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.

Video Transcript for Comprehensive Review: Timbren Suspension Enhancement System-TDRTT3500

Hello, everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this Timbren rear suspension enhancement system. Now, this is a custom fit part. It is designed to fit the 2000, the 2002 Dodge Ram 2500 trucks, the 1994 to 2002 Dodge Ram 3500 trucks, and the 1994 to 1999, Dodge Ram 3500 cabin chassis models. And on a custom fit part like this, always like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show if this'll work tree application.Now this will improve your suspension, your handling and the safety.

It provides additional support as needed. So you always have a nice, smooth, comfortable ride. It will allow the leaf spring ample movement while cushioning light loads, and it does not affect the empty ride of the vehicle. It will become more rigid as more weight is added. This will increase stability, provides great performance while hauling heavy loads, and helps reduce vehicle sag.These do work independently side to side, help compensate for any off-center loads.

They do reduce body roll when swerving and turning corners, and they will act as shock absorbers taking the brunt of any bumps and rough roads. Helps extend the life of your vehicle suspension. Does include everything laid out here on the table. It includes the two A-eon hollow rubber Springs right here. All the vehicle specific bracket you need to install it, all the hardware you need...

Nice set of detailed instructions that'll describe how to install it. Now it does install directly onto the frame. There's no drilling required. Few specs on this, the capacity is 7,000 pounds. Now the Timbren springs will not increase your vehicle's weight carrying capacity, so you do want to make sure not to exceed the manufacturer's recommended weight limit.

And these are designed to work with a suspension system that is in good working order. But that should do it for the review on the Timbren rear suspension enhancement system..
