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.

Easy to install. You may need an impact wrench to break loose the u-bolts that have to be loosened.

I actually found that airbags worked better for my truck and trailer. I ordered those from you as well. May I return the Timbrens for at least partial store credit?

by:

Easy installation. Good quality.



by:

Easy to install. Works as advertised. Etrailer rocks!



by:

Installed this on my 2001 Explorer. Install is easy (assemble unit, bolt on in place of existing bump stop). Annoyed to find it doesn't fit. Specs are gap 1/2"-1-1/2"; there was a gap of 2-3/4". Yeah, they sell spacers for $27 each, but it's really annoying to buy a $225 product that says it fits your truck, only to find that you have to spend 50% more to actually adapt it to your truck!



by:

Very easy to install. I got the product in two days. Love etrailer products. THANKS.



by:

Very easy to install took about 30 minutes. If it manages the weight of my trailer I will be more impressed with your product.



by:

Install was a breeze, can't wait to tow our camper with these babies on the Tundra

Very poor packaging. The box is coming apart and USPS reinforced it. Found out this product doesn,t work on a 2018 Winnebago Intent. It will cost me almost $[XX] to return it.
