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.

I wanted to reach out about the system not appearing how we have it pictured on site. What was different about the kit that you received?



by:
Ford

Solid quality product and certainly helped with my above .75ton extra load configuration need. I give it a thumbs up and easy install. My application is a "small" camper with a wet weight of about 2000 pounds on a Ford F250; this certainly helped with conering roll stablity and less work on the overload springs.



by:
2000 Ford F-250 and F-350 Super Duty

Had Timbren rear suspension system installed on my F250 Super Duty. I use with a 3horse heavier blt trailer with 8ft short wall. I can't believe how much more stable the truck feels with this system. Love it and would most certainly recommend this system be added to their truck. I wish I knew years ago to add this system to my truck.




by:
1999 Ford F-250 Super Duty

I ordered the Happy Jack camper system and the Timbren overload package for my 1999 Ford Super Duty. Both items showed up quickly and were very easy to install. Directions helped but they fit perfectly and were described on etrailers’ website perfectly. I will continue to shop etrailer. Thank you

As the other reviewers noted, these rubber springs were extremely easy to instal. The greatest difficulty was the removal of the existing rubber blocks.

These springs have added ample capacity to my truck and have relieved a lot of pressure from my leaf springs. I recommend them!



by:
2000 Ford F-250 and F-350 Super Duty

very easy to install, took about 30 minutes, didn't jack up the vehicle or take off tires, just dropped spare tire out of the way and went to work. Haven't towed my 5th wheel yet, but I am confident that this product will stop my truck from sagging so much under the load.



by:
2000 Ford F-250 Super Duty

Super easy install on a 2000 Ford F250 super duty. I haul a 24 foot enclosed snowmobile trailer in the mountains which sagged the rear bumber by two inches. These Timbrens split that in half so I gained better front end control. Very important while in the snow!
Very happy with them.

Bought these to help with 5th wheel load. Really works well.We are full timer RVers so they get a work out for a bit. Would recommend.



by:
2009 Ford F-250 Super Duty

Items received ahead of delivery date. Installed on 2000 F250 diesel and pulled our 2009 32 foot Sandpiper 5th wheel with awesome results. The rear of the truck didn't sag nearly as much under the 1,800 lb pin weight and the handling was vastly improved. Once the truck settled down the 1 1/2 inches of air gap between the bottom of the bumper and the axle, the truck didn't sag any more. Great product for the price, easy to install and performes as advertised.



by:
2000 Ford F-250 Super Duty

I haven't used the Timbren suspension enhancement for my F250 as of yet. The shipping was fast and they product came as advertised. It was easy to install and looks great. I think that it will work great when I hook up to my fifth wheel.



by:
Ford F-250 Super Duty

Prompt shipping, and the product appears to be just as described. These springs were easy to install, once I got the factory bumps off. I carry over a ton in my F250 daily, and these raised it back up a good inch with the load on.



by:

Work great to keep my truck from sagging when I pull my equipment trailer, smooth normal ride with empty truck, easy to install with no maintenance

by:

I know it will be lovely when loaded or the trailer on. However,it rides like a wagon empty with brand new premium shocks and struts empty. Thud thud thud. You really cannot feel the shocks or suspension. Found exact same item plentiful for 60 bucks on eBay after I bought these for 250. I may cut these in half or put air bag on. I do not like the ride empty. No hard feelings. It is a good product maybe just not for me.

  • Rear Suspension Enhancement System for a 2000 Ford F-250 4x4 Towing Gooseneck Trailer
    The best rear suspension enhancement product for your 2000 Ford F-250 is going to depend on a couple things. First, how your gooseneck hitch is attached to the frame of your truck and second, whether you prefer adjustable air springs or fixed rubber springs. For an air spring system, I recommend installing the Firestone Ride-Rite Air Helper Springs, # F2550, that you referenced. This system is compatible with most gooseneck and fifth wheel hitches and have been tested for up to 5,000 lbs...

  • Rear Helper Springs to Reduce Squat on the Back of a 1999 Ford F-250 Towing 12K Dump Trailer
    For your 1999 Ford F-250 4x2 the Timbren springs # TFR150SDE are a great option. The 6,000 pound rating is for the whole system and that is the vertical load limit. So even if the trailer was loaded to 12,000 pounds gross weight it still would not even come close to producing 6,000 pounds of vertical load so no worries! It will definitely help with the squat and improve ride quality while towing. I have included a link to a video showing an example installation for you.

  • Will Timbren Suspension Enhancement Fit on 1999 Ford F-250 with Lift
    A space of 5-5/8 is very little. Especially on a lifted truck. It sounds like you're not measuring the correct location or your suspension is pretty worn out. The Timbren # TFR150SDE system you're looking at is the correct kit for your 1999 Ford F-250 and must have at least 6-3/4 inches between the frame and the axle. If you're measuring from the bump stop the axle this would make sense. The bushing shouldn't be much from the frame.

    The Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88298 cannot be used with a gooseneck hitch. I contacted Air Lift to verify and they were able to confirm that they do not make a suspension system for your vehicle that is compatible with a gooseneck hitch.

  • Rear Suspension Enhancement Recommendation for a 2000 Ford F-250 Towing a Horse Trailer
    I prefer the Timbren springs to air bags when towing a trailer. I recently installed a set of the Timbren springs in my Dodge Ram and they do a great job when I am towing my fifth wheel trailer. The Timbren springs are more ideal when the load in your truck bed is constant, such as a trailer. The air bags are more ideal when the load in your truck bed fluctuates or when the load may be heavier on one side than the other. For your 2000 Ford F-250 4x4, I recommend installing the Timbren...

  • Suspension Enhancement Recommendation for a 1992 Ford F-250 with Fifth Wheel Rails
    I have a suspension enhancement solution I can provide for you, but there is no way to use air suspension enhancement like the part # F2071 on a 1992 Ford F-250 with fifth wheel rails as the two brackets interfere with each other like you have found. Your best option would be a Timbren setup like the part # TFR150SDE. This will fit your vehicle and would be compatible with your rail kit.

  • 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...

  • Timbren Rear Suspension Enhancement for a 1989 Ford F-250 GVW of 6600 lbs
    You can install either the 6,000 lb system, # TFR250SDE, or the 8,600 lb system, # TFR350SDE, on your truck, but they will not increase the weight carrying capacity of your truck. You will still be limited to the weight capacity that Ford has set for your truck. These springs were designed to work with your factory suspension to help reduce sag and improve safety and handling when hauling heavy loads. I would recommend installing the 6,000 lb springs because you are not gaining an advantage...

  • Recommended Rear Suspension Enhancement for 1999 Ford F-250 to Reduce Sag with 5th Wheel Trailer
    To greatly reduce the sag you're getting with the 5th wheel trailer hooked up to your 1999 Ford F-250 I recommend adding the Timbren Rear Suspension Enhancement System # TFR150SDE. This is because the heavy-duty aeon rubber springs used for the Timbren systems offer a bit more support than the urethane constructed springs on the SumoSprings. This will allow for a more level and smoother ride when the truck is under load. This along with the Timbren's overall higher capacity (6,000 pounds...

  • Compression Size of the Timbren Rear Suspension Enhancement System TFR150SDE
    At its full capacity the Timbren Rear Suspension Enhancement System item # TFR150SDE will compress to 50% of its normal size. I just spoke with my rep at Timbren. The spring portion of the SES is 3-3/4" tall and it compresses to just under 2" when a 6,000 lbs load is placed on it. It will not stick out past the sides of the 4 1/2" x 4 1/2" bracket when it is fully compressed.

    How you use your truck will decide whether you need a passive-type system or something adjustable. A passive system like the Timbren Aeon Springs, part # TFR150SDE won't have any effect on your truck's ride until a load is placed on your rear suspension (whether it's cargo in the bed or the pin weight from your 5th wheel). When your stock suspension is compressed, the Aeon spring will contact the axle, providing extra cushioning and stability and reducing body roll. If you don't often carry...

  • Weight Distribution or Suspension Enhancement for my 1995 Ford F-250
    It appears all of your weights are inline. If you load your trailer with about 700 lbs of tongue weight sway will not be an issue. There is not a great deal of profile for wind or a passing semi to get a hold of or a weight issue your dealing with as you can move the car forward or rearward to get the right tongue weight.

    When determining the weight rating of the weight distribution system needed, any load in the tow vehicle to the rear of the back axle needs to be figured in as tongue weight. We typically figure the tongue weight of a trailer as being 10 to 15 percent of the trailer weight. With your set up, you are in the 700-1000 lb tongue weight range. I would recommend the High Performance Trunnion System, part # RP66022. This system is designed for trailers with tongue weights ranging from 600-1200...

  • Better Ride on Rough Roads for a 1997 Ford F-250HD
    I am sure there are some tires that you could use but the tires that we carry would not work since they are designed for trailer use only. Another possible solution is to change the suspension or add suspension enhancement. Using Timbren springs, # TFR150SDE for 2-wheel drive or # TFR250SDE for 4-wheel drive, will lessen the travel in the stock suspension and take the bite out of bumps and pot holes. I have linked videos showing installations of each.

    The Timbren Rear Suspension Enhancement System part # TFR150SDE which is a fit for a 2000 Ford F-250 is designed to produce around 1/2" - 1-1/2" gap. It will still work to reduce sag/squat with a gap but not till the threshold of the suspension is reached. Some prefer more of a buffer than others since the ride can be rougher when engaged. Nevertheless, you can use the spacer part # A25723-90AH00 for 1" or part # TA25722-90P00 for 1/2" to close the gap.
