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.

by:

The hardware that came in the kit was completely wrong. Stated M10 x 60 and 90 mm. Came with three different lengths of M8 hardware of neither length. Had to source hardware locally. Much too expensive for having to spend more money for the right bolts. Just hope this inattention to detail is not an indication of the quality of the product. Will likely not purchase products from this company again.



by:

Love the design and simplicity of the product. Unfortunaly one of nuts that is welded to the inside of the bracket was just floating around in the box when I opened it up. It didnt look like anyone had tampered with it, maybe a quality control issue as it was a little rusty because of some poor welds. Im on a time crunch so I ended up making it work but definetly bummed I recieved a sub par $xxx product.

  • Timbren Suspension Kit for 2022 Ford F-250 with Heavy Duty Tow Package
    The Timbren kit # TFR250SDJ does not require a mounting plate above the axle as it is designed to contact the round the plate that is currently on the axle that is mounted below the spring pack. I would recommend sticking with this kit even though you have the heavy duty tow package. Going with a heavier duty kit would create a harsher ride quality.

  • Recommended Suspension Enhancement for 2022 Ford F-250 With Plow and Salt Spreader
    The Timbren Suspension Enhancement System # TFR250SDJ will work, but I recommend the # TFRTT350J instead. This is the severe service kit which is designed for applications like your salt spreader where the truck has a constant load. The difference is that the # TFRTT350J already has the springs compressed which will give you a better ride with the spreader. Normally I would recommend air bags like the # F95FV since you won't have a lot of weight in the truck outside of winter. These will...

  • Will the Timbren Suspension Enhancement System Fit a Lifted 2019 Ford F-250
    In regards to the Timbren Suspension Enhancement System part # TFR250SDJ which is a fit for a 2019 Ford F-250, these will fit lifted applications but you'll need to add spacers to make up the difference. The Timbren Spacer part # TA25722-90P00 for 1/2" or part # A25723-90AH00 for 1". Please note, you'll also need to make a trip to the hardware store for longer bolts. We don't carry the Timbren Ford F-250 Spacer Kit at this time but it comes with the same spacers as the above.

  • Is The Timbren Suspension Enhancement System # TFR250SDJ Supposed To Spin
    Hey Frankie, The bracket for the Timbren Suspension Enhancement System # TFR250SDJ has a locknut in it that makes it feel like the bolt (part #4) is fully tightened when it's not. Their techs have stated that you just have to push past this point and keep going to fully pull the spring up and lock it in place.

    It is possible you can use the Timbren Suspension Enhancement System # TFR350SDJ (which is made for a Ford F-350) on your 2020 Ford F-250, but we have never done this and it hasn't been tested so I just can't guarantee a good fit. There are spacers that will work with your F-250 and the Timbrens that are designed to fit it, the Timbren Suspension Enhancement System # TFR250SDJ.

  • Suspension Enhancement for 2020 Ford F-250 with Rear Lift Kit Solution
    That's really hard to say since none of our options have been tested with your lift kit. How big of a lift is it? A jounce spring setup might be a better option since you can use spacers with them to take up the additional space created by the lift like with the Timbren # TFR250SDJ with the spacer kit # A25723-90AH00 which is one inch thick. This is a confirmed fit for your 2020 Ford F-250.

  • What is Ideal Space Between Timbren and Axle for 2019 Ford F-250
    I would recommend sticking with the amount of space you have now with your Timbren # TFR250SDJ because if you use a spacer to take up any more space you'll end up with a harsher ride quality. What you can do is try it without the spacer and see if you like the balance between ride support and ride quality and then evaluate if you want to add a spacer or not. My guess will be you'll like without the spacer.
