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.

They work very well giving just the right amount of support with a load and not affecting the ride without a load.

  • Fit and Compatibility of Timbren Rear Suspension Enhancement on a 2015 Ram 5500 Cab and Chassis
    I confirmed with Timbren that the # TDR5500 is indeed the correct suspension enhancement spring for your 2015 Ram 5500 Cab and Chassis. The contents of the kit are designed for the stop over the axle as seen in the attached diagram. This kit includes 2 aeon rubber springs. The # TDR5500 can be installed whether you vehicle was equipped with or without factory top overload springs. What it sounds like you are describing is the upper overload springs. The Torklift # TLA7200 is a good...

  • Suspension Enhancement for Front and Rear of 2020 Dynamax Isata 5 Super C Motorhome
    For your 2020 Dynamax Isata 5 I recommend using the Timbren Front Suspension Enhancement System # TDF5500. This system will better serve your suspension as the majority of your added weight is over the rear axle. The # TDF5500HD is more designed for your severe service vehicles like tow trucks and vehicles that will have large plows mounted on them. For the rear I recommend the Timbren Rear Suspension Enhancement System # TDR5500. This will offer you more stability at 12,000lbs versus...

  • How Does Timbren Suspension Enhancement Weight Capacity Affect Vehicle Weight Capacity
    The weight capacity for the suspension enhancement kits we offer can be confusing in how it's listed but basically the kits provide their capacity in additional suspension support. So it adds that much support to the vehicle's capacity already listed. For example the part # TDR5500 would add an additional 12,000 lbs of suspension support to the vehicle. Now to make things even further confusing (hopefully not) this does not actually give the vehicle more weight carrying capacity. It just...

  • Recommended Suspension Enhancement For 2016 Ram 5500
    The Vin number doesn't help me find your current capacities, but I have the information needed to help with a solution. We have suspension enhancement systems that work with your current suspension to help with support and reduce sag. Your current payload is between 10,000 lbs and 12,300 lbs. So your current leaf springs are between 5,000 and 6,000 lbs minimum. I recommend the Timbren Rear Suspension Enhancement System # TDR5500 for the rear of your 2016 Ram 5500. This is a confirmed...

  • Recommended Suspension Enhancement For a 2011 Ram 5000 With Close to 13,500LBS On Rear Axle
    Honestly with these very heavy weights the Timbren # TDR5500 becomes the best option for your 2011 Ram 5500. This particular kit is rated for 12,000lbs of support capacity to the rear suspension. They are also less likely to become damaged under very heavy loads and you will not have to worry about the air pressure like you get with the Air Bags # AL88255.

  • Suspension Enhancement for 4-WD 2021 Dynamax Isata 5 Motorhome 28SS Built on Ram 5500 Chassis
    I suggest the Timbren Rear Suspension Enhancement System, # TDR550. These hollow rubber springs sit above the rear axle to help stabilize and level your Dynamax Isata 5 Motorhome. Because they work independently, the side-to-side movement helps to compensate for off-center loads. For the front suspension, I suggest the Timbren Front Suspension Enhancement System, # TUMDF70. These front hollow rubber springs help to stabilize and level your Dynamax Isata 5 Motorhome and provide a more...
