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 Feature Review Timbren Suspension Enhancement System-T65MR

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Timbren Severe Service Rear Suspension Enhancement System. Now, this is a custom fit part, it is designed to fit the 2022 Toyota Tundra trucks. And on a custom fit part, what I like to recommend for you is to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now, this kit here will improve the suspension, the handling, and safety on your vehicle, and this is a severe service kit, and they're recommended when using like a slide-in camper or a salt spreader on your vehicle. Any application that'll require maximum stability, meaning reducing roll and sway, calls for a severe service upgrade.

And most rubber springs used on pickup trucks are double convoluted design, provides a perfect blend of capacity and ride quality, but these rubber springs that are used on the severe service, as you can see, they are a single convoluted design. Basically, the single convoluted springs are shorter and wider, and they're designed to resist weight more aggressively, and the result is reduced ride quality in exchange for more stability. Now, these do work independently side to side, these will help compensate for off-center loads. They do reduce body roll and swerving in turning corners. What's also nice is these do act as shock absorbers, taking the brunt of any bumps and rough roads, which will help extend the life in your vehicle suspension.

This part will include everything shown here, it includes the two Aeon rubber springs, these vehicle specific mounting brackets, and the hardware for its simple installation. And these do install directly onto your frame, they replace the bump stop, there's no drilling required. Does come with a nice set of instructions that'll describe how it goes together. Few specs on this, the capacity is 7,000 pounds. Now, one thing I do wanna mention is even though you're increasing the spring rate by adding this upgrade, this does not increase your gross vehicle weight rating of the vehicle, so you still wanna make sure not to exceed the manufacturer's recommended weight limit.

And also, this is designed to work with a suspension system that is in good working order. But that should do it for the review on this Timbren Severe Service Rear Suspension Enhancement System..

  • What Is The Difference For The Timbren Jounce Springs For a 2022 Toyota Tundra?
    First we have the Timbren Active Off-Road Bumpstops # T83MR for your 2022 Toyota Tundra. These bump stops allow for the most suspension travel while still absorbing road shock to improve your suspension comfort off road.

  • Suspension Enhancement Kit for 2024 Toyota Tundra With Factory Lift
    Hey Mark, I recommend going with the kit you looked at, which is Timbren Suspension Enhancement System - Rear Axle # T45MR along with Spacer Kit # T68MR. If you had a camper on the bed, or had the rear end maxed out all the time, then I'd recommend the Severe Duty Kit # T65MR, but I doubt you need that. If you used it and didn't actually need that much support, then your truck would suffer from a rough ride all the time.

  • Recommended Rear Suspension Enhancement for a 2022 Toyota Tundra With Slide In Camper
    I recommend installing the Timbren Suspension Enhancement System # T65MR on your 2022 Toyota Tundra. These rubber jounce springs are designed to provide added support when used with slide in campers like you have or other heavy items like a salt sprayer. This will greatly reduce the amount of sag in your suspension and give you a level and stable ride with all the additional weight.
