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.

by:

As always amazing customer service and products to match.



by:

These things should have been installed from the factory. Body roll is basically non existent in a turn now, and going over large bumps, like poorly made roads, is so much more comfortable. Can't wait to tow with these.



by:

Just installed on 2008 Hyundai Entorouge seems to work well. Only problem was that I had buy new hardware because the supplied hardware was standard not metric.



by:

Easy installation and perfect fit!



by:

Fast delivery and easy installation



by:

Yes about one year ago i installed this product with excellent results so far.



by:

Very efficient and great to work with. Will definitely use your company again. Thanks



by:

Easy to install and working as expected.



by:

Just as overtired , they stiffened up the ride , plus no more sag in rear ended of truck .



by:

Order was delivered earlier than promised and was exactly what I was looking for to enhance towing with my 24 Ford F250



by:

Installed this on my 2001 Explorer. Install is easy (assemble unit, bolt on in place of existing bump stop). Annoyed to find it doesn't fit. Specs are gap 1/2"-1-1/2"; there was a gap of 2-3/4". Yeah, they sell spacers for $27 each, but it's really annoying to buy a $225 product that says it fits your truck, only to find that you have to spend 50% more to actually adapt it to your truck!



by:

Great service and quick shipping



by:

Easy to order on line received my order in less then a weeks, That's what I'm talking about didn't have to leave the house.



by:

I just installed them yesterday. Super easy, took maybe 25 minutes. Looking forward to towing my toyhauler soon.



by:

Easy installation. Good quality.



by:

First off the product was beat up with paint/power coating missing in several places on both. I was putting on a brand new truck with less than 800 miles on it so I elected to touch up before install. I’ve hear a lot about Timbren but never had them. I had airbags on my F350 but when I switched to a new Tundra I went with Timbrens. I’m a bit disappointed in the ride. Feels like I can feel a “bump” in the truck from the rubber pick hitting the axle when I go on a bumpy road. Thinking I should have went with airbags. As far as having a load on the truck and helping with the squat, they do as they are advertised.



by:

Awesome investment. Benefits of airbags without the price or the hassle.



by:

Was very easy to install and the instructions were easy to understand.
Thank you



by:

Great Product, arrived quickly and packaged well.

Will be buying from them in the future.



by:

Received in a timely manner and packed nicely. Instructions clear and went on easily.



by:

Installed in about 15 minutes,very easy.I pick up my new truck camper next week so I do not know how it works yet,but looks like it will work like its suppose too



by:

I bought a set for my F250 and like them so much that I bought a set for my F350. It prevents the vehicle from sagging in the rear when hauling towing heavy objects. Makes for a smoother and more stable riding experience.



by:

awesome sevrice EVERY time ive worked with these guys, really REALLY fast too... good guys



by:

Very easy installation!



by:

Installed a set on my truck and liked it so much I ordered this set for my Dad's truck.

  • Do Timbren Jounce Springs Work With Shocks Already Installed On 2018 Ram 2500 4X4?
    Good morning Michael, yes they are only made to supplement existing factory suspension on your 2018 Ram 2500 4x4. The Timbren Rear Suspension Enhancement System # TDR2500D get added in place of your existing bump stops on your truck's real axle, adding some reinforcement and support so that your suspension doesn't sag and get worn out as quickly. Are you towing full time, or is this just going to be towing the camper for some parts of the year, then go unloaded for the rest of the year?...

  • Recommended Suspension Upgrade for a 2022 Ram 2500 w/ Factory Air Ride
    Hey Joseph. Since your 2022 Ram 2500 has the factory air suspension, I recommend adding the Timbren Rear Suspension Enhancement System item # TDR2500D. These progressive rate springs install where your bump stops are currently mounted. The more weight you put on them the more they will engage and support your truck's suspension. What kind of 5th wheel trailer do you have?

  • What Options Do I Have To Reduce Road Shock On My Ram 2500 When Towing?
    Hey Lonny, The Timbren Suspension Enhancement # TDR2500D for your vehicle is going to be great at better absorbing the shock when towing so it is less noticeable. I am not too familiar with the Bilstein Shocks but I imagine that paired with the Timbrens is going to do nothing but help. Airbags are going to help more with and tilt or roll you feel so I agree going with the Timbren is the way to go. That kit I mentioned is a custom fit kit so no drilling is required. Has your Ram been...

  • 2016 Ram Power Wagon Towing Capacity and Rear Helper Spring Recommendations
    According to Ram the 2016 Power Wagon has a towing capacity of 9,800 pounds. The trailer you choose cannot weigh more than this when loaded and ready to tow. If it is a Laramie Power Wagon it is rated for a max of 12,450 pounds. And if it is a Tradesman Power Wagon it is rated for 12,650 pounds. For your 2016 Ram Power Wagon I recommend adding Timbren springs # TDR2500D which will fit 2- or 4-wheel drive models with or without overload springs. These springs will prevent the rear of the...

  • Will Timbren Rear Suspension Enhancement System Add Ride Height When Towing ?
    Hello Shawn, thanks for reaching out. The Timbren Rear Suspension Enhancement System # TDR2500D will fit the 2025 Ram 2500. Since you have a 4" lift you will need a few 1" spacers # A25723-90AH00 to compensate. These will not necessarily add any ride height when towing your 5th wheel, but they will prevent the truck from sagging as much, so it may ride slightly higher than it did before. Keep in mind if spacers are used, you will need to source longer bolts locally.

  • Is Timbren Or SumoSprings The Better Option For Occasional Towing?
    Hi Paul! Since you said occasional towing, I am going to steer you away from the Timbren option. They can be pretty rough and you will definitely feel it when you are not towing. If you had a constant load, it would have been an option, but I don't think you will be happy with them. The SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-312-54 will be the much better choice. Yes, it does have a lower capacity than the Timbrens, but I believe they are much better suited to your needs....

  • Will The Timbren SES # TDR2500D Fit On A 2021 Ram 2500 Power Wagon
    Hey Brit, Yes, the Timbren Rear Suspension Enhancement System # TDR2500D would be a fit for your 2021 Ram 2500 Power Wagon. These jounce springs have a 8,600lb load leveling capacity so I do want to warn you that the ride will be pretty stiff when you are loaded down. Something a bit lower capacity-wise like the SumoSprings Solo Custom Helper Springs # SSR-312-54 would still get the job done but wouldn't affect your unloaded ride quality as much.

  • Which Timbren Kit Fits 2018 Ram 2500 and is Best Option
    Hey David, I basically never recommend the severe service Timbren kits like the part # TDRTT3500E that fits your 2018 Ram 2500 unless the vehicle will basically be always towing at or near it's capacity since they are very harsh. So instead I would go with the part # TDR2500D for your truck.

  • How to Decrease Vehicle Sag and Improve Ride Quality on a 2014 Ram 2500
    I have the perfect option that will give your 2014 Ram 2500 both comfort and support but the Timbren Rear Suspension Enhancement System part # TDR2500D are prone to creating a stiff ride. I cannot guarantee whether or not you will experience this discomfort but if the springs are loaded then the chances of a stiff ride are high. For the best of both worlds (support/comfort), I recommend using a set of airbags like the Firestone Ride-Rite Air Helper Springs part # F2598. This airbag kit...

  • Will Timbren Kit for 2022 Ram 2500 Power Wagon
    Hey Timothy, the Timbren rear suspension kit part # TDR2500D that fits your 2022 Ram 2500 will get rid of the sag when towing if you replaced your bump stops with these. Since that's a pretty large amount of suspension drop I would make sure you aren't attempting to tow beyond the towing capacities of your truck.

  • How do I Know How Much Weight my Gooseneck Horse Trailer Can Handle?
    Hey Terry, thanks for reaching out! Your trailer GVWR is the max weight that your trailer can be when it's fully loaded. Since the trailer weighs in at 7,560 lbs at empty and you're loading up 2,950 lbs of horses, it means you'll be overloading your trailer. I'd be interested to know what the year/make/model is of your gooseneck horse trailer. I find it odd that the GVWR only allows 1,430 lbs to be added to the trailer, especially since horses aren't necessarily light creatures. What...

  • Will The Timbren Severe Service Kit TDRTT3500E Make Ride Rough When Unloaded
    Hey John, thanks for getting in touch. The brackets that come with the Timbren Suspension Enhancement Kit # TDRTT3500E are custom fitted for the 2020 Ram 2500, and there is no shorter bracket we can offer for this kit. The # TDRTT3500E kit is a severe service kit. It is intended for vehicles that have a constant heavy load in the bed like a slide in camper or salt spreader. They will do great when under a load, but they are going to be very rough when unloaded. They are really not designed...

  • Can Timbren SES and SuperCoils Be Installed Together on 2021 Ram 2500
    Hey Paul; you can install the # TDR2500D and # SSC-52 at the same time on your 2021 Ram 2500. The SuperCoils replace your OEM coil springs and the Timbren SES replaces the factory bump stop so they're in two different locations and won't interfere with each other.

  • Recommended Suspension Enhancement for 2019 Ram 2500 Towing 5th Wheel
    For your 2019 Ram 2500 I recommend the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-312-54 over the Timbren # TDR2500D. The reason is the difference in the impact on your unloaded ride quality. The SumoSprings have a weight capacity of 2,800 lbs which is more than enough based on your pin weight. Compare these to the Timbren with a capacity of 8,600 lbs. The Timbren is going to be a lot stiffer and I don't think you'll be happy with them installed when you aren't towing. The...

  • How to Reduce Sway on a 2016 Ram 2500 with a Lance 820 Truck Camper
    With how the Firestone Air Helper Springs, like the # F2706, will attach to the frame, you would not be able to install a Timbren # TDR2500D as well. Both of these options will mount in the same place, unfortunately. That being said, the # TDR2500D may be better for your situation than the air bags. I do typically suggest air bags as they are fully adjustable, but they can be a little lacking when under constant heavy load and are not as good at handling sway problems. Another upgrade...

  • Comparing SumoSprings to Timbren for 2021 Ram 2500
    The SumoSprings like the Rebel Custom Helper Springs - 2 Piece - Rear Axle # SS27GR and the Timbren # TDR2500D are almost the same height. The Timbren is 6-3/4" tall and the SumoSprings are approximately 7" tall with the brackets. Since these install in the same space there won't be much difference between the two when it comes to the fit. Based on that information, I would still choose the SumoSprings # SS27GR over the Timbren. The Timbren will be far more rigid with its design and 8,600...

  • Will Timbren Rear Suspension Enhancement TDR2500D Fit A 2018 Ram 2500 W/ 50 Gallon Aux Fuel Tank
    Yes the Timbren Rear Suspension Enhancement # TDR2500D you were looking at for your 2018 Ram 2500 will fit perfectly. They will be slightly compressed with your Titan 50 Gallon Fuel Tank full, but that is to be expected as that is quite a bit of weight. This is going to be a great option for you as the 8600lb rating of these helper springs will help keep your truck from sagging when you have the extra fuel tank full, and especially when you are hooked up to your 5th wheel trailer.

  • Rear Suspension Enhancement Springs For A 2022 RAM 2500 With Factory Air Suspension
    Yes, The Timbren Rear Suspension Enhancement System # TDR2500D will fit your 2022 RAM 2500 with factory air suspension. The Roadmaster Sway Bar # RM-1129-135 will not. The Timbrens will give you up to an additional 8,600 pounds of suspension support. These springs act like shock absorbers, taking the brunt of bumps and rough roads. Using these springs will not exceed the vehicle's weight-carrying capacity. I attached an installation video link below.

  • Are Spacers Needed For Timbren Suspension Enhancement on 2022 Ram 2500 Power Wagon
    If you're saying the space where the Timbren would install is 7" you wouldn't need a spacer. About an inch gap is what is recommended, and the Timbren # TDR2500D for your truck measures 5-3/4" in overall height. A 1" spacer is included which would make it 6-3/4". We do have the spacers though, the # TA25722-90P00 is the 1/2" and the # A25723-90AH00 is the 1". I would go ahead and measure to be sure. If it is 7" you could leave the spacer off or if you want them to engage sooner add a...

    The difference between the Timbren # TDR2500D and the # TDRTT3500E is that the TDRTT3500E are designed for commercial service trucks which will have a more beefy suspension system already and a slightly different frame. The TDR2500D is designed for the passenger vehicles like your 2017 Ram 2500, so this would be the Timbren SES you're looking for. Whether or not you have the off-road package on your 2017 Ram 2500 won't have any effect on which Timbren system you're using, so there's nothing...
