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.

I appreciate the fast response to get us the item that was lost in transit. We will be doing with you in the future. Thank you.

I have a 2021 Silverado high country 3.0 duramax 2wd. It has the adaptive ride control. This product does reduce squat however , I couldn’t imagine towing any distance with them installed. Very rough ride. I need to find a better solution.



by:

They work great. Hauled my camper about 3hrs with a 325# tongue weight and the 4runner sat flat and drove great. I like these better than air bag and they install in less than 30mins. No more inflating and deflating then inflating and deflating for the trip home.

etrailer was very helpful in getting the products I needed quickly.

Excellent service yet again, as always thank you Etrailer

Put them on my 2018 gmc 2500 and it rides like there is no trailer behind us. Well worth the price

haven't had a chance to install yet too cold out.if possible send again in a couple of weeks and I will leave you a review thanks.



by:

Excellent product that was easy to install. These definitely helped to reduce the sag while towing. However, they did make things a bit more bouncy when going over bumps. I'll take that over the sag and swaying of my trailer any day.

  • SumoSpring VS Timbren for 2017 Ram 3500 for Ride Quality and 5th Wheel Towing Support
    Since you really want a good ride quality the SumoSpring Solo # SSR-312-54 is the way to go. This will give you the support you are wanting without making the ride quality harsh like the Timbrens do. Timbrens provide a lot of support but the ride quality (specifically unloaded) isn't great. The SumoSpring option is a much better balance between support and ride quality so it's what you'll be the most happy with.

  • Best 2024 Ram 3500 Timbren Suspension Kit for a Slide-In Camper
    Hey Jason, thanks for reaching out! The Timbren Rear Suspension Enhancement System # T94VR is the best Timbren kit for your 2024 Ram 3500 because the other Timbren kit, part # TDR3500CA, is designed for standard use while the T94VR is the severe service kit that works better for heavier applications like salt spreaders and slide-in campers. Are you planning on having the camper in most of the time, or is it a once every so often kind of thing?

  • Should 2014 Ram 3500 Timbren Kit Have 1" Gap Between the Spring and Axle
    Hey Scott, thanks for reaching out! The Timbren Rear Suspension Enhancement System # TDR3500CA will need a 1/2" to 1-1/2" gap for proper installation on your 2014 Ram 3500. The only Timbren kits that have no gap are ones that are installed on a motorhome. What I recommend doing is installing the Air Lift LoadLifter 5000 Air Helper Springs # AL57295 kit instead because you get to choose how much support you get at any given time. To give you complete control I also recommend installing...

  • Towing Capacity of 2015 Ram 3500 Diesel Single Rear Wheel
    I looked up the payload capacity of your 2015 Ram 3500 single rear wheel diesel and it looks to be 4,140 lbs. So if you plan to carry around 4,000 lbs in the bed you should be fine. You'd also be fine to tow a 2,000 lb trailer as well.

    Hi Robert, I checked with all of our manufacturers for you and there is not an air bag kit that is a fit for your 2005 Dodge Ram 3500 cab & chassis dually. There is one option that will work for your truck, which is the Timbren Rear Suspension Enhancement System # TDR3500CA. While Timbrens won't give you the more customizable load support of air bags, they'll still be an upgrade for your suspension.

    The correct Timbren Rear Suspension Enhancement System (SES) for your 2019 Ram 3500 pickup should be part # TDR3500CA because the other option, part # T94VR, is for Severe Service vehicles like tow trucks.

  • Comparing Timbren Rear Suspension Enhancement System for 2016 Ram 3500 Towing 5th Wheel
    I understand the confusion based on the difference in capacity. The key is the difference in design. The Timbren Rear Suspension Enhancement System # T94VR is designated as a Severe Service kit so the springs are always engaged. Although the capacity is slightly lower at 8,000 lbs, the design is intended for a constant heavy load like a salt spreader or in-bed camper. Based on the frequency of your towing you want the Timbren Rear Suspension Enhancement System # TDR3500CA. These have...

    The Timbren Rear Suspension Enhancement System # TDR3500CA referenced in your question is confirmed to fit your 2016 Ram 3500. When the springs are installed, there should be about a 1/2 inch to 1-1/2 inch gap between it and the contact point when the truck is empty. If you find that the spring is almost or is touching the axle, Timbren recommends that you simply remove the rubber spacer that was supplied. If you have already done this, I recommend taking the truck out for a test drive...

    The correct Timbren Rear Suspension Enhancement System for a 2016 Ram 3500 with truck bed camper is part # TDRTT3500D as these were actually designed for this exact purpose. The other option part # TDR3500CA is just designed for standard towing applications.

  • Comparing Timbren Rear Suspension Enhancement Systems for a 2019 Ram 3500
    The correct Timbren Rear Suspension Enhancement System for a 2019 Ram 3500 is part # TDR3500CA. The Timbren Rear Suspension Enhancement System part # T94VR is for trucks with a constant heavy load like if you had a truck bed camper or service bed instead of standard bed. These springs are engaged constantly and not something you would really want on a daily driver. The capacity is a bit confusing I'll admit but rest assure, part # TDR3500CA is what you want for general use and towing.

  • Timbren Rear Suspension Enhancement For a 2023 Ram 3500 Dually Long Bed
    The Timbren Rear Suspension Enhancement System # TDR3500CA is the standard rating Timbren springs for your 2023 Ram 3500 Dually with an 8' bed. Do note these will not fit if you have the factory air suspension option. We also have the Severe Service Kit # T94VR which are rated for trucks which always carry heavy loads. So if you are only using the truck with towing heavy loads or installing a service bed these are the best option.

  • Recommended Timbren Suspension Enhancement For 2008 Dodge Ram 3500 With Salt Spreader
    Based on the fact that you are concerned about the ride quality, and you keep the truck unloaded in the summer, I would recommend the # TDR3500CA over the severe duty # T94VR. The # TDR3500CA still has a high capacity at 8,600 lbs for your salt spreader but does not have the same Severe Service kit designation and design as the # T94VR. It is likely you will still see some difference compared to before the installation of the jounce-style springs, but it will not have the same impact as...

  • Recommended Timbren Suspension Enhancement for 2019 Ram 3500 Dually
    For your 2019 Ram 3500 Dually Diesel I recommend the Timbren Rear Suspension Enhancement System # TDR3500CA. This jounce spring system is rated for up to 8,600 lbs and will progressively support your load by getting more rigid as more weight is added. It will act as a shock absorber and then as a stabilizer as weight increases to reduce body roll and sag. It won't increase your Ram's weight capacities but it will provide better support.

These and all other suspension enhancement options for your rear axle are shown on the linked page.

But they will otherwise not alter the ride when the truck is unloaded. I suggest the...

    The Timbren item # TDR3500CA is the same as the DR3500CA and is confirmed to fit your 2021 Ram 3500. I would stay as far away from Timbren's as possible unless you're towing with a work truck. They will make for an extremely unpleasant and stiff ride when you are not towing your trailer. Your tongue weight won't be anywhere near their maximum capacity and you will feel them on every bump. Instead I recommend the SumoSprings Rebel Custom Helper Springs item # SSR-301-40-2. This system has...
