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.


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

The Timbren system includes brackets that will be bolted to the trailer frame above the axle. Hollow rubber springs are then 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.

Ask the Experts about this Timbren Trailer Leaf Spring Suspension

  • Suspension Enhancement Recommendation for Trailer with 7,000 lb Axles
    For a 7k axle like what you have we have the Timbren kit part # TTRA1032 which is rated properly and will do a great job to give you additional trailer suspension support, but the SumoSpring kit part # TSS-103-40 can only be used on a 3,500 lb trailer axle.

  • What Welding is Required to Install Timbren Trailer Suspension Enhancement System
    To install Timbren helper springs # TTRA1032 the included bolt will need to be tack welded to the top plate, the top plate then gets welded to the bottom of the frame above the leaf spring stack. The 3 lower brackets will need to be welded together to get 3 inches of space (unloaded) between the lower plate and upper frame bracket. Then the lower disc assembly gets welded to the u-bolt plate. I have included a link to the installation instructions with more information and diagrams. You...

  • How to Pick Out Leaf Springs for Trailer and Suspension Enhancement with 7k Capacity
    If you can get me the axle capacity of your trailer and the current lengths of your leaf springs I can determine which of our leaf springs would be the best choice. I was unable to locate that info. We have Timbren kits that are designed for adding additional suspension support like the part # TTRA1032 which can provide up to 7,000 lbs of additional support.

  • How Much Space Is Required for the Timbren Trailer Suspension Enhancement System TTRA1032
    I do have an option but the Timbren Trailer Suspension Enhancement System part # TTRA1032 requires 3" between the frame and axle/leaf springs so it won't work. I can't recommend you raise the frame from the axle to use these as the preload would not be correct. Instead, the SumoSprings Trailer Helper Springs part # TSS-107-40 or part # TSS-106-40 is what I recommend and you would actually lift the trailer frame from the axle to install these as they are designed to be installed with a preload.

  • Suspension Enhancement for Trailer with 7k Axles Similar to SumoSpring
    For 7k axle like what your trailer has we have a set of Timbrens that would work great with the part # TTRA1032 but SumoSprings does not make a kit for that high of an axle capacity. The Timbrens are a very similar design and would work great to provide additional suspension support.

  • How To Fix Trailer Leaning To One Side
    It is not uncommon for a trailer to lean to one side even from the factory as heavier appliances can be on the same side or there could be multiple slides on that side. In order to try and combat this issue there are options from SumoSprings and Timbren. The SumoSprings are made of a much softer material than the Timbrens so although they are better at retaining ride quality, they could still allow the trailer to lean. Therefore, the Timbrens would be the best option for leaning. I recommend...

  • Will the Timbren Trailer Suspension Enhancement System Help with Uneven Tire Wear
    Suspension enhancement will not help uneven tire wear on your trailer. Even with the Timbren Trailer Suspension Enhancement System, # TTRA1032, installed, all of the weight will still be placed on the axle. The only help these springs will provide is to give your trailer a little better ground clearance when it is loaded. If your tires are wearing unevenly, your axle might be overloaded. The only fix for this is to reduce the weight in the trailer. If you reduce the weight and you continue...

  • Cedar Creek Hathaway 5th Wheel Suspension Enhancement Recommendation
    The Timbren Trailer Suspension Enhancement System Medium-Duty Trailers # TTRA1032 that you referenced will give your trailer's suspension a noticeable amount of additional support. It will help level your trailer side to side as the additional support will reduce the sag on that side of the trailer. I'd recommend making sure that you have the correct rated leaf springs on your trailer and that they aren't worn out either.

    The SumoSprings Trailer Helper Springs part # TSS-106-40 will fit your trailer even though you only have 5-1/2" of space between the top of the leaf spring stack and the bottom of the trailer frame. The overall height of the kit 7-3/4" (Spring 5" + Bracket 2-3/4") will exceed your measurements but what you can do is take a bread knife and cut one or two of the coils off the SumoSprings until they will fit under the frame.

    It sounds like you are really unhappy with the ride you are getting out of the Keystone toy hauler. There are a couple things you can do to get a much better ride. If you measure between the axles, it should be the distance center-to-center with the wheels and tires off the hub.

  • Recommended Timbren Suspension for Trailer With Roughly 1000-lb Load
    Usually when a trailer is bouncing around a lot behind tow vehicle, it starts with an improperly loaded trailer that has too much tongue weight and weight that is not properly distributed. Typically a trailer should have 10-15% of the total weight on the tongue of the trailer; you can measure your trailer's tongue weight with a tongue weight scale like the Sherline # 5780. Your tongue weight should be in the 200 to 270-lbs range using the 10-15% guideline (when fully loaded). When it...

    To assist with the stability of the trailer, an air suspension system will give you the support you are seeking for off center loads as well as offering a smoother ride and support for off center loads. For this system, I recommend the Lippert Components Center Point by Trailair Air-Ride Suspension Upgrade - Tandem Axle # LC1565391. This system also raises your trailer about 2 inches to give you additional clearance. If you want suspension support but don't want the air system, you may...

  • Can Higher Capacity Leaf Springs be Used on a Trailer Weighed Down by a Bobcat Tractor
    I do not recommend using higher capacity springs because that will give you a stiff ride. Also the different springs may require a different hanger orientation and since the hangers are welded on this is a professional job since the old ones have to be cut off and new ones welded on. Even if you added the higher capacity springs, the axle and tire capacities will not also increase so you could easily overload the trailer. With a load on the trailer, it is going to compress the springs....

  • Where to Measure 3 Axle Trailer to Determine Weight Capacity
    Sounds like you are trying to figure out the weight capacity for your 3 axle trailer. It is nearly impossible to determine leaf spring capacity based on dimensions. But you can determine axle capacity by measuring. Since your axles are 3 inches in diameter it would seem that they are 6k to 7.2k rated axles.

  • How Much Clearance Should be Between Tires and Fenders on Unloaded Trailer
    It all depends on how much the suspension travels but I would say unloaded you would want at least an inch from the tops of the tires to the bottom of the fenders. Keep in mind though that over time the springs will flatten out some, as much as half an inch, so keep that in mind years down the road. You could also add some suspension enhancement, # TTRA1032, rated for 7,000 pounds, which will help with support and ride quality. And it will prolong the life of the suspension. For a tandem...

  • 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....

  • Adding Shocks or Helper Springs to a Trailer to Go Off Road
    To answer the last question first, trailer axles move not just up and down but front to back a little as well; especially when there is more than one axle. Having shocks at an angle is more ideal for that type of set up than ones mounted straight up and down. So between the Equa-Flex and the shocks I would go with the shocks for your purposes. Lippert has 2 shock kit options. First is # LC281281 for 3 inch diameter axles. And second is # LC281255 for 2-3/8 inch diameter axles. Another...

  • Will Higher Capacity Trailer Leaf Springs Provide a Smoother Ride
    You could go up in spring capacity if you wish, but it won't increase the capacity of your trailer. You'll still be limited to the capacity of whatever the lowest rated component is. Using springs that are rated higher than the load applied to them will result in a rougher ride. Be sure to replace both springs on a given axle at the same time. For a smoother ride, you'll be better off using properly rated springs. If you don't already have radial tires, switching from bias-ply will further...

We have the E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers # K71-652-00 or the Lippert Equa-Flex Cushioned Equalizers - 3K to 6K # LC279687.
