Note: The Timbren Axle-Less suspension system may require additional support on your trailer. If your trailer does not have a crossmember above the spot where you want to install the Timbren system, you may need to reinforce the frame. You can accomplish this three ways. First, you can retrofit the trailer with a crossmember. Second, you can build out the trailer frame. Third, you can use standard, 2-inch steel tubing to connect the 2 Timbren suspensions together using the built-in square hole on each unit.


Ground Clearance

Ride on rubber with Timbren's Axle-Less trailer suspension system. This one-of-a-kind suspension consists of two separate units, each containing rugged steel arms and two strong, hollow rubber springs. Overall, the system safely and effectively absorbs road shock, minimizes trailer bounce and rattle - regardless of load size - and helps to protect your trailer's components and cargo. Built-in camber and toe-in keep your trailer tracking straight to minimize tire wear. Integrated hangers attach to your trailer's frame. And 2-inch holes make it easy to reinforce your trailer's frame by adding standard, 2-inch-square steel tubing (if needed).


The Axle-Less independent suspension system replaces your trailer's existing leaf spring suspension and can eliminate the need for an axle. The independent action of the suspension reduces roll when your trailer is cornering and allows you to maximize ground clearance and minimize deck height. Your trailer can have the same side-to-side clearance as your tow vehicle. And the low deck height makes it easy to load cargo from either the rear or the side.


Because you're riding on rubber, your trailer will ride smoothly and comfortably, whether you're navigating rocky terrain or highway asphalt.


Timbren Axle-Less Suspension Parts

Components

  1. The AEON progressive-rate main spring supports the weight of your trailer and cargo and easily absorbs road shock. It is constructed of heavy-duty, hollow rubber.
  2. The rebound spring minimizes trailer bounce, rattle and bottoming out. It keeps the suspension under constant tension and ensures that the main spring compresses and expands in a controlled fashion. And it delivers a smooth, stable ride - regardless of how much cargo is on the trailer.
  3. The trailing arm and integrated hanger attach the suspension to the side and bottom of the trailer frame.
  4. The control arm carries the spindle and the hub. It pivots on strong, long-lasting urethane bushings that never require lubrication.
  5. The EZ lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money.
  6. The hub is not included with this model.
  7. The built-in square hole accepts standard 2-inch tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2-inch steel tubing through the hole on each suspension unit and then bolting the tubing into place.

Timbren Axle-Less Suspension versus Leaf Springs

Leaf Spring Example

The Axle-Less suspension's progressive spring is a definitive upgrade over leaf springs. Although leaf springs deliver a stable ride when supporting a load, a trailer with leaf springs will bounce and rattle when it's empty or supporting a light or off-center load. On the other hand, your trailer can bottom out on bumpy roads if the load is too heavy. The AEON progressive-rate springs of the Axle-Less suspension always deliver the same reliable performance, no matter the load size. As more weight is added to the trailer, the springs compress and become stiffer, offering more support for heavy loads. And because they rebound more slowly than leaf springs, the AEON springs do a better job of absorbing road shock, thereby keeping your trailer from bouncing and rattling when you're carrying a light load. So with this versatile system you will enjoy a smooth ride whether you're towing an empty trailer or a hefty load.


Unlike leaf springs, Timbren's Axle-Less suspension units operate independently of one another. Each spring activates only when needed. This reduces roll and delivers top-notch performance, even when you're hauling off-center loads. When your trailer with leaf springs takes a turn, one side of the suspension compresses and takes on more weight, and the other side becomes looser and bounces. This causes rattle and can make the trailer lean to one side. But when your trailer with the Axle-Less suspension takes a turn, one side compresses and becomes more rigid to absorb the weight, and the other side expands to normal height to help steady the load and minimize bounce and rattle. The load stays better balanced, even if it is off-center.


Timbren Axle-Less Suspension versus Torsion Axles

Torsion Axle Example

Timbren's Axle-Less trailer suspension system is a great alternative to torsion axles. While both systems allow either side of the trailer's suspension to operate independently, only Axle-Less suspensions are actually separate units. Torsion axles still require a bar that spans the bottom of your trailer, whereas Timbren's system can eliminate the need for a thru axle - giving you the same amount of ground clearance from the front of your trailer to the rear. It also allows Axle-Less suspensions to fit any trailer width - unlike torsion axles, which have to be fitted to an exact frame width.


Axle-Less suspensions operate in a smoother, less stressful manner than torsion axles. Torsion axles use a twisting motion, where the bar inside the axle tube rolls against rubber cords or a rubber wall to create compression and resistance. The up-and-down motion of the main spring and the side-to-side motion of the rebound spring in Timbren's Axle-Less suspension work together to provide smooth, consistent compression - with no twisting - that results in a better ride and less stress on the suspension's components.


Installing the Timbren Axle-Less Suspension

Whether you are building a trailer or retrofitting your existing trailer with the Axle-Less system, you must make certain that the trailer's frame is both perfectly square and sturdy enough to support a heavy load without the aid of a thru axle.


Install Option 1

There are three ways to install the Axle-Less suspension. The easiest method, which is recommended if you are replacing axles on your trailer, is to install a piece of 2-inch-square tubing (sold separately - available at most weld shops) through the integrated hole in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with three bolts (not included).


Install Option 2

The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.


Install Option 3

The third method of installation is to bolt the Axle-Less suspension's hanger to the trailer's frame and to an existing crossmember that is in the area where you want to install the suspension.


With both the second and third options, you must use three bolts to attach the suspension to the side of the frame. And you also have to use two or three bolts to attach the suspension to the bottom of the frame extension, or crossmember. Both the second and third methods of installation will eliminate the need for a thru axle and provide the most clearance.


Measuring Diagram

Timbren's Axle-Less suspension units should be installed directly across from one another. Before mounting the units, measure back from the coupler and mark the frame to make sure that the two distance measurements (A and B) are within 1/8 inch of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, half-inch bolts (not included).

I installed these on a small jeep style camping trailer that I built. I plated my frame and also used the suggested two inch square tubing to tie them together. It rides very well, looks like it should be very durable, it's a simple design, simple to install, more economical than other independent systems, has less parts to go bad than other systems, I would highly recommend to any body using a trailer on rough roads!

We just drove 1200 miles mostly at 75mph. The axles work very well in all conditions, trailer ride very smoothly.

I mounted these axels on my off road trailer, this trailer has 37" tires (same as my jeep) tracks perfectly on the road at 60 - 70 mph, Last summer I pulled this trailer on the Rubicon trail were while on the rocks the lean angle was so extream my trailer turned over on its side, when I winched my trailer back on its wheels all the weight of the trailer was on one axel. Timbren Axle-Less trailer axels are so well built and strong nothing bent, everything stayed intact. There is no sag in these axels as well. I could not be more pleased with the Timbren axels.

Review from a similar Axle-Less Suspension in Trailer Axles


The trailer rides great down the road and no more worries about saltwater and rusty leaf springs. Not a cheap option but I’m very happy with the setup. When installing, just be sure to measure accurately and have sharp drill bits. A drill press type of guide also helps ensure correct drilling angles. The first picture is of a mounting gusset a local welding shop made. One is needed for each side and necessary to provide needed mounting strength-at least on my trailer frame. Pics 2 and 3 show the mounted suspension on one side of the trailer. Pic 4 shows the suspension on one side of the trailer with the axle attached and a separately purchased disc brake assembly mounted on it. Finally, pic 5 shows a 2” box channel between both suspension assemblies. Independent suspensions would have been nice, but I wanted to ensure trailer rigidity was maintained. So, after one year, so far, so good. It’s all smooth sailing down the highway.

Review from a similar Axle-Less Suspension in Trailer Axles


They have more pros than cons, but the second set I bought broke the flat plate that holds the spindle at about 8 months. The steel quality seemed less than I would expect since it basically peeled it back like a pop can as you can see in the pictures. Otherwise I like the clearance and ride. They last 2-3 years where the torsion axles I replaced would wear out in 4 months after driving down rough gravel roads. There is a grade zerk on the underside which I didn't realize until I bought the second set. That would have helped the first set last longer had I known about it.

Review from a similar Axle-Less Suspension in Trailer Axles


I used these axles in a different way than most would. I needed a trailer that was small, could handle tight switch-backs, carry 600 lbs and be light. I had this idea and as a retired design engineer I saw a great possibility in this axle. I have made four of these trailers now, one as a camp trailer, 2 for trail work for State Parks and one as a utility trailer.

Review from a similar Axle-Less Suspension in Trailer Axles


I am not a mechanic so Brandi was real helpful. Had to get some professional help to remove the old suspension and install the new suspension. The only drawback we ran into was the spindle did not extend out far enough to mount the tires in the normal way. We had to put the tires on backwards. It all worked out beautifully. Towed the trailer for over 1700 miles without any problems. Brandi was delightful to talk with and very patient with me. Her help was most appreciated. Sorry, I didn't take any pictures.

Review from a similar Axle-Less Suspension in Trailer Axles


Very exicited about these axels, I have been eyeing these for over a year. (Excellent service from etrailer, they had my parts to me in 1 day from the time of placing the order.) These axles seem to be well made and fit nicely with the Dexter hub and drum assembly and the 12" electric brake kit. I installed this all on a M1101/M1102 trailer frame after removing the factory axel assembly. I have not ran these on the road or off as of yet but will give another review at that time. The fit and finish are great and the packaging was good, a little banged up from shipping (missing 1 washer)

Review from a similar Axle-Less Suspension in Trailer Axles


Purchased 2 sets of the Timbren 1200 Axle-less systems for upgrading the suspension on an older 30' ft glider trailer. Single axle with small (13") tires made towing tough due to porpoising, dragging on drive entrances do to poor flotation; also German made and metric, no repair parts. GVW 2000 lbs equated to bouncy ride. Dual sets now allow the trailer to ride over bumps and sharp inclines easily, smoothly, little bounce on country roads; porpoising is history. My glider now rides securely, safely, quietly. Install time 4 1/2 hours (includes head-scratching). Results are outstanding, units are totally solid. Recommend the square tube interconnect, easy and quick - trailer frame was on the light side, so a precautionary fix. Clean look underneath. Ordered 5 wheels w/tires, very nice. Helpful neighbor so impressed he ordered a HD single set for his new DIY snowmobile trailer. Customer satisfaction 100%, from phone order, online support, product information, immediate shipping, install instructions, followup... HIGHLY RECOMMENDED!


Comments
I have just a little more to add regarding my purchase: Two sets, of the Timbren Axle-less assemblies, 1200 lb, and 5 wheels. I placed the order via phone, and whoever was on-call that day provided great answers and recommendations regarding the units, wheels and tires. At 31 feet, the trailer originally exhibited amplified porpoising on any bumps or dips in the road. Also bouncing and occasional sideways tipping due to the single axle. It made a lot of noise on my mountain community washboards. I speculated that the Timbren units would solve most, if not all of these problems and they have. Installation on my older 31 ft European ie, metric and no longer manufactured glider trailer was a mere 4.5 hours from removal of the old single axle to setting the trailer back down on its new assemblies. Instructions are complete, precise, useful and helpful. Appreciated. Little to comment on as installation was all straight-forward. I would like to describe the maiden voyage to the airport and back, but there is nothing to tell, other than it towed beautifully proper alignment instructions, and all that I viewed from the rear view mirror looked like a magic carpet ride. It rides over washboards and pot holes like a marathon hurdler, the 4-wheel independent suspension is great. Packaging: the shipping boxes all arrived in good condition, but the cardboard component boxes inside them... not so much. Most were ripped and open due to heavy components lightly surrounded with brown packing paper, just token amounts. Parts: all was accounted for minus a pair of spindle axle washers for one set, easily replaced at the local farm and ranch supply. No squawk, just an fyi. I am very pleased with your product and support, and was happy to leave a 5-star review with photos. The upgraded suspension was also a topic this past weekend at the glider port by those who regularly trailer their ships to various soaring events, some as far as a thousand miles away. My compliments to eTrailers, hope you can use my info,

Review from a similar Axle-Less Suspension in Trailer Axles


Timbren saved our RV road trip! The leafs on the axle on our 2018 Jayco TT came apart while driving in Maryland. We tried going to the manufacturer, but they were useless. Going to a RV mechanic meant being grounded for at least 2 months. Then we found Timbren. With the help of Timbren's excellent staff we purchased axle-less system through etrailer, who made sure we got as quick as possible. It came ahead of schedule, my husband installed the Timbren system and we were back on the road! The axle-less system is better than the original manufacturers. If you plan on taking your RV or TT farther than 100 miles GET THIS INSTALLED and get it through etrailer.

Review from a similar Axle-Less Suspension in Trailer Axles


Pleased with ETRAILER, will order here again. Not as happy with the torsion axle setup. 2 inch square opening for tying both axles together with your own 2" square tubing are not shaped to match 2x2x1/8 tubing. Grinding and welding of tubing required to make it fit. Also found the overslung stub axle left the end of the pivot arm without much ground clearance though the unit was intended and spec'd for atv tire off road use. A pivot arm with mounting pads top and bottom would be better and allow the user to choose high or low clearance use. I found the units were perfectly suited to offroad use once I fabricated new mounting pads and welded them to the bottom of the arms.


Comments
After a year of off road use, I couldnt be happier. My trailer rides smooth loaded or unloaded. No of that bunny hopp with leaf springs or rigid mount axles. The small rebound control snubber works perfectly! I modified my components for high clearance but the concept is sound, they work well. Great job Timbren!

Review from a similar Axle-Less Suspension in Trailer Axles


The order came in on time and the customer service at etrailer.com (Ashley) and Sean from Tmbren was outstanding. They both were very helpful in my choosing the right product for my needs. The axle less suspension's performance is absolutely superb. It vastly improves ride quality. I am using it on a teardrop camper that often goes on gravel roads and the raddling sound from the leaf axles was horrible. A couple of points to consider before you settle on the axle less suspension: keep in mind that you will lose some hight of the trailer. While you will gain clearance from the lack of the axle, the suspension will make the trailer sit lower than before.i had to lower my hitch by an inch to maintain the trailer leveled. Also it does appear to compress at higher rate than the leaf springs, which makes it softer but easier to reach it's limit. Overall this product is absolutely a must if you are looking to improve the safety and the quality of your towing.

Review from a similar Axle-Less Suspension in Trailer Axles


These units install easily, are well made, and perform great! The trailer doesn't bounce around like you see a lot of trailers do while traveling down a bumpy road. I traveled some unpaved roads with no issues. I am certainly glad I went axleless. I installed with 15" tires. Problem is I didn't go big enough. I intended to install on an existing trailer that I had. Changed my mind and built a new trailer. The new trailer came in heavier than I had planned. 2k pound capacity is now too small. I have to watch what I load the trailer with so I don't over load the suspension. I intend on buying the 3500 pound units when I have the money.

Review from a similar Axle-Less Suspension in Trailer Axles


I installed these on my single axle travel trailer to replace the axle and leaf springs. Weight savings was a wash with the required steel tube for added stability. I installed on an I-Beam using aluminum plate as a spacer. It took my friend and I 3 days to install everything. The hardest part was rerouting my black pipe propane line. I also had to install it just back of center due to a steel cross beam being in the way of the middle bolt hole. I replaced the brakes and hubs as well as the wheels to match the new hubs. Overall we've been super happy with this upgrade. The trailer rides a lot smoother. I'm not finding random screws on the floor after a long bump ride. We decided to do this after our leaf spring broke 2 times, 12k miles between. We were done dealing with a subpar suspension. I probably would not recommend doing this if your leaf springs are working for you. We put a lot of miles on our trailer. We aren't weekend campers.

    We have an option to replace the torsion axle on your 1996 Triton snowmobile trailer, but do not carry any torsion axles. Instead, the best option we have is a Timbren Axle-Less trailer suspension system which are simply bolted or welded so you do not have to worry about finding an axle that meets any specific measurements. They also offer you an improved ride compared to a traditional through-axle because the Timbrens work independently so if there is a bump on one side of the road it...

  • Axle Options for Fabricating Camper Trailer from 4 x 8 Utility Trailer
    The most important factor when selecting an axle is the weight capacity you need. You want to ensure your completed trailer's fully loaded weight is less than the axle capacity, or that it at least matches. Axles of a given weight rating will tend to have specific hub-face dimensions and spring center dimensions. You can use an axle longer than the trailer's width but spring centers must match your hangers. This really depends on all the details of your starting 4 x 8 trailer. Often 4...

  • Best Timbren Axle-less Suspension System for Tandom Axle 2,800 lbs Off Road Trailer
    Thanks for the picture of your trailer and truck. The Timbren Heavy-Duty Axle-Less Trailer Suspension 4" Lift Spindle - Off-Road Tires item # ASR35HDS02 you were looking at would work with your trailer but it might be a bit excessive as it is rated for 3,500 lbs for each system and you're wanting to add two for a 2,800 lbs trailer. I recommend the Timbren Axle-Less Trailer Suspension System item # ASR1THDS03. This Timbren axle-less system is comparable as it is rated for off-road tires...

  • Comparing Timbren Axle-Less 2K Trailer Suspension Systems with 4" Lift
    Great question! The Timbren Axle-Less Trailer Suspension System # ASR2KHDS04 has a standard size spindle which is why it is for regular tires. The Timbren Systems # ASR2KHDS03 and # ASR1THDS03 have longer spindles which can accommodate wider tires and the only difference between them is the slightly higher weight rating of the part # ASR1THDS03 (also known as the 1 Tonne by Timbren). All 3 kits are great options for off-road use because of the 4" lift, so it really boils down to what...

  • Replacement Axle for Dexter Torsion 2,200 lb Axle on 2005 Blizzard 10T Snowmobile Trailer
    For your Blizzard 10T Snowmobile trailer, the 2,200 lb GVWR with the Dexter torsion axle means we do not have a direct replacement. We do however have a better option that will work for you whether you have 78 or 79 inch hub face to hub face measurements. It is the Timbren Axle-Less trailer suspension system which is not dependent on a specific width measurement for fit and still includes the suspension so there are not leaf springs so it is somewhat like a torsion axle in that area. You...

  • Recommended Timbren Axle-Less Suspension For Off-Road Tear Camper Weighing 2000lbs
    I would be happy to help! For your off-road Tear Camper trailer that weighs in at 2000lbs I recommend the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Off-Road Tires - 2.2K # ASR1THDS03 you were looking at. This system has a 4" lift to give your tear camper an extra 4" of ground clearance when going over rough terrain, and has spindles that stick out further allowing you to run wider tires without having tire to frame interference. The Timbren axle-less is...

  • Timbren Axle-Less Trailer Suspension for Tear Trailer w/ Jeep Wheels
    Yes, you are correct the axle-less Timbren's are a great option. I recommend the Timbren Axle-Less Trailer Suspension System item # ASR1THDS03. These have a capacity of 2,200 lbs and are made specifically for off-road tires. The 4" Lift will provide greater ground clearance for your Jeep wheels. You will also need the etrailer Trailer Idler Hub Assembly for 3,500-lb Axles item # AKIHUB-550-35-K. These come pre-greased and have a 5 on 5 Inch bolt pattern. I have linked review videos for...

  • Hub Recommendation for Timbren Axle-Less System ASR1THDS03 with Jeep Bolt Pattern
    Typically the Jeep wheel bolt pattern is 5 on 5 inch. For an idler hub that will fit the spindles of the part # ASR1THDS03 and have the correct bolt pattern we have the # AKIHUB-550-35-K. This is a 3,500 lb trailer hub. The # ASR1THDS03 has a 4 inch lift built into it so it would work well for you since your Jeep is also lifted.

  • What Type of Tires to Use on Home-Built Off-Road Trailer
    The term regular tires when used in the context of Timbren axle-less suspension systems like # A20RS545 distinguishes this kit from one that can be used with off-road trailer wheels/tires, such as kit # ASR1THDS03. Do please note that for a fabricated trailer you will want to use only trailer wheels and special trailer tires. Passenger vehicle wheels and tires are built differently and are not suitable for use on a trailer. Trailer wheels usually have different offset (the distance they...

  • Alternative to Lifting Torsion Axles
    Unfortunately we do not have any parts that will allow you to lift your torsion axle. As you stated the lift kits we offer will not work with 3 inch tall brackets so while there is nothing I can offer you in terms of lifting your current axle you do have the option of removing that axle and using a Timbren Axle-Less Trailer Suspension System like the 4" Lift Spindle w/Flange - Off-Road Tires # ASR1THDS03 which is rated for 2,200 lbs and gives you 4 inches of lift.

  • Will Adding 4" - 5" Lift Axle Impact how a Trailer Tows
    Installing an axle that gives you more height on your trailer isn't necessarily a bad thing. The most important thing to remember is that too much height can cause your center of gravity to sit high enough that crosswinds and corners at higher speeds could cause adverse effects to your towing experience. With that being said, 4" - 5" of lift alone shouldn't be enough to make your trailer dangerous to tow. If you were to try lifting your trailer much more than that though is when you could...

  • Trailer Axle Compatibility with 5 on 5 Inch Hubs for Trailer Upgrade
    For your trailer you will actually need to change out your axles. The spindles you mentioned are not compatible with any of the 5 on 5 inch hubs. All of the options for the 5 on 5 inch hub assemblies are for 3,500 lb axles with # L68149 inner bearings and # L44649 outer bearing. I've linked the page to all your options to assist. Then I've linked the page to all your axles that are compatible and you will want to determine the hub to hub dimension required as well as your spring seat...

  • Recommended Trailer Axle with 56-1/2 Inch Spring Center Measurement
    The closest standard trailer axle we currently have available to the 56-1/2 inch spring center length you are needing is one like the Dexter Trailer Idler Axle w/ Hubs # 20545I-EZ-72-10 that has a 58 inch spring-center-to-spring-center measurement. Another option you may want to consider is an axle-less suspension system like the Timbren # ASR1THDS03. This system will provide a smooth and quiet ride and can eliminate the need for an axle. The suspension units replace your existing axle...

  • 5 Lug Idler Hub Recommendation for 2,200 lb Timbren Axle Less Kit # ASR1THDS03
    The correct idler hub for the Timbren Axle Less kit part # ASR1THDS03 that you referenced with a 5 on 4-1/2 inch bolt pattern is the part # AKIHUB-545-35-EZ-K. These come pre greased to save a bit of time and energy.

  • Can Trailer Spindle Be Mounted Directly to Trailer Frame Instead of Axle
    I do have a potential solution for you, but a standard trailer spindle like the 2,500 pound # TRU27FR you referenced should not be attached directly to the frame. This would eliminate any kind of suspension system so the trailer's ride would be extremely rough, possibly to the point of damaging the spindle or wheel/hub assemblies. Standard trailer spindles like this also just aren't designed to be used in this manner, so it's not something that has been tested in an any way by the manufacturer....

  • Timbren Axle Less Kit that Can Fit Jeep 5 on 5-1/2 inch Bolt Pattern Hub
    The 3,500 Timbren Axle Less kits like the part # ASR35HDS05 you referenced actually have 6k spindles on them so for hubs you have to go with the higher rated setups which unfortunately don't have any options in the Jeep bolt pattern you need. Could you get by with a lower rated Timbren Axle Less like the part # ASR1THDS03 which is a 2,200 lb axle and has 3,500 lb spindles so the hub you mentioned # 84555UC1-EZ would fit.
