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.

  • Will the RoadActive Suspension Custom Leaf Spring Enhancement Kit Fit My 2024 Ford Ranger Raptor?
    Hello Devon, Yes, the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS29VR will fit your 2024 Ford Ranger Raptor. I see that there are air bag kits available for the 2024 Ford Ranger, but unfortunately none of them fit the Raptor model. We do have the Timbren Rear Suspension Enhancement System # TFRRGR. Timbrens are great if you’re carrying a constant load, but when you’re unloaded they can create a rougher ride, especially when you hit bumps in the road. Adding the #...

  • Are Timbren Jounce Springs a Good Option for Suspension Enhancement on 2020 Ford Ranger
    The Timbren Rear Suspension Enhancement System # TFRRGR that fits your 2020 Ford Ranger are a really good option for suspension enhancement on your truck, and are exactly what I would use if it was my Ranger. These will be something you can put on your Ranger to improves its traction and handling when you are towing (or have a load in the bed), but it won't affect how your truck drives on a day-to-day basis. The reason for that is there will be about a 1" gap after the installation so you'd...

These feature a simple bolt-on install without any drilling required. They will do a great job of helping provide rear end support while towing or hauling.

    To reduce the suspension sag of your 2020 Ford Ranger when you are carrying your slide in camper a really great option is the SumoSprings part # SS86MR which will give you the support without negatively affecting your ride quality like other options or requiring maintaining air pressure like the air bag kits.
