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 Rear Kit Recommendation for a 2022 Ford F-150 Raptor
    Thanks for reaching out! The difference between the Timbren kits are the weight ratings and ultimately how you'll be using them for your 2022 Ford F-150 Raptor: Standard Timbren Kit - # T75MR - 3,000 lb rating Off-Road Timbren Kit - # T73MR - 7,000 lb rating If you plan on using your Raptor for off-road situations (which is really what the Raptor was designed for) then you'll want the Off-Road kit rated at 7K since it's more rugged. If you won't be going off-road very often then you'll...

  • Recommended Suspension Enhancement for a 2022 Ford F-150 Raptor
    To level out the rear end of your 2022 Raptor when you are towing a trailer, I recommend the Timbren Suspension Enhancement System item # T75MR. These progressive load springs have a 3,000 lbs load leveling capacity. The progressive load control will get stiffer as the weight on them increases. This will keep your rear end from squatting down when you are towing.

  • Suspension Enhancement Fit For 2024 Ford F-150 Raptor
    Hi Jed, I checked directly with SuperSprings, the manufacturer of SumoSprings, and verified there is no fit for SumoSprings for your 2024 Ford F-150 Raptor. I did find another option that fit your truck, which are Timbrens, with the right part being the following: - Timbren Suspension Enhancement System # T75MR The # T75MR will work in the same manner as the SumoSprings, engaging with a load in the bed or when towing to help level out your ride and support the back end of your truck.
