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.

  • Timbren Suspension Enhancement Fit For 2022 Ram 1500
    The correct Timbren suspension enhancement fit for your 2022 Ram 1500 will actually depend on the cab style of your truck. The Crew Cab and Quad Cab are different fits than the Regular Cab, so you'll want to choose the right one based on that: - Crew Cab & Quad Cab: Timbren Rear Suspension Enhancement System # TDR1500DQ - Regular Cab: Timbren Rear Suspension Enhancement System # TDR1500DS Timbrens were a really nice choice for your Ram because of how much they will help its handling...

  • Best Suspension Enhancement for a 2016 Ram 1500
    There is certainly some give and take when adding suspension enhancements to a vehicle. The give being that you will sacrifice some of the ride quality while towing/loaded and the take being that you gain some of the suspensions strength back while towing/loaded. If you think about it, the suspension enhancements will stiffen the stock suspension to eliminate sag with a heavy trailer so it will be difficult to maintain the factory ride quality after they are installed. The best option...

  • How to Address a Sagging Rear End in a 2017 Ram 1500 Pulling a Travel Trailer
    Congrats on the new truck! I saw you were looking at suspension enhancement but I want to point you towards using a weight distribution system to address the sagging. It will level out your truck and trailer by transferring some of the weight from your Ram's rear axle to the front. Your 2021 Forest River Vibe 26RK has a tongue weight right around 1,000 lbs when fully loaded. With this in mind, I recommend the Equal-i-zer Weight Distribution System w/ 4-Point Sway Control item # EQ37120ET....

  • Suspension Enhancement Options For 2018 Ram 1500 With In-Bed Gooseneck Hitch
    Hello Al. You are correct that the Air Lift LoadLifter 5000 # AL88365 will not work with a B&W Turnoverball gooseneck hitch. The brackets go in the exact same place and there is no way to safely modify either of the brackets to make it work. The next best option for air suspension will be the Firestone Coil-to-Air-Spring Conversion Kit # F2595. These replace the factory coil springs with an air helper spring. This gives you the adjustability of an air bag, so you can level your ride while...

  • Recommended Timbren Suspension System for a 2025 Ram 1500 Crew Cab
    Hey Craig, that is correct. So since you have the Crew Cab, you're going to want the Timbren Rear Suspension Enhancement System # TDR1500DQ instead. I double checked with Timbren as well to make sure. If there is anything else you had questions with, please feel free to drop a comment and let me know!

  • What are the Heaviest Duty Non-Air Spring Helper Springs for a 2026 Ram 1500?
    Hey Joseph, congrats on the new truck. The heaviest capacity non-air bag springs we have available for your 2026 Ram 1500 are the SumoSprings Solo Custom Helper Springs item # SSR-307-40 you were looking at. These have a 1,000 lbs capacity and are compatible with the factory air suspension if your truck has it. We also have the Timbren Rear Suspension Enhancement System item # TDR1500DS if you do not have the factory air springs or item # TDRTT1500 if you do. I only recommend using these...

  • Is There Suspension Enhancement that Fits 2022 Ram 1500 TRX
    Hey Steve, I checked and your 2022 Ram 1500 TRX came with factory air suspension which the Timbren kit part # TDR1500DS does not fit with. We don't have any great options for versions of the truck that have air suspension. We know the SumoSprings kit part # SSR-307-47 will technically fit but it will interfere with the air suspension functionality.

  • Will Timbren SES Work With 2022 Dodge Ram 1500 Buckhorn Towing Forest River TT With Blue Ox WDH
    Hi Robert; as long as you don't have the regular cab the Timbren Rear Suspension Enhancement System # TDR1500DQ will round out your setup nicely. If you DO have the regular cab you need the # TDR1500DS instead. Both will provide additional support and help smooth out the ride while towing your travel trailer.

  • Recommended Solution to Fix Sag While Towing with a 2020 Ram 1500 Big Horn
    In this case, I recommend using the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-307-47 because they'll do a bit better job of keeping the factory ride nice and comfortable; these springs provide 1500-lbs of load leveling capacity, so your trailer's tongue weight and the weight of any payload should be considered. If your trailer's tongue weight/pin weight and the payload you carry is greater than 1500-lbs then the Timbren Rear Suspension Enhancement System # TDR1500DS would...

  • Timbrens Or SumoSprings For A 2022 Ram 1500 To Help With Sag While Towing Travel Trailer
    When choosing between The Timbren Rear Suspension # TDR1500DS and The SumoSprings Solo Custom Helper Springs # SSR-307-47 for your 2022 Ram 1500. I would recommend The Sumo Springs # SSR-307-47 over the Timbrens. Neither will completely eliminate sag and not will completely eliminate sag but the SumoSprings will offer the same quality as the Timbrens in terms of suspension support, but will not give you as harsh as a ride that the Timbrens would. The SumoSprings initial engagement is lighter...

    The # TDR1500DS Timbren Rear Suspension Enhancement System will help reduce or get rid of the sag you are experiencing with your 2017 Ram 1500. These will also help improve overall handling and give you a more comfortable ride by absorbing road shock and improving roll stability.

  • Do Adjustments Need to be Made With Weight Distribution on 2019 Ram 1500 w/ Timbrens
    Hi Jeremy; that's a good question and you'll actually need to go ahead and re-do the set up of your weight distribution system after adding the Timbren Rear Suspension Enhancement System # TDR1500DS to your 2019 Ram 1500. So it wouldn't just be making adjustments because your truck will be more level with the Timbrens. It will be worth it though since adding Timbrens will help ensure you are level to improve your Ram's handling.

  • Recommended Timbren Rear Springs for 2018 Ram 1500
    For your 2018 Ram 1500 the Timbren Rear Suspension Enhancement System # TDR1500DS will work perfectly. These hollow rubber springs feature a 6,000 pound capacity that will do a great job of providing additional support to the rear suspension and leveling everything out when you're under load. I really do like the Timbren systems because they offer superior support but you don't have to worry about adjusting anything before each trip like you would with air springs.

    Both the Timbren Rear Suspension Enhancement System # TDR1500DS and # TDR1500DQ that you referenced are designed to fit the 2011 Ram 1500, but there are a couple differences that may factor into which set will work for your specific model Ram and application. The Timbren # TDR1500DQ is not a fit for regular cab models of your Ram 1500, while the # TDR1500DS will fit this model perfectly. If you have the regular cab, you will want to go with # TDR1500DS. If not, then another deciding factor...

  • Does Suspension Sag Need to Be Factored in When Determining Ball Mount Rise/Drop
    Since the goal when picking out the correct rise/drop ball mount is to tow the trailer as level as possible you would want to compensate for sag like you mentioned. 3 inches of sag is quite a bit but you'd need to factor it in when towing if that's what you are experiencing. To combat the sag a great option is the Timbern kit part # TDR1500DS which will fit your 2017 Ram 1500 as long as you don't have factory air suspension.

    I have a suspension enhancement solution for your 2019 Ram 1500 but you can't use the Air Lift kits like the part # AL60828HD with lift kits. So instead you'd need to use the Timbren Kit part # TDR1500DS with lift spacers like # A25723-90AH00 for each inch of lift on each side of the axle to take up the extra space created by the lift.

  • Do You Recommend Timbrens or SumoSprings to Eliminate Sag on My 2022 Ram 1500?
    When considering whether to get Timbrens like # TDR1500DS or the SumoSprings like the # SSR-307-47 on your 2022 Ram 1500, I recommend the SumoSprings to deal with your rear sag. The SumoSprings will help restore the sagging as well as give you a smoother ride than the Timbrens. As far as compatibility, the SumoSprings will fit on both 2-wheel and 4-wheel drive models. They also do not require any maintenance after they are installed. If you need help with the installation of the SumoSprings...

If your Ram is a Regular Cab, you will need # TDR1500DS. If you have the Crew or Quad cab, then you'll need # TDR1500DQ.
