Reduced rear axle sag with Timbren suspension enhancement

Whether you're hauling heavy loads in your bed or cargo area or 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 your rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the leaf 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.


Action 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.


Trailer swaying as it is towed behind a truck

Because your 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.

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. 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 because the rubber has more travel.

Video Transcript for Review of Timbren Vehicle Suspension - Rear Axle Suspension Enhancement - T28MR

Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at the Timbren rear suspension enhancement system. Now, this is a custom fit part. It is designed to fit the 2019 and newer Chevrolet Silverado and GMC Sierra 1500 trucks. And on a custom fit part like this, I do 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 will work for your application.

Now, this kit here will improve your suspension, handling, and even the safety of your vehicle. These do provide additional support as needed, so you'll always have a nice, smooth, comfortable ride. Basically, it'll allow the least spring ample movement while cushioning any light loads, so it doesn't affect the empty ride of your vehicle. And this will become more rigid as more weight is added. There's increased stability, which provides great performance while hauling any heavy loads and it'll even help reduce vehicle sag.

Now, these do work independently, side to side, help compensate for any off-center loads. And they'll even reduce body roll when you're swerving or turning corners. They will also act as shock absorbers, taking the brunt of any bumps or rough roads, which will help extend the life of your vehicle's suspension. This kit will include everything laid out here on the table. It includes these two Aeon hollow rubber springs, the metal spacers, the rubber spacers, all the hardware you need for installation, and even a nice set of instructions that will describe how this all goes together.

These do install directly onto the frame. Basically, they'll replace the axle bump stops on the frame and there is no drilling required. Few specs on this, again, the capacity on these are 8,600 pounds. Now, one note I wanna mention, these Timbren springs will not increase your vehicle's weight carrying capacity, so you do wanna make sure not to exceed the manufacturer's recommended weight limit. And this kit is 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..

Well, I have just got them installed, but have yet to pull the trailer. Installation was easy. Price seems very high for what I got, but if it works, I'll be happy.
