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.

worked perfect. Very easy install. Made the vehicle nice and stable when loaded.



by:

Work as advertised. Truck only drops 1" . Easier & less expensive than air bags



by:

Superb. Exactly what was needed.



by:

Third truck I’ve used Timbren’s on, they are great. No more broken leaf srings. Quick shipping. You won’t regret this purchase.



by:

I have a 2020 Ram 1500 Classic. They were easy to install once I used soap, not soapy water. I tried the soapy water and could not get them in. Used straight up Dawn and they went right in.



by:

My husband attached them to his truck and my husband stated that they were extremely easy to install, directions were very simply and easy to follow. Shipping was extremely fast and efficient and arrived right on time. We haven't attached our RV to our truck and haven't taken our camping trip yet. So we can't give a review about how well the truck will handle once a load is attached.

this product is great! I put everything on like the instructions said,the ride was a little stiff so I jacked the back of my 3/4 ton back up took the 1 in.rubber disk off.now the ride is perfict.thank you!!!!!!!



by:

The Timbren ses went on easy and worked like a charm. Thanks so much.



by:

easy installed !! have not take pickup out and test it with enclosed trailer.



by:

Works well. Pain to install but does the job. Don't attempt to install without air impact



by:

The Staff of etrailer were outstanding in helping with my orders. Packages came in a day early (that was great)



by:

Shipping was so efficient arrived days before estimated. Order was placed and within an hour was shipped!!!



by:

Great product, but I had to go buy my own hardware to mount ,the nuts that came with kit would not fit the bolts way too big.



by:

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:

Really makes a difference when hauling a heavy gooseneck.



by:

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



by:

They look as shown on the home page
Fast service



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:

nice ride with my 5th wheel



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:

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.

  • Which Weight Distribution Hitch for a 2007 Ford F-150 Towing a 7,000 Pound 31 Foot Travel Trailer
    With length of 31 feet I would highly suggest using a weight distribution system with a Dual-Cam sway control system. Calculating 10-15 percent of the trailer weight gives you an approximate tongue weight range of 700-1,050 pounds. The best fit then for a weight distribution with dual cam sway control would be Reese Trunnion Bar Strait-Line System, part # RP66084. This system is a great fit for your trailer weight and the Dual-Cam Sway control will really help to keep the 31 foot trailer...

  • Timbren Suspension Kit Recommendation for 2014 Ford F-250 Towing Fifth Wheel
    A Timbren setup would be a great way to reduce sag on your 2014 Ford F-250 when towing your fifth wheel. The part # TFR250SDG would be the kit to use and not the part number you referenced. Unlike air suspension kits this would not interfere with your fifth wheel rail brackets or require you to maintain air pressure in the bags. I attached an install video for more info as well.

  • Timbren Rear Suspension Enhancement System for 4WD 2006 Ford F150
    The Timbren Rear Suspension Enhancement System item # TFR1502D you referenced is for 2WD only 2006 Ford F-150s. For your 4WD F-150 I recommend the Timbren Rear Suspension Enhancement System item # TFR150D. This system has a 6,000 lbs weight capacity and will definitely help to address the sagging you are feeling when your truck is loaded down.

  • Can Timbren Rear Suspension Enhancements Be Used With Weight Distribution On 2008 Ford F-150
    The use of rear suspension enhancement along with a weight distribution kit is not recommended. They will tend to work against one another. If sag on your 2008 Ford F-150 is caused by a load or a fifth wheel or gooseneck trailer then suspension enhancement is the way to go If your F-150 is a 2-wheel drive I recommend part # TFR1502D. This system helps provide additional support to give you a smooth, comfortable ride and will not affect the ride when your truck is empty. It will become...

  • Choosing Firestone or Timbren Suspension System for Towing 3-Horse Trailer
    Given the choice between the Timbren system ( # TFRTT1502D for 2wd or # TFR150D for 4wd models) or the Firestone # F2350, I'd choose the Timbrens because although the springs won't have any effect on the vehicle ride when there isn't load being applied, they'll get progressively stiffer as more weight is added. The Timbrens have a 6K capacity, but you'll be limited by the payload capacity of your truck. The Firestone springs don't carry a weight capacity, per my contact at Firestone. If...

  • Suspension Enhancement for a 2005 Ford F-150 Super Cab Towing a 5th Wheel Trailer
    I recommend going with a Timbren system like you have referenced. These types of systems work well for loads that do not change much, like a 5th wheel trailer, but each side can also work independently of the other for varying loads. For a 4-Wheel drive model you can use # TFR150D that you have referenced which is rated for 6,000 pounds. For 2-wheel drive models use # TFR1502D, also rated for 6,000 pounds. The capacity is based on vertical weight in the truck bed so the 6K capacity will...

  • Solution for Trailer that Sags When Generator is In Truck Bed when Using Weight Distribution
    The Timbren kit part # TFR150D is going to give you additional suspension support to help out with the weight of your generator, but the ideal solution will be to add more spring bar tension to your weight distribution system. If you can try angling the spring bars further down or use fewer links on chain hangers to see if that helps.

  • Suspension Enhancement Recommendation for 2005 Ford F-150 for Use with Draw Tite Gooseneck
    I have a suspension enhancement solution I can provide for your 2005 Ford F-150 that has a Draw Tite gooseneck hitch installed, but the air bag kits will not work as they will interfere with the bracket kits of the hitch. Instead you would want a Timbren kit part # TFR150D. This will replace your jounce bumper and provide you with additional suspension support when needed.

  • Suspension Enhancement Recommendation for 2007 Ford F-150 Work Truck
    All of the suspension enhancement products that we carry are designed for use on vehicles with suspension in good working order. If your vehicle's suspension is already to the point where is sags consistently, I recommend having the vehicle's suspension inspected to ensure that it is still safe. If a qualified mechanic determines that the suspension needs replaced, I recommend adding suspension enhancement after the suspension has been replaced. This will help extend the life of the suspension...

  • Suspension Enhancement Recommendation for 2006 Ford F-150 with Fifth Wheel Rail Kit
    We have suspension enhancement solutions for your 2006 Ford F-150 that are compatible with the fifth wheel rail kit but the air bag kits are not going to work. The best solution is going to be the Timbren kit part # TFR150D which will give you the suspension support you want and would not interfere with the fifth wheel rail kit. It's also nice because it doesn't require you to run any air lines or maintain air pressure.

  • Rear Timbren Helper Springs for a 2005 Ford F-150 4x4
    Well, as they say at Timbren, you can never have enough S-E-S! For the rear of your 2005 Ford F-150 you would use one set of # TFR150D. I have linked a video showing installation of this kit for you. Set # TFR1504D will not fit the 2005 Ford F-150. It is designed for 2009 to 2015 Ford F-150 trucks with stock height excluding SVT Raptor models.

  • Suspension Enhancement Comparison for 2006 Lincoln Mark LT, Timbrens or Air Bags
    For your 2006 Lincoln Mark LT the Timbren kit part # TFR150D is a confirmed fit that will work well to provide additional suspension support. The advantage this kit has over air bags is that once you install it you basically don't have to worry or think about it again. Unlike air bags which require you to keep track of air pressure depending on how much suspension support is needed. The advantage to air bags though is that you do get to fine-tune the amount of support needed whereas Timbrens...

  • Suspension Enhancement Recommendation for 2006 Ford F-150 Towing Fifth Wheel
    For your 2006 Ford F-150 we have suspension enhancement that would fit and work well. But since you have a fifth wheel hitch rail kit installed in the bed of your truck you'll have to go with a Timbren setup like the part # TFR1502D for if you have a 2 wheel drive or part # TFR150D.

  • Heftier Weight Distribution or Timbren Suspension Enhancement for a 2008 Ford F-150
    Ideally you want a weight distribution (WD) system that your 1,010 lbs of tongue weight (TW) plus the weight of any cargo behind the rear axle of your tow vehicle falls in the middle of. If a WD system is rated too high then your ride will be stiff but if it isn't rated high enough, as is your case, you won't even know that it is there. Since your WD system isn't really doing anything for you right now I highly recommend using a WD system that is better rated for your setup. The Equal-i-zer...

  • Weight Distribution and Sway Control Recommendation for a 2007 Ford F-150 4x4
    If your 2007 Ford F-150 is rated for 7,200 pounds, I cannot recommend that you tow the 8,000 pound trailer and car. Adding weight distribution and/or suspension enhancement will not increase the towing capacity of the vehicle. However, if you check the owners manual for the towing capacity, it may state that the truck can be used with weight distribution. If that is the case, then it should provide another capacity when using weight distribution which may be higher. If it is higher and...

  • Timbren Rear Suspension Enhancement Recommendation for a 2006 Ford F-150
    For a standard 2006 Ford F-150 you want the 6,000 lb Timbren Set # TFR150D. The 7,000 lb Set # TFRTT150D is a Severe Service kit and is designed for vehicles that will have a pretty constant heavy load like if you use a slide-in camper or salt spreader frequently - or even if you used your truck with a crane or aerial device like what you see with a tow truck. Attached is an installation video of the 6K Timbren kit being installed on a 2004 F-150 for you to check out.

  • Will an Air Spring Kit Work With 2006 Lincoln Mark LT and Fifth Wheel Hitch?
    Unfortunately there is not an air bag kit that will work on your 2006 Lincoln Mark LT with an in-bed hitch; there is a jounce-style suspension enhancement system that is a fit, the Timbren # TFR150D for a 4WD model or # TFR1502D for a 2WD model. These springs do not affect the empty ride of your truck so they will not work the same as an air bag kit, but they are going to be beneficial when you tow your trailer, working to reduce body roll and absorb shock over rough roads. These springs...

  • Will Exceeding Truck's Towing or Payload Capacity Damage Suspension Components
    Failed suspension components like what you described on the F-150 you perform work on can certainly be from exceeding its payload or tongue weight capacity from an overloaded bed and trailer. It's hard to say for certain that this is the culprit as I'm not sure exactly how heavy a trailer he tows with the truck but the fact that it keeps happening (and way sooner than it should) after repairs indicates that something is indeed being overloaded.
