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 when loaded. 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 when loaded or towing because the rubber has more travel.

These look like they will cure the evils of the heavy load God's. Easy to install and they look like they are quite stout. I will find out in a couple of weeks from now.



by:

Hitch fit great and the instructions were easy to follow.



by:

Install was easy. Raised our Thor Gemini up as product said it would. Great job etrailer!



by:

had this product before. left it on my old truck when I traded. Now I have to replace it, really like what it does for my towing a travel trailer. just have to find time to put it on. speedy delivery arrived undamaged, which is nice.



by:

They definitely reduced sway and lean when driving. But also seems like you really feel every bump and increase road noise?
I assume since vibration from axle can now travel directly to frame?
Might need to upgrade shocks?
Might soften liitle over time?
Might need to get softer onesv
Only have gone 80 miles with them so far.
Will give it another few hundred miles and see what feel then.

Overall pretty happy So far.

2017 Thor Gemini TX

Strainer/basket is holding up well after one year of use in our RV, no issues.

Customer service is exceptional and any questions were answered immediately

Good product, I’ve attached a couple photos. The last one is a before and after



by:

Works great on my Honda odessey !! Great customer service as always!



by:

Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.



by:

Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.



by:

The product first arrived in a damaged box with one of the washers missing, but ETrailer did resupply that. The hardest part was finding a shop able (needs the right tools to depress coil springs) and willing (a potential liability issue messing with suspension) to replace it for a reasonable cost. Eventually a local tire shop agreed to. This was for a 2014 Honda Odyssey, especially for pulling a pop-up. Took two camping trips last summer, one before and one after installation, and I have been pleased with the added stiffness in the rear suspension. It made about 1 to 1.5 inch of difference in resting position when fully loaded and towing and has helped smooth out bumps and humps in the road - both when towing and not.



by:

Great fitment

by:

Delivery was fast, instal was quick & easy. Later today I will see how they work when I hook up to the 5th wheel. By all indications right now I believe they exceed my expectations.



by:

I put this product on my Trooper. The install was easy is you take the back wheels off. I towed this weekend and I did not bottom out. If they hold up over time, this is a great product.



by:

I would recommend this product to anyone. I pull trailers with a 1/2 ton truck and will never have another one without this product on it.



by:

Price was good compared to other sites. Shipped very fast. Installation was very easy.



by:

Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too



by:

Offers firm suppirt for loads. A little bouncy with no load. Easy to install.

  • Suspenbsion Enhancement Option For 2018 Ford Flex Limited AWD
    Hello Kevin, thanks for reaching out. An air suspension kit like the Air Lift # AL60821 is a great option for the 2018 Ford Flex Limiterd AWD since it allows for adjustability. If you want to skip over that, the next best option is the Timbren Rear Suspension Enhancement System # TFRFLX. These will help to support the rear end by reducing sagging and improving stability. They have a 3,000 lb capacity so they will make a noticeable difference. The only downside of Timbrens is they can make...

  • Recommended Suspension Enhancement for a 2019 Ford Explorer 4WD
    Clyde, using Timbrens like the Timbren Rear Suspension Enhancement System # TFRFLX will definitely help reduce rear sag. These springs have 3,000 lbs of load leveling capacity, increases stability, and includes custom-fit brackets and hardware. If you still have sag after adding the Timbrens, then you need to adjust the head on your weight distribution system so that more weight is redistributed to the front.

  • Air Bags or Timbrens Recommendation for 2017 Ford Explorer
    For your 2017 Ford Explorer the choice of suspension enhancement comes down to a few things and what you value the most. The Timbren kit part # TFRFLX provides a super easy install, no maintenance, and great suspension support. The downside though is that unloaded ride quality will suffer since the spring is pretty harsh. If you will be in need of suspension enhancement basically all the time and like the no-maintenance aspect this is the winner. But if you need to have a decent ride quality...

  • How to Keep the Rear End of a 2017 Ford Explorer from Sagging When Towing a Trailer
    I didn't see any vehicle information but if you are still using a 2017 Ford Explorer you could add some suspension enhancement to the rear end. I recommend the Timbren Rear Suspension Enhancement System item # TFRFLX. These hollow rubber springs keep your rear end from squatting when you're towing a trailer. They have a 3,000 lbs load leveling capacity that progressively engages the springs the more weight you add to the rear of your SUV. I have linked an installation video below so you...

    Although the the Timbren # TFRFLX is confirmed to fit the 2014 Ford Explorer, it does not fit the Sport models.

The Air Lift 1000 will support your existing rear coil springs to help keep you level when towing or hauling a heavy load. They install inside of your rear coil spring suspension and have a durable polyurethane construction....

    The Timbren rear axle jounce spring kit # TFRFLX will not fit the 2018 Ford Explorer Sport but it is possible to use an AirLift air spring kit, part # AL60821, if you have need for additional rear axle support. This kit fits both 2WD and 4WD versions of your 2018 Ford Explorer Sport.

  • Recommended Suspension to Help Sagging on a 2012 Ford Flex
    I have a solution for you that will keep your rear end from sagging when you're towing with your Ford Flex but there are no air bag systems that will work with struts available. Instead you will want the Timbren Rear Suspension Enhancement System item # TFRFLX. These are confirmed to fit both the 2WD and 4WD models of the 2012 Ford Flex with coil springs or struts. The system provides additional support while becoming more rigid as weight is added to your vehicle. It works exceptionally...

  • Will Timbren Springs Eliminate Rear Sag on 2013 Ford Explorer when Towing a Trailer
    Timbren springs # TFRFLX will still allow the tongue weight of the trailer to pull down the back of your 2013 Ford Explorer a little, about an inch or so, so it won't take out the squat completely. The best solution for squat caused by towing a trailer is weight distribution (provided that your trailer hitch is rated for it). On boat trailers there is usually a straight tongue called a pole tongue. To use weight distribution you will need a pole tongue adapter # EQ95-01-5950. Then you...

  • Rear Helper Springs for a 2017 Ford Explorer 4x4

With this system once it is installed there is no maintenance you have to perform and the ride quality will be improved when loaded or unloaded. If you want to go with air bags and have rear coil springs I recommend the Air Lift system, # AL60821.

  • Comparing TImbren Jounce-Style and Coil SumoSprings for a 2012 Ford Flex
    I personally prefer the Timbren Kit # TFRFLX over the Coil SumoSprings # CSS-1069R for your 2012 Ford Flex basically because the Coil SumoSprings are kind of pressed into place and then secured with zip ties to help keep them where they need to be while the Timbrens are secured in place by a bolt. Both will do a great job at adding support to your suspension but in this comparison I'd go with the Timbren kit. Pro Tip - Make sure that your weight distribution (WD) system is rated properly...

  • Can Timbren Jounce Springs Be Used With a Weight Distribution Hitch On a 2014 Ford Explorer?
    The Timbren Rear Suspension Enhancement System # TFRFLX can be used with the weight distribution while you are towing with your 2014 Ford Explorer. I always recommend to start with the weight distribution as it helps to reduce sag and like your R3 will reduce trailer sway. Adding the Timbren springs will help improve stability and reduce body roll.

  • Will Timbren Rear Suspension Enhancement System Fit a Lifted 2017 Ford Explorer
    In order to install the Timbren Rear Suspension Enhancement System part # TFRFLX on a lifted 2017 Ford Explorer you'll indeed need spacers to fill the gap. The best option is to match the height of the spacer to the actual lift. We offer both 1" part # A25723-90AH00 and 1/2" part # TA25722-90P00. Please note, because of the spacer's you may need to source longer hardware to attach the spring to the bracket.
