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.

  • Does Spacer Come with Timbren Suspension Kit for 2003 Ford F-250
    Yes, the spacer is included with the Timbren kit part # TRF250SDE and this is a confirmed fit for your 2003 Ford F-250. We have an 8k kit too with the part # TFRTT350E but there isn't a way to upgrade one from the other though. I would go with the lighter duty kit since the ride quality won't be as harsh.

  • Timbren Suspension Enhancement Fit For 1997 Ford F-250HD 4WD
    The difference is fit, as three of the parts you mentioned are for F-350 cab & chassis and not a fit for the 1997 Ford F-250HD 4WD. The parts that fit that truck are the following: - Front: Timbren Front Suspension Enhancement System # TFF2504A - Rear: Timbren Rear Suspension Enhancement System # TFR250SDE OR - Rear: Timbren Suspension Enhancement System - Severe Service - Rear Axle # TFRTT350E The difference between the two rear kits is their application; the # TFR250SDE is for occasional...

  • How To Prevent Vehicle Sag and Sway on a 2002 Ford F-250 with In-Bed Camper
    The Timbren Rear Suspension Enhancement System part # TFRTT350E is exactly what you will want to use on your 2002 Ford F-250 to haul your in-bed camper as they are designed for exactly this purpose and will take a lot of the sway out due to the higher center point as well as sag. There really is not a better system on the market for use with an in-bed camper. However, they will not increase the payload capacity of your vehicle nor will any aftermarket suspension enhancement system claim...

  • Timbren Rear Suspension Enhancement System Instructions for 1997 Ford F-250- F-350 Heavy Duty
    I am sorry to hear you are having trouble installing the Timbren Rear Suspension Enhancement System item # TFRTT350E on your 1997 F-250 or F-350 Ford Heavy Duty. That system is a confirmed fit for your truck. Unless there are after market suspension components in the way it should fit. I have linked a couple pictures from the installation instructions. It looks like there is an existing bump stop you will have to remove and the channel it goes through must come out as well for the Timbren...

  • Does Timbren Severe Service Rear Suspension Kit # TFRTT350E Fit 2000 Ford F-250 Short Bed
    Yes, the Timbren Severe Service Rear Suspension Kit part # TFRTT350E is a confirmed fit for your 2000 Ford F-250 Super Duty short bed. This does not require the bumper to be left installed to function or install properly.

  • Suspension Enhancement Recommendation for a 1999 Ford F-250 V10 Supercab 8 ft Bed
    The Firestone Air Spring kit part # F2550 will not fit the Supercab V10 models with an 8 foot bed due to interference from the frame design of the truck. Your best option would be a jounce style spring enhancement like the Timbren part # TFRTT350E which has been confirmed as a fit for your truck. The great thing about these kits is that they do not require any air line running or maintaining of air pressure. You install them and they are there when you need them and not when you don't.

  • Best Suspension Enhancement Recommendatio for 2004 Ford F-350 Dually with Camper Shell
    The best suspension enhancement kit for your 2004 Ford F-350 dually for your application is the RoadActive Suspension kit part # RAS3611-HD as it gives you the support you are wanting, is easy to install, and unlike other options (including two you mentioned) that hurt the ride quality this actually improves the ride quality and stability.

  • Helper Springs for a 2000 Ford F-250 Towing a 5th Wheel Trailer
    For your 2000 Ford F-250 towing a 5th wheel trailer I recommend the Timbren helper springs but the ones you will need are # TFR150SDE because the other ones you mentioned are for Severe Service vehicles only. Since you need support from towing a 5th wheel trailer the Timbrens are a better option than air bags. This is because the load weight and position will basically be exactly the same every time which is what Timbrens are good for. Air bags are better if you carry uneven load frequently...

  • Can Timbren Kit Install on 2001 Ford F-350 with Lift Kit
    Timbren kits like the part # TFR350SDE and the # TFRTT350E both can be used on vehicles with lift kits installed. Timbren makes spacers that can be added to the kits to take up the extra room created by the lifts. We have 1 inch spacers like the part # A25723-90AH00 and half inch part # TA25722-90P00. Basically you would need to go with a spacer combo that matches the amount of lift the kit you install provides.

  • Suspension Enhancement Recommendations for a Fleet of 2002 Ford F-350 Ambulances
    Air springs are a good solution if the load in the back is frequently changing side to side. When it remains static a better solution would be to go with a non-air system. The load in the back of an ambulance can change depending on the personnel inside, the equipment, and the patient. But there is also not as much room to move the variables around in the back. Either type of system would work for you. For your ambulances, and for an air system, I recommend the Firestone system, # F2550....

  • Best Timbren Suspension Enhancement For 2003 Ford F-250
    There is a big difference between the two Timbren kits that fit your 2003 Ford F-250, as the # TFR250SDE is for applications like towing a 5th wheel trailer or travel trailer, and the # TFRTT350E is for service trucks or work trucks. They are not the same with stiffer rubber, the difference is the # TFRTT350E is single-convoluted so it does not have almost any "give" to it. So the correct kit for your '03 F-250 is the following: - Timbren Rear Suspension Enhancement System # TFR250SDE This...

    The SumoSprings Rear Axle Jounce Spring kit # SSR-114-54, which fits the 2WD version of the 2002 Ford F-350, has a 2800-lb weight capacity which would be suitable for your travel trailer application but since you have lift on the truck I suggest the Timbren kit # TFR350SDE if you have 2WD or kit # TFRTT350E if you have 4WD. For these kits we have spacers available for lifted trucks that will ensure you can position these springs at the correct distance above the axle. When the truck is...

  • Would the Timbren System for a 1999 Ford F-350 Affect the Ride Height
    The Timbren Rear Suspension Enhancement System # TFRTT350E that you referenced will not affect your unloaded ride height at all on your 1999 Ford F350HD. These do not begin helping support your factory suspension until the suspension has been compressed somewhat, so basically your vehicle will feel and look unaffected when not loaded. I attached an FAQ article on Timbren systems for you to check out also.

  • How To Level The Rear Of A 2000 Ford F-250
    I have the perfect options for you. In order to level the rear of your 2000 Ford F-250, I recommend using a set of heavy duty jounce springs such as the Timbren Rear Suspension Enhancement System part # TFRTT350E or a set of rear air bags like the Firestone Ride-Rite Air Helper Springs part # F2550. The jounce springs will help to level the added weight over the rear axle by replacing the factory bump stops with a set of heavy duty rubber bump stops positioned over rear axle under the...
