into your frame. You've already got pre-threaded holes there. This just simply replaces that. You put it right back in place where the old one was. Now this will give you a load level capacity of 6,000 pounds. Keep in mind, this is, again, just an enhancement. You're not adding any extra capacity to your vehicle. I think a lot of people get these kind of things and they think, "Oh, now I can haul 6,000 more pounds." That's not the case. Again, this is just a load leveling capacity. So it's helping your current factory suspension by giving it a little boost that it needs to keep everything level and that kind of thing. Well folks, that's gonna do it for our look today at this Timbren Suspension Enhancement System for your rear axle. I'm Steve here at etrailer.com. Thank you so much for your time. Thanks for watching. Have fun installing these.

Very fast delivery, good product, worked as advertised. It solves the sagging when my trailer is hitched.



by:

RV handles curves much better then before, more solid handling.



by:

So far everything is working. Just as I though. The only complaint I have is the wait time that it took (12) days from the order date to when I receive the item.



by:

These are exactly what my truck needed for the heavy loads I put into the bed.



by:

Really makes a difference when hauling a heavy gooseneck.



by:

I have not put any weight on it yet so that will come later. I have a 2007 G.M.C. 2500 H.D. and I pull a 40 foot Big Horn Traveler. What I want to talk about is the install. It was quick only took about a hour. Take the tire down and start. Had no problems it went just like the video showed. I did not use the big washer I didn't have enough room.I have about 1 inch of travel before they come in to play so ride is the same.



by:

Takes the sag out for a bargain, but not as good as real springs



by:

Super easy to install. After reading several reviews about this product and how folks went about installing, found that I just needed to remove just one of the U-Bolts and just barely loosened the second. Replaced both in about 30 minutes. Shipping was quick and was exactly what I ordered. Reviews were helpful and will definitely use etrailer again.



by:

Works great



by:

Bump stops I bought from you are way bigger and so much better than oem. Only took less than 30 minutes to install. It was very easy to install.



by:

great delivery time. I received them this afternoon and installed them in about an hour. thanks to the video that showed everything step by step. thanks for a great product. I think this is just what we needed to help haul our camper and pull our car hauler at the same time. thanks again



by:



by:

Great product, easy to put on. It took less than 45 minutes to put the new Timber butt stops on. Only thing I would request is to tape up the box they cam in, because by the time it travels to your location it’s beat to hell and back. Like the last time I ordered the ones for the front, all the parts were missing. Luckily this time all items were still in the box.



by:

Product fits as described. Will try out when I tow my travel trailer in a few weeks.



by:

Works good when pulling trailer take them out when not pulling for smoother ride only takes about 10 minutes



by:

The rear enhancement springs I ordered was exactly what I ordered. Thank you!!!



by:

Came just as advertised. Waiting to install. As an aside: You might want to make sure all box sides are securely taped as the USPO delivered the box with the un-taped side completely pulled away from the box and the suspension parts were pushing out of the box.



by:

Works great with my slide in camper easy install great product will do the front next



by:

Got them this morning as promised. Haven’t put them to the test yet but installation was a breeze, 30 to 45 minutes. That includes putting away the tools and washing my hands!



by:

Product arrived on time. Installation was easier than the video. Only took me 20 minutes.



by:

Works great. Helps to stabilize my large toy hauler behind my Ram Truck while traveling. My truck stays level with the heavy load.. Highly recommend.



by:

Every thing I got from you guys is all great . Thanks for checking !!



by:

super easy to install. I only used the jack to hold the u-bolts in place. Can't wait to put them to use!



by:

Easy install / part of the system I used to get the "Sway" out of my awfully heavy truck camper.



by:

Works great. Still looks like new after a year and we use it hard.

  • Rear Suspension Enhancement Kit that Fits 2024 Toyota Tacoma 4WD
    Hey John, so the 2024 Toyota Tacoma is a new designed truck so they currently only have a 2WD version fit with the part # F2410. For 23' the 4WD fit version is the # F2407 but it hasn't been carried over to the 24' models. Right now all we have is a Timbren fit with the part # T67KR which will do a great job reducing the sag.

  • How to Address a Sagging Issue w/ a 9,500 lbs Trailer and a Toyota Sequoia
    Hey Roy, that sounds like a fun trip! I recommend addressing your sagging issue with a weight distribution system not air bags. The best one for your trailer is going to be the Equal-i-zer Weight Distribution System w/ 4-Point Sway Control item # EQ37140ET. This system works with tongue weights ranging from 1,000 lbs - 1,400 lbs so it'll be perfect for your trailer when loaded. The Equal-i-zer item # EQ37140ET works by distributing the weight more evenly to the tow vehicle. This is how...

  • Roadactive Suspension Kit that Fits 2024 Toyota Tacoma
    Hey John, I checked with Roadactive (formerly Roadmaster) and they do have a kit that fits your 2024 Toyota Tacoma with the part # RAS4514-SAT but it seems like it doesn't fit the 24 models actually as the truck has coil suspension so instead the Timbren kit part # T67KR would be a great option.
