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.

A little hard-hitting not as cushiony when you go over any bumps.



by:

I normally don't have this problem with you folks but when I looked at the box it looked like it was open and then wrapped up with packing tape, pretty beat up. I am missing all the nuts and bolts that go with this and only received one of the spacers. Is there any way someone can send me my missing nuts and bolts? I am not terribly upset about the missing spacer as luckilly I picked up both the 1 and 1/2 inch spacers separately and those did include the bolts to screw into the bracket.

Well, we said third time is the charm but not this time. I received the box on Saturday and yes, the same thing. The box was torn open on the front side seem and parts are missing,,, again. All I can say is "MORE TAPE, MORE TAPE,, MORE TAAAPE!!! I spoke to Phillip H. this morning and he is sending me just the missing parts. Hopefully it will get here in time for the next trip on July 1st. Fingers crossed!



by:

Easy installation.

Easy to install. Can’t wait to see how much it improves towing my trailer.

  • Best Suspension Enhancement For 2021 Toyota 4Runner Sagging While Towing
    Hey Bryan, Thanks for the photo and specific info you gave, and if you're sagging to the point that it's affecting oncoming drivers you definitely need suspension enhancement. That much sag is actually going to affect your 4Runner as well because the back end will experience more wear, and your tires are going to go quicker. You mentioned Timbrens and while those will work, there's a better option, which are SumoSprings: - SumoSprings Solo Custom Helper Springs # SS68DR The # SS68DR...

  • Will Firestone Air Springs Fit 2019 Toyota 4Runner With Lift
    Hi Ed, So long as the coil springs on your 2019 Toyota 4Runner remain the stock size, the Firestone Coil-Rite Air Helper Springs # F4135 will fit. They'll still give you excellent support for your 4Runner's rear suspension as you're towing or even just have a heavy load in the back.

  • Will Timbren or SumoSprings Fit Better on a 2019 Lexus GX 460 with a 2" Lift in the Back
    Hey Bob, Since your 2019 Lexus GX 460 is lifted in the back some, the Air Lift 1000 Air Helper Springs # AL94VJ aren't able to reach properly which is why you're not getting the effect you're wanting. You can add multiple of the 1" Spacer # TA25723-90AD00 to the Timbren Rear Suspension Enhancement System # TTORSEQ so it sits where it needs to instead of there being a big gap. The SumoSprings don't have a spacer kit so you'll want the Timbren kit for your instance.

Between these two, the better option for your 4Runner is going to be the SumoSprings: - SumoSprings Solo Custom Helper Springs # SS78DR The reason for that is they have a 1,800 lb capacity - which is going to be more than enough to help reduce the squat for a more controlled towing...

  • Weight Distribution Recommendation for 2016 LXE Aliner
    If you think your tongue weight will be at least 250 lbs the Fastway e2 Weight Distribution # FA92-00-0600 will work great. It sounds like you are really close if not over the figure. It's hard to come up with a WD system for a lower rated setup though. Most applications with that low of a tongue weight either have hitches not rated for WD systems or the WD system just isn't needed. To install a ball you'll need a thin walled socket like # ALL643216. For a 2 inch ball you would want part...

    The P3 Brake Controller part # 90195 is an excellent choice for a brake controller so you are off to a great start. To convert the 4-way to a 7-way so that you can install a brake controller all you would need is the part # ETBC7. This comes with everything needed so you would not need the other components you referenced. I attached an install video plus installation instructions for you to check out as well.

  • Is There Rear Suspension Enhancement that Can fit 2020 Toyota 4Runner with 3" Lift
    Hey Anthony, for your 2020 Toyota 4Runner I have a solution but there isn't a way to install air bags or SumoSprings so instead you'd need to go with the Timbren kit part # TTORSEQ and then 6 of the 1 inch spacers part # TA25723-90AD00 to take up the space created by the 3 inch lift on both sides of the vehicle.

    Timbrens would be horrible when you are off-roading. It would feel like you were constantly bottoming out your suspension. Your kidneys would hate you. I could not more strongly recommend SumoSprings for your 2023 Toyota 4Runner. The best option is going to be the SumoSprings Solo Custom Helper Springs item # SS68DR.

  • Heavy Duty Suspension Enhancement Recommendation for a 2022 Toyota 4Runner 4X4
    The heaviest-duty suspension enhancement we have for your 2022 Toyota 4Runner 4x4 is the Timbren Kit # TTORSEQ. Timbren jounce-style springs like this are known for being able to help out with heavier loads, however they are also know to make the unloaded ride a little more rough so for your application I recommend using the SumoSprings # SS78DR as they aren't as unforgiving as the Timbrens.

    When it comes to products to install on your 2022 Toyota 4Runner that are low maintenance, look no further than the Timbren Kit # TTORSEQ.

  • Timbrens or SumoSprings For Towing Light Trailer With 2018 Toyota 4Runner
    For your 2018 Toyota 4Runner, between the 6,000 lb Timbren Rear Suspension Enhancement System # TTORSEQ and 1,800 lb SumoSprings Solo Custom Helper Springs # SS78DR, since your trailer is only 4,000 lbs you will not have a heavy tongue weight so I recommend the lighter capacity SumoSprings Solo Custom Helper Springs # SS78DR. The 1,800 lb rating for these is more than enough for a light 4,000 lb camper trailer, as the Timbrens would be overkill and can give a very stiff ride. The SumoSprings...

  • Suspension Enhancement Product for 2021 Toyota 4Runner Towing Travel Trailer
    Given the 400 lb tongue weight you'll be dealing with, the Timbren # TTORSEQ which has a 6000 lb capacity would be your best choice. That being said, I'd recommend the # SS78DR SumoSpring instead. The SumoSprings # SS78DR have an 1800 lb capacity which would be plenty for the 400 lb tongue weight of your travel trailer, and are constructed of a more pliable material which would provide you plenty of support and a better ride quality when the system is under load.

  • Solution for Reducing Rear Sag on Off-Road Toyota 4Runner with Trailer Connected
    The only suspension enhancement product available that is confirmed to fit the rear axle of your 2017 Toyota 4Runner is the Timbren Rear Suspension Enhancement System # TTORSEQ. These jounce-style springs will do a nice job of reducing rear sag on your vehicle, however they likely aren't the best solution for your particular application.

If the lift utilizes the stock coil springs then there should not be an issue.

  • How Close to Vehicle Frame Should Timbren Springs Sit Once Installd
    Timbren likes to recommend 1 inch between the axle and the Timbren when the truck is unloaded. We have found that this works the best. For a 1/2 inch spacer you would need the part # TA25722-90P00 and then for a 1 inch spacer part # A25723-90AH00. One of each of these will work great to get your Timbren setup right where it needs to be.

    I spoke with my contact at Timbren and he said they don't have an official torque spec for the hardware on the Timbren Rear Suspension Enhancement System # TTORSEQ you referenced but tightening all the hardware to around 20 foot-pounds will be sufficient.

  • 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.
