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.

You do not want to exceed the trailers weight carrying capacity. Also, this system is for trailers with a suspension system that is in good working order.

  • How to Improve a Rough and Bumpy Ride on a 2,000 Pound Fruefoff Trailer
  • I do have some suggestions. First off, make sure that the tongue weight is not too heavy or light. Typically tongue weight should be 10 to 15 percent of the gross trailer weight. A tongue weight that is too heavy would cause the rear end of the trailer to be more bouncy. Getting the trailer loaded properly will be the first thing you can do. As far as aftermarket suspension enhancement using a system like # TTRA1702 would help but it is only rated for 1,000 pounds for the set. All the...

  • Keeping Cargo from Moving and Shifting in Enclosed Trailer
  • Adding trailer suspension enhancement such as # TTRA1702 can definitely help with ride quality but I think the best solution to keep loads on the pallet is some cargo control devices. You could start with a cargo net, I have included a link to the various sizes we carry. A cargo net is a simple solution to secure a large group of items with one device. You can also get some E-Track, # E19148, and attach them to the sides of the trailer. Then use some D-Ring tie downs, # E59143, and...

  • Will Suspension Enhancement Help Prevent Trailer Sway on a 1969 Ideal Travel Trailer
  • In order to determine the best suspension enhancement solution for your trailer, you will need to know the trailer capacity and select a system based on that. If the trailer capacity is 4,000 pounds, then 2 sets of the Timbren Trailer Suspension Enhancement System, # TTRA1702, would be sufficient. I have included a link to the installation details for you. Your first line of defense against trailer sway is proper loading of the trailer. The tongue weight should be 10 to 15 percent of...

  • How Much Does a 1977 22 Foot Ideal of Idaho Travel Trailer Weigh
  • The best way to determine the weight of your 1977 Ideal of Idaho travel trailer is to take it to a truck scale, weigh station, or place where they sell bulk gravel and ask to weigh the trailer. I have included a link that should help. From what I could find (I could only go as far back as 1980) but in that year on a 22 footer the weight was about 4,000 pounds. If the weights and capacities are not on a plate on the trailer frame somewhere then to know for sure you are going to need a scale.

  • What Trailer Suspension Enhancement is Best for Preventing Axle From Contacting Trailer Frame

  • Recommendation of Timbren Trailer Suspension Enhancement System for a 3,000-Lb Utility Trailer
  • I would recommend to use the Timbren Trailer Suspension Enhancement System , part # TTRA1032, on your 3,000-lb utility trailer. This enhancement system is for medium-duty trailers. It has a weight capacity of 7,000 lbs. This does not mean that you will be able to carry more weight than what your trailer is rated for, but it will help reduce sag and sway when you put the load of your equipment on the trailer. It is always better to have more weight capacity than not enough weight capacity....

  • Suspension Enhancement Recommendation for a Fifth Wheel Trailer
  • For suspension enhancement for a trailer we have a similar setup to an air kit, but it's actually a rubber spring instead. For a 1,000 lb axle kit you would want the part # TTRA1702. For a 7,000 lb axle kit you would want the part # TTRA1032. For a 10k axle kit you would need the # TTRA15252. Timbren's Suspension Enhancement System has hollow rubber springs that absorb the brunt of the force on the trailer's frame, helping to reduce sag and sway ensuring better handling and tracking...

  • Timbren Trailer Suspension Installation for Trailer with Narrow U-Bolt Plate
  • The Timbren Trailer Suspension Enhancement System # TTRA1702 doesn't have to fit between the u-bolts of the trailer axle. All that is required is that the plate attaches to the frame and the rubber spring touches the axles so you could mount is so that the rubber spring contacts the axle to the inside or the outside of the u-bolts on the axle if needed.

  • Weight Distribution Recommendation for a 2011 Nissan Frontier Towing a 3000 lb R-Pod Trailer.
  • Some bumpiness comes with the territory when you are towing a trailer. A weight distribution system should help you smooth out the ride quality of your 2011 Nissan Frontier Towing a 3000 lb R-Pod trailer. Weight distribution systems are recommended when the trailer weighs more than 50 percent of the tow vehicle. So you would be a good candidate for a WD system. Weight distribution does what it name implies and distributes the tongue weight of your trailer to the front axle of the tow vehicle...
