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.

Product is as described, installation was easy & performed as expected.

I ordered these to help reduce the rolling (tilting) of my 18' travel trailer that I use off-road. Also, I am hoping it will absorb some of the shock. I have added some photos of before and after installation. The installation was simple, I used 5/16" sheet metal screws instead of the bolts supplied. Time will tell if they work as expected.
As you can see from the photos, I have previously added an Etrailers shock mount kit to my axle. I made custom lower mounts that I welded to the axle and used the supplied upper mounts.

  • Troubleshooting Tire Rubbing at Full Suspension on 2004 Coachmen Viking Tent Trailer
    Other than flipping your axles, the only way to change the ride height of your trailer is to change the hangers unless your trailer suspension is really bad and has been very overloaded. It sounds like you research things like axle capacity so I'd be shocked if your suspension was that bad without you being very aware. If you want to change out your hangers, I've linked the page to all your options. Different shackle straps won't give you that kind of lift. There is only one suspension...

  • Timbren Trailer Suspension Enhancement System that Could Fit Tandem Trailer with 3,500 lb Axles
    For a tandem axle trailer the Timbren suspension kit part # TTRA1702 would be a great option to provide additional suspension support. It can provide up to 1,000 lbs of additional support per axle. Since you have a tandem setup you'd need two of these. This will get rid of suspension sag when your trailer is loaded which would raise it up in a sense, but it is not actually a lift kit. For an actual lift kit you'd want the part # RR23QX instead.

  • Recommended Upgrade for Utility Trailer Suspension
    The trailer will be bumpy for the dogs if you don't add suspension help. I recommend adding the Lippert Components Bolt-On Shock Kit w/ Heavy Duty Gas Shocks - 3,500-lb (2-3/8") Axle # LC281255 if you have 3,500 lb axle. If your axle is smaller than 3,500 lbs, then I recommend the Timbren Trailer Suspension Enhancement System Light-Duty Trailers 1,000 lbs # TTRA1702 to assist with your leaf spring suspension.

  • Picking Out Suspension Enhancement for 2018 Cargo Trailer that is 10 Feet Long
    We might have a suspension enhancement kit that could fit your trailer axles, but I would need to know the capacity of your axles. The kit you referenced most likely would be rated too high since it's for 3,000 to 5,000 lb axles. For lighter axles we have the part # TTRA1702 which was intended for 1,000 lb axles. If this would not work let me know what axle capacity you have and I'll see what we have that would work best.

  • 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...

    It sounds like you may need to look into the state of the suspension on your trailer. If there is so much movement that it has caused the tires to damage the fenders then something is not quite right.

  • Rear Suspension Enhancement System For a 2007 20 Lark Tandem Axle Enclosed Trailer
    Before you select a suspension enhancement system for your 2007 20 Lark tandem axle enclosed trailer you should verify the gross trailer weight of your trailer. Once you have determined the overall weight of your trailer when fully loaded, you can choose a suspension system that will effectively reduce sag and sway and provide a more comfortable ride.

  • 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.

  • Recommended Way to Improve Ride of Travel Trailer With 2,000 lb Axle
    There are options made specifically to address trailer suspension and smooth out the ride, though I can't see a longer, higher-rated leaf spring being the answer.

  • 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....

  • How To Determine If Timbren Trailer Suspension Enhancement # TTRA1702 Will Fit Single Axle Trailer
    The Timbren Trailer Suspension Enhancement System # TTRA1702 is 2-3/4" tall with no load on the spring. This particular system is designed to mount to the frame with the included bracket(see image) and when the suspension compresses the axle will push into the spring. You will need to measure the distance from the top of the axle to the frame to determine if this is an option for your trailer. It is okay to have the spring touching the axle or being compressed up to roughly 1/2". If your...

  • Recommended Trailer Bump Stop and Suspension Enhancement for Tandem Axle Trailer
    The amount of space needed is going to vary depending on the spring that you use. If you use the Timbren Trailer Suspension Enhancement System Light-Duty Trailers 1,000 lbs # TTRA1702, those springs are only 2-3/4" tall so you can get away with fairly minimal clearance. The other option would be the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 3K to 5K - Underslung # TSS-106-40 for underslung axles or the SumoSprings Trailer Helper Springs w/ Line Relocation...

    What happens to slipper springs is that over time they elongate and flatten out, particularly if your springs are considerably older. The most important measurement you mentioned was the 26 inches from the center of the spring eye to the end of the spring. Based on that the closest slipper spring we have that could work is the 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # SP-178275, which would work if you had a tandem-axle trailer.

  • Recommended Trailer Suspension Enhancement For Single Axle Utility Trailer Towing Polariz RZR
    I would start by checking that your current leaf springs are in good shape, and the the U-bolts are all tight. If all the suspension checks out then the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 3K to 5K - Underslung # TSS-106-40 would be the best option if your axle has a 3000-5000lb rating, or the # TTRA1702 if it has a lighter rated axle. Both options will help to absorb road shock when driving on rough roads, and minimize sway and body roll to give...

  • Should Bump Stops be Added to a Trailer when Using and Over/Under Conversion Kit
    Your StarCraft trailer would have to be overloaded and/or you would have to hit a pretty severe bump for the leaf springs to deflect beyond what they are designed for. SInce there is a chance this could happen, albeit a small one, having some extra protection would not be a bad idea. You could use Timbren springs # TTRA1702.

  • Can The Timbren TTRA1702 Work On A 48 x 96 Harbor Freight Haul Master Utility Trailer
    As the max working load of your 48" x 96" Harbor Freight Haul Master utility trailer is 1,720 pounds, the Timbren Trailer Suspension Enhancement System Light-Duty Trailers 1,000 lbs # TTRA1702 will have no issue working with it. However, this does need to have at least 3" of clearance as this will be the overall height of the spring and bracket once installed. I was unable to find the clearance listed anywhere so thought it was a good idea to let you know.

  • Suspension Enhancement Kit for Lighter Duty Trailer
    For the lighter duty trailers like what you have we have Timbren kits like the part # TTRA1702 which will help to stabilize the trailer when towing and level the trailer while absorbing some of the road shock. This will allow the trailer to track better and reduce some sway. We don't have shock kits for the lighter duty trailers at this time though.

  • SumoSpring or Timbren for 5x8 Karavan Utility Trailer
    For your application I recommend checking out the SumoSprings Trailer Helper Springs # TSS-107-40 because they are designed for an overslung leaf spring setup and SumoSprings tend to offer more forgiving support so it's more comfortable. This kit is rated for 3K - 5K axles and is 5" tall but SumoSprings has told us in the past that if one of their springs are too tall it's perfectly okay to cut it to the height you need and that won't affect the performance of the spring. Your photos didn't...

  • Recommended Solution to Help with Absorb Bumps on Small Utility Trailer
    I'm not necessarily sure that the air pressure of the tires is the main culprit here since the smaller tires have a higher air pressure to compensate for the lower capacity; you could absolutely go with a larger tire like the Loadstar ST175/80D13 Bias Trailer Tire with 13" White Wheel - 5 on 4-1/2 - Load Range C # AM3S140 to give yourself a higher capacity tire that doesn't require as much air. However, I think the light weight of the trailer also makes it a bit more prone to the bouncing...

    We don't offer airbags, like what is normally installed on a tow vehicle, for trailers. We do have jounce-style helper springs that may work for you.

    I do have an option for you but the Timbren Trailer Suspension Enhancement System Light-Duty Trailers part # TTRA1702 is not going to soften your ride. It would most likely do just the opposite of that. The only option we really have for you to soften your suspension would be to replace it with one of the Timbren Axle-Less Trailer Suspension Systems like part # A20RS545. The Axle-Less system uses a progressive-rate spring to help absorb road shock and provide a smoother ride. Unfortunately,...
