An example of sag on the rear suspension under a heavy load.

The resistance from Timbren's Suspension Enhancement System works with the trailer's suspension to keep it level, which improves driving performance for your vehicle. When hauling heavy loads, you will often see the rear of the vehicle sag, while the front end raises up. In this case, the rear axle is handling not only the weight of the cargo, but more of the vehicle's weight as well. Since less weight is on the front axle, the front tires are making significantly less contact with the road, reducing traction, which decreases the vehicle's steering and stopping performance.


Under pressure, hollow rubber springs are designed to progressively support the suspension.

The Timbren system has a custom bracket that will be bolted onto the trailer frame above the axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits one inch 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 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 provides increased resistance, stiffening the suspension and keeping the trailer level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the trailer. 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 hauling off-center loads.


An example of a trailers swaying without Timbren SES

Timbren Suspension systems help compensate for all of the probable causes of trailer sway - from unbalanced loads to gusts of wind from passing vehicles. Installing Timbren will make your trailer track better behind your vehicle and provide a safer more comfortable towing experience.


An example hauling a heavy load with and without Timbren.

When hauling heavy loads, the resistance from Timbren's hollow rubber springs will work with the trailer's suspension to raise the trailer's ride height. This is will take additional strain off of the hitch components and help the trailer ride easier.

Ask the Experts about this Timbren Trailer Leaf Spring Suspension

  • Boat Trailer Wheels Contact Interior of Wheel Wells When Driven Over Speed Bump
    We will start off with the presumption that the trailer is new, its suspension is in good order and that it is properly rated for the boat's weight. In this case you should not experience the tires contacting the inside of the wheel wells when you drive over a speed bump, nor at any other time. This kind of issue can happen when the tire size on the trailer is changed to one of a larger overall diameter. Larger tires reduce the available clearance for the normal suspension travel of...

  • 5th Wheel Trailer Pulls to the Right After Making Right Hand Turns
    It is possible that the trailer is heavier on the one side causing the suspension components to wear unevenly. I recommend inspecting the suspension and look for signs of excessive wear such as egg-shaped holes, flat springs, broken parts, and anything out of the ordinary. When replacing suspension parts you should do both sides of the trailer at the same time so that they wear more evenly. Something that will help the suspension to last longer is to install some helper springs. We...
