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.

  • Recommended Suspension Enhancement For A 2020 Ford F-150 Towing Occasional Loads
    Hey Dave, The Timbren Rear Suspension Enhancement System # TFR1504E you referenced is a fit for your F-150, but it has a 6,000lb capacity so it'll give you an terrible ride unloaded ride quality. These would be great if you're heavy hauling all the time but for occasional use you'll definitely want to go with something lower capacity like the SumoSprings Solo Custom Helper Springs # SS28UV. These have a 1,500lb capacity to help with your varying loads and have a much softer progression...

  • Suspension Enhancement for 2018 Ford F-150 Towing Trailer
    Hey Keith, 3-4 inches of sag when your trailer is hooked up is quite a bit. That makes me think your weight distribution system is not properly rated for the tongue weight of your trailer, your trailer is much heavier than what your truck is rated for, or your lift kit was not designed to be towing with it installed. Now with that said for that much sag a Timbren kit like the part # TFR1504E with the correct spacers to compensate for your lift kit would be your best option. How much of...

    Hey there Steve; thanks for writing in and when it comes to body roll and sway for your 2018 Ford F-150, the better option is the RoadActive Suspension Custom Leaf Spring Enhancement Kit, with the right one depending on if your F-150 is 2WD or 4WD: - 2WD: RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-B - 4WD: RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-Y Honestly, I would go with these over the Timbrens # TFR1504E, and frankly not even both...

  • Fifth Wheel Hitch, Rail Kit and Suspension Enhancement for 2018 Ford F-150 5.5 Foot Bed
    For your 2018 Ford F-150 5-1/2 foot bed we have suspension enhancement that is a fit and works well with an in-bed fifth wheel hitch, but none of the air bag kits will work. Instead you'd want to go with the Timbren kit part # TFR1504E which fits your vehicle and can be used with an in-bed hitch rail kit. I attached an install video for this kit for you to check out as well. Then for a fifth wheel rail kit the best option is the Reese custom fit kit part # RP50087-58 which is a no-drill...

  • Towing 5th Wheel Trailer with 2018 Ford F-150 with 5-1/2 Foot Bed
    I was able to pull up the online towing specs for your 2018 Ford F-150 and it looks like there is still a somewhat large potential range even within the specs that you provided depending on your axle ratio, drivetrain, and wheelbase. At the low end on your F-150 SuperCrew with the 3.5 V6 engine it shows a 5th wheel towing capacity of 6,500 pounds for the 4X4 model with a 145 inch wheelbase and the 3.55 axle ratio. At the high end your F-150 can have a 5th wheel towing capacity of up to...

  • Recommended Rear Axle Suspension Kit for 2018 Ford F-150 4WD Short Bed
    The best choice of rear axle suspension kit for your 2018 F-150 will depend on the type of towing or hauling you're doing. All rear-axle kits for your 4WD F-150 appear on the linked page. If you are routinely hauling cargo loads of widely varying weight then an adjustable air bag setup will give you the ability to match the bag air pressure to suit each different load. If you are towing a 5th wheel then you can get good results from a lower-cost jounce spring kit from Timbren that will...

  • Recommended Timbren System for a 2022 Ford F150 Tremor
    To add a set a Timbrens to your 2022 Ford F-150 Tremor you will need the Timbren Rear Suspension Enhancement System item # TFR1504E. This system has a 6,000 lbs capacity and will help support your stock suspension system when towing. Since your Tremor has a lift from the factory you will need the Spacer Kit item # T68MR to get the desired 1/2" to 1-1/2" gap between the jounce spring and the axle pad. I have linked an installation video below. You may also want to look into using a weight...

  • Will The RoadActive Suspension(RAS) Work With Timbren Jounce Springs on a 2018 Ford F-150?
    I do recommend removing your Timbren Rear Suspension Enhancement System # TFR1504E before you install either the 2,000LB # RAS3611-Y or 3,000LB # RAS3611-YHD RoadActive Suspension. The RAS mounts outside your u-bolts which is where the Timbren spring comes down to contact the axle. While there may be a small gap currently your rear end can float a bit side to side which may cause the jounce springs to contact the mounting arms which could damage both units. I personally feel the RAS is...

  • Available Anti-Sway Stabilizer Bar for a 2015 Ford F-150
    For an anti-sway bar that is a confirmed fit for your 2015 Ford F-150 I recommend taking a look at the Roadmaster Rear Anti-Sway Bar # RM-1139-177. The bar attaches to your rear axle and chassis, enhancing stability by diminishing the roll that can be caused by winds or shifting cargo. You may also want to consider the Timbren Rear Suspension Enhancement System # TFR1504E if your stability issues are happening when you are hauling cargo. These springs simply sit above your rear axle, minimizing...

  • Comparing Rubber Spring and Air Bag Suspension for 2018 Ford F-150 For Towing Support
    We have suspension enhancement kits that are a confirmed fit and will work great on your 2018 Ford F-150. Like you mentioned there are air bag kits like the Firestone part # F2582 which have the advantage of giving you total adjustability on how much suspension support you want. The downside is that you have to maintain air pressure in the air bags and have a bit more involved of an install. The other option is the rubber spring kits like the Timbren part # TFR1504E which have the advantage...

  • Comparing Timbrens and Air Bags for a 2020 Ford F-150
    The Timbren Rear Suspension Enhancement System part # TFR1504E is a good option for a 2020 Ford F-150 but the suspension has to reach a threshold before they engage and they do compress when this is done so you will still sag a bit while they are installed. If total sag reduction is your goal it's rather hard to go with air bags which will replace the Timbrens. The air bags allows you to adjust the pressure so not only will they engage right away but they also give a smoother ride. I recommend...

  • Suspension Enhancement Recommendation- 2020 Ford F150 Towing Small 5th Wheel
    A jounce spring replacement like the Timbren # TFR1504E would be a great choice. The Timbren Aeon spring will not change the ride of your truck unless the rear suspension is compressed (like when a fifth wheel is hitched up). As more weight is added, the springs get progressively firmer. Because the springs replace the factory jounce bumpers, the Timbrens won't interfere with the bracketry for your firth wheel hitch. The springs will also make your truck feel more stable in turns and can...

  • Can Timbren Springs, SuperSprings & Blue Ox Weight Distribution All Work Together 2018 Ford F-150?
    You are able to install the Timbren Rear Suspension Enhancement System # TFR1504E along with the SuperSprings # SSA28 while also using a Blue Ox TrackPro Weight Distribution # BLU55FR on your 2018 Ford F-150. The weight distribution is going to help the most with leveling your F-150 when connected to a trailer. The SuperSprings being a more active suspension than the Timbren will begin to engage sooner when weight is applied and will provide a more stable ride. The Timbren's with these...

The Timbren Rear Suspension Enhancement System # TFR1504E has a weight capacity of 6,000lbs. while the Timbren Suspension Enhancement System # TFRTT1504E has a weight capacity of 7,000lbs.

    I understand the temptation to want to go with the higher rated Timbren kit part # TFRTT1504E over the # TFR1504E for your 2018 Ford F-150 but in reality going with a higher weight rating will basically just make your ride quality much harsher whereas the lower rated kit will do a better job of balancing suspension support and ride quality.

    For your 2017 Ford F-150 with Curt fifth-wheel base rails installed, I recommend the Air Lift LoadLIfter 5000 Air Helper Springs # AL57284. This system will mount to the bottom of the truck's frame, so it can be installed along with your existing fifth-wheel brackets without any interference between the two. This will provide your Ford F-150 with up to 5,000 pounds of load-leveling support, reducing strain on the rear suspension while also improving safety and ride quality. The air springs...

  • Difference Between Timbren Suspension Enhancement for 2023 Ford F-150
    The # TFR1504E and # TFRTT1504E have different designs for different applications. More than likely you need the # TFR1504E for your 2023 Ford F-150. This kit will provide additional support and stability while towing and hauling. The # TFRTT1504E is a severe service kit designed to handle something like a slide-in camper or salt spreader that is always in your truck. This means it will be stiffer by comparison and result in a rough ride unless you have a heavy load in there at all times.

  • What Rear Jounce Springs do You Recommend for My 2022 Ford F-150?
    For great rear jounce springs for your 2022 Ford F-150, I recommend the Timbren Rear Suspension Enhancement System # TFR1504E. Apart from the 6,000 pound load capacity, the Timbrens becomes more rigid as more weight is added and results in greater stability (with or without loads) and a decrease in sag. They also compensate for off-center loads while hauling. The springs come with all hardware required for an easy installation. These Timbrens will fit both 2-wheel drive and 4-wheel drive models.

    Yes, you'll need to readjust the weight distribution system after installing the Timbren Rear Suspension Enhancement System part # TFR1504E on a 2021 Ford F-150. The reason for this is because the rear end sag will be reduced with the springs so adjustments to the system will need to be made to account for this.
