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.

Video Transcript for Timbren Trailer Suspension - Leaf Spring Suspension - TTRA1032 Review

Speaker 1: Today we're gonna take a look at the Timbren trailer suspension enhancement system for medium-duty trailers. These have a 7,000 pound weight capacity. These will improve your suspension, handling, and safety of your trailer. They provide additional support as needed so you always have a nice, smooth, comfortable ride. It'll allow the least spring ample movement while cushioning light loads, and these will become more rigid as more weight is added. This will help increase your stability, provide great performance, while hauling heavy loads, and it'll help raise the trailer ride high.These do work independently side to side, so it will help compensate for off center loads.

Helps reduce body roll when swerving and turning corners, and it will work to eliminate trailer sway. These also will work as shock absorbers, taking the brunt of any bumps and rough roads, which will help extend the life of your trailer suspension.Again, the specs on this part is their application is for medium-duty trailers, lowboys, fifth-wheel trailers. For tandem max applications it does require two kits. These are designed to work with a suspension system that is in good working order. Again, the weight capacity is 7,000 pounds.

One note I do want to mention is you do want to make sure not to exceed your trailer's weight carrying capacity.And this part will include everything shown here laid out on the table. The two hollow rubber springs, all the mounting brackets you need to install it and the hardware, and these do install directly onto the frame, welding and drilling required for installation. And it does have a nice set of detailed instructions that'll describe and show you how to install everything.But that should do it for the review on the Timbren trailer suspension enhancement system for medium-duty trailers with a 7,000 pound weight capacity.

  • Best Trailer Suspension Enhancement for Tandem 7,000 lb Axles
  • The SumoSprings Trailer Helper Springs - Single Axle - 3K to 8K - Underslung # TSS-105-47 will be a maintenance free option to help smooth out the ride of your trailer. These springs will act as shock absorbers and will progressively help with the load offering 1,000 lbs support at 50% compression. The Sumo Springs are a great option to help control the suspension. This will require 2 kits. The Timbren Trailer Suspension Enhancement System Medium-Duty Trailers 7,000 lbs # TTRA1032...

  • Recommended Air Suspension Kit for 13,000 lb Tandem Axle Food Trailer
  • 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...

  • Recommendation For Upgrading Equa-Flex Cushioned Equalizer
  • The Equa-Flex Equalizer, Item # LC279687, is already an upgraded equalizer so there are not many "next level" options. The Lippert Components Center Point Air-Ride Suspension Upgrade, Item # LC1565391, is an overall better system but not significantly so. If you need a smoother ride, you could add shocks like the Lippert Bolt-On Mount Kit w/Heavy Duty Shocks, Item # LC281281. The Timbren Trailer Suspension, Item # TTRA1032, could also be an option worth considering. If you...

  • 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...

  • Recommended Trailer Suspension Enhancement on 2017 Grand Design 30 Travel Trailer
  • The E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers # K71-652-00 will fit any system just like an equalizer regardless of the bracket, so this will be a good upgrade to take some of the bounce out of your trailer as it will absorb that shock. The shocks will assist to absorb more and won't be mounted to the area where the hanger protrudes from the frame, so there shouldn't be any alignment issues. Another option is to use the Timbren Trailer Suspension...

  • Will the SumoSprings TSS-106-40 Fit a Trailer with 5-1/2 Inches Between the Leaf Spring and Frame
  • 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. SuperSprings came to our facility for training and said that there...

  • 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...

  • 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....

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.

  • 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. You may find that the measurement is really 33 inches and if so you can use part # K71-652-00. The included shackles center to center measurement is 2-1/4 inches.

  • 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.

The springs become more rigid as additional weight is added. Installation on I-Beam trailer frames is detailed in the attached instructions. For a tandem axle trailer you will need to use 2 kits.

  • 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. For suspension enhancement to help support your current setup you would want the Timbren Trailer Suspension Enhancement # TTRA1032 or you would need to replace your current springs...

  • 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....

  • 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...

  • 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.

  • 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.

  • 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...
