Features to know about

Keep the Rear End Level and Stable: 3,000-lb Rear Suspension Support

Heavy trailers or bed loads can make the back of your vehicle sag and throw off your steering and braking. The Timbren Rear Suspension Enhancement System adds up to 3,000 lbs of load support using hollow rubber springs that sit above the rear axle. They stiffen progressively as more weight is added, keeping the ride level and your handling steady when hauling or towing. With the rear end supported, you maintain traction, control, and proper headlight aim even when the load gets heavy.

Smooth Out Rough Roads and Bumps: Hollow Rubber Spring Design

Bumps, dips, and rough terrain can make an unloaded ride uncomfortable. Timbren’s hollow rubber springs act as shock absorbers, soaking up road shock to give you a smoother, more controlled experience. The progressive design cushions light loads while allowing the factory suspension to operate normally under everyday conditions. You keep a comfortable ride around town but gain serious damping when it counts.

Reduce Body Roll and Off-Center Sag: Independent Spring Action

When corners get tight or loads shift to one side, each Timbren spring works independently to stabilize your vehicle. This helps control body roll during sharp turns or swerving maneuvers and keeps you level when carrying uneven loads. You stay steadier through curves and crosswinds, with less rocking and sway from trailers or heavy cargo.

Install It Once and Forget It: No Air Lines or Adjustments

Timbren’s system bolts directly onto existing frame points using custom-fit brackets—no drilling required. There are no air hoses, compressors, or gauges to set up or maintain. Once installed, it automatically engages under load and stays out of the way when not needed. It’s a straightforward setup that delivers reliable suspension support every time you hitch up or haul something heavy.

by:

Absolutely Pleased with the TIMBRENS. They were easy to install, and took less than an hour to install both. I noticed a slight stiffness in the ride as the rear bounced over a bad roadway. Towing is great, with a nice level and smooth ride. I am glad that I did not order the heavier duty Timbrens, than what was recomended for my truck. I believe the ride would have been too stiff. If you look at the photos showing the timbrens, the truck is still lifted in the rear, so what you see is a big gap between the rubber, and the steal plate. When the truck is lowered, there's 1" of space as it should be. BTW, I have been purchasing from etrailer for years now, and I have to say that I have never had any issues with any orders. They are my go to folks for all of my vehicle suppension stuff and trailer stuff. You can't go wrong with buying from them.

My F53 was like driving a waterbed down the road. With the Timbrens, it’s a different vehicle. Should have installed them years ago. Etrailer is my go to for anything trailer. FAST shipping and prompt responses to questions or concerns.

2022 F250 Super Duty. Super easy to install. I have about 3/4" gap between the spring and the plate. Time will tell how they impact the ride quality and how much sag they mitigate with my 5th wheel hooked up.

Timbren Spring Helpers were exactly what I needed on my Tundra plus a spacer kit since I have a 3” TRD lift. They were packaged neatly, with proper hardware, and excellent instructions! They absolutely do exactly what they are supposed to do! Truck rides much better and helps level out the load!

Great upgrade when pulling our 6500lb travel trailer. Helps with sag and control on the road on our Ram 1500. Change the stock shocks and if you choose, upgrade your stock springs, and you'll get the most out of your half ton.

I'm suitably impressed with the difference i feel.
I have about 250 lbs. of static load with my topper and Decked cargo system. This put my install gap with no spacers just under the reccomended 1 inch minimum.Then add a couple hundred more pounds hauling music gear 100 shows a year, and the stop is resting on the axle.
I feel the absorption of the Timbren material is better than the flimsy stock bump stops. More cushion.
Where i really feel the difference is in the stabilty of excessive side sway when turning while loaded.
I have a gig coming up that will involve some unpaved mountain roads to get there so I think i will have a real goid idea of how these Timbren's will perform.
Instalation took me about an hour at 11 p.m.
The product it of the highest quality in design and build.
And Etrailer is a company that I would not hesitate to buy from in the future.
Thanks Dee Dee.
You rawk!!

@Steve Thanks, we're glad you're happy with your # TFRFLX Timbren helper springs!

These were very easy to install, about 15 mins each. I have not been able to test them with a loaded trailer but they look like they will certainly help with back end sag.

Working great, it’s a nice and tough product

Supports my power wheelchair and rack with no problems. Handling is the same with or without a rear load. Very easy to install, [online] video was great



by:

Does a great job when towing a travel trailer. Really helps with windy conditions keeping the vehicle from dipping in rear with sway of trailer. Vehicle is much more stabile after the install.



by:

I got them to keep my Ford Explorer from squating in the rear when loaded, it did not seem to help so I switched to air bags, should have done them first.

Yeah, Timbrens are built for constant use. Like, landscaping work vehicles, tow vehicles, towing trailers daily, truck campers, etc. If they are not in consistent use, then they will make your drive very stiff. If you are only needing to prevent sagging every so often and not daily, then air bags are a much better choice.



by:

Had to have it professionly installed.bolts were torqued to the max and access to the bolts was impossible to get clear line for wrenches, when completed ride is better and vehicle sits higher. service and delivery was great

  • 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...

  • Solution for Suspension Enhancement That Fits 2014 Ford Explorer Sport
    Although the the Timbren # TFRFLX is confirmed to fit the 2014 Ford Explorer, it does not fit the Sport models. For suspension enhancement that will fit your 2014 Ford Explorer Sport I recommend the Air Lift 1000 Air Helper Springs for Coil Springs - Rear # AL60821. 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....

  • Rear Axle Suspension Enhancement for 2018 Ford Explorer Sport
    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. AirLift kit # AL60821 provides up to 1000-lbs of load leveling and it will help reduce strain on your OEM suspension and reduce sway.

  • 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...

  • Rear Helper Springs for a 2017 Ford Explorer 4x4
    For your 2017 Ford Explorer 4x4 I recommend the Timbren helper springs # TFRFLX. 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...

  • 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...

  • 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.

  • Timbren Rear Suspension Enhancement System for a 2017 Ford Explorer Sport
    Yes, the Timbren Rear Suspension Enhancement System item # TFRFLX you referenced fits all models of the 2017 Ford Explorer including your Sport model. I have linked an installation video.

    The Timbren Rear Suspension Enhancement System # TFRFLX that you referenced will install to the inside of the coil spring on your 2012 Ford Flex. The installation instructions for the springs are attached. Timbren states in the instructions that a professional installation is required for these jounce springs.

  • 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.
