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.

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.

  • Weight of Timbren Springs for 2016 Lexus GX 460
    The Timbren Suspension Enhancement System # TTORSEQ that you referenced for the rear axle of your 2016 Lexus GX 460 weighs just about 6 pounds total (3 pounds per spring). The Front Timbren Suspension Enhancement System # TTOFTAC4A for your vehicle only weighs about 2 pounds in total. I have attached the installation instructions for these components that you can also take a look at.

  • Timbren Front & Rear Bumpstop Options for 2007 Toyota FJ Cruiser 4x4
    The Expert Answer that you are referring to is for a 2012 Toyota Tundra 4x4. The 2012 Tundra has different rear bumpstops than your 2007 FJ Cruiser 4x4. The part # TABSTORSEQ that fits your Cruiser will not fit on the Tundra. Timbren offers a few different options for you to add some suspension enhancement for your Cruiser and it all depends on how you plan on using it. The Rear Off-Road Bumpstops # TABSTORSEQ are rated for 6,000 lbs whereas the Timbren Rear Suspension Enhancement System...

    As your 2021 Toyota 4Runner is lifted, you will indeed need to use spacers when installing a Timbren suspension enhancement system.

  • Recommended Suspension Enhancement for a 2020 Toyota 4Runner TRD
    I recommend using the Timbren jounce-style suspension enhancement for your 2020 Toyota 4Runner because it is a quick installation and once you're done there is absolutely no maintenance. Since no air has to be added these kits simply work when they are needed and you don't have to think about them. For standard use you need part # TTOFTAC4A for the front and part # TTORSEQ for the rear, but if you plan on going off-road you need part # TABSTOF for the front and part # TABSTORSEQ for the rear.

  • Will Timbren Suspension Help Level a 2007 Toyota FJ Cruiser That Has More Weight on Passenger Side
    The Timbren suspension enhancement will replace the axle bump stops on your 2007 Toyota FJ Cruiser. They will work independently front and rear, and side to side. So, when you are carrying a heavier load on the passenger side of the vehicle it will compress the hollow rubber spring and become more rigid as the load is applied. This will help keep the vehicle from leaning heavily to that side. It will not affect the empty ride of your FJ Cruiser. The Timbren suspension has a weight capacity...

  • Timbren Suspension Enhancement for a 2011 Toyota FJ-Cruiser Trail Edition
    Adding suspension enhancement like Timbrens will help with sag and increase stability and ride quality. If your 2011 Toyota FJ Cruiser is a 4-wheel drive model, for the front you can use # TTOFTAC4A that you have referenced. There is no option for the front if it is a 2-wheel drive model. For the rear if it is 2- or 4-wheel drive use # TTORSEQ. I have included links to the instructions for both sets for you to view. I have also included a link to our FAQ article on Timbren suspension enhancemen...

    I do have some Firestone Coil-Rite Air Helper Springs # F4135 for your rear axle. If your springs have lost some compression and your rear end feels sloppy, these will help tighten up the back suspension to help especially if you have a trailer connected to your 1999 Toyota 4Runner. If you're bottoming out when hitting bumps/dips in the trails you will want to get the Timbren Active Off-Road Bumpstops # TABSTOR4R for the rear.

  • Improving Ride Quality on a 2015 Lexus GX 460 Towing a Trailer on Rough Roads
    Using Timbren helper springs on your 2015 Lexus GX 460 will improve the ride quality on those rough roads. It may not completely eliminate everything but it will be a vast improvement. What is likely happening is the weight of the trailer is pulling down on the vehicle and compressing the factory suspension so that there isn't as much space for it to travel up and down. Hit a bump and it will bottom out sooner. For front help springs I recommend # TTOFTAC4A and for the rear # TTORSEQ. Another...

  • How Do Timbren Springs Install on the Front Axle of a 2004 Lexus GX 470
    We have not yet had the chance to install Timbren front suspension enhancement springs # TTOFTAC4A so we do not have a video. We do have the instructions which I have linked for you below. Installation is fairly straight forward. There are 4 steps: 1) Raise vehicle allowing the axle to hang freely. 2) Where four bump stops exist, remove the rear bump stop. 3) Mount Timbren assembly using existing holes and Timbren supplied fasteners. 4) Lower vehicle.
