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 3 ways. First, you can retrofit the trailer with a crossmember. Second, you can build out the trailer frame. Third, you can use 2" x 3" steel tubing to connect the 2 Timbren suspensions together using the built-in 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 2 separate units, each containing rugged steel arms and 2 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" x 3" holes make it easy to reinforce your trailer's frame by adding 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, 4" drop spindle (straight model shown) 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 hole accepts 2" x 3" tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2" x 3" steel tubing through the hole on each suspension unit and then bolting the tubing into place.

Timbren Axle-Less Suspension vs. 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 vs. 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 3 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" x 3" tubing (sold separately - available at most weld shops) through the integrated holes in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with 3 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 3 bolts to attach the suspension to the side of the frame. And you also have to use 2 or 3 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 2 distance measurements (A and B) are within 1/8" of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, 1/2" bolts (not included).

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 Leaf Spring Suspension


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.

Really cool work!

Review from a similar Axle-Less Suspension in Trailer Leaf Spring Suspension


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.

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.

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 Leaf Spring Suspension


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 Leaf Spring Suspension


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.

Fast service from etrailer sending me my Timbren kit. They are always very helpful. Unfortunately it looks like UPS mishandled one of the 3 boxes and had to re-tape it all over. I just rcv'd the shipment, so I will have to open the box when I get home and make sure everything is inside. This is no fault of etrailer, just the shipping companies these days.

Review from a similar Axle-Less Suspension in Trailer Leaf Spring Suspension


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 Leaf Spring Suspension


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 Leaf Spring Suspension


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 Leaf Spring Suspension


After a great deal of research, I ultimately chose the Timbren long arm kit to replace the torsion axle under my teardrop trailer. My initial impression is that there is simply no comparison between the two. It now rides better, pulls better and handles better than I could have imagined. The Timbren axle system is incredibly well built and is much more confidence-inspiring. While the spring rate closely matches my trailer weight, the components are much more rugged and robust. The spindles, bearings and brakes are rated at double the capacity of my old axle which gives me great peace of mind. I pull my trailer, both on and off road, anywhere it will fit and the long travel and heavier components are a game-changer for my travels. Installation, while requiring a bit of forethought, was otherwise straightforward and methodical. Documentation available from etrailer and Timbren, is second to none. Instructions were clear and concise with drawings and detail taking the major guesswork out of the equation. Even though, due to the odd frame design of my trailer that required a bit of work to adapt, I ended up making some frame stiffeners, the adaptation was as simple as it could possibly be. I've ordered from etrailer in the past and they were 100% accurate on this order as well. I ordered the Timbren kit without backing plates and hubs due to the requirements of my trailer and etrailer suggested, explained availability and supplied all of the components I needed. They truly a stress-less bunch of folks with an extraordinary website. I'll no doubt turn to them again...

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.

It was a very straight forward install, it goes pretty smooth if you take your time, double check your layout, Make sure of your bolt sizes (length) before going to the store. If you plan the project, don’t rush, its not a race, it goes really good. I spent about 10 hours spread over two days by myself. I am just waiting for tires to arrive. All that said very happy with the product and etrailer. Will recommend for any axel/suspension replacement.

    When the Timbren Axle Less system part # TASR7KS02 is installed the center of the spindle will be 3/8 inches above the bottom of the trailer frame when unloaded. At full deflection (compression of the systems rubber springs), it will end up sitting 2-1/2 inches lower that that as well. So it would be then 2-7/8 inches above the trailer frame. I attached a diagram that has all of the dimensions of this system as well.

  • Determining Axle Location on 18 Foot Trailer with 7,000 Pound Axles
    It sounds like you are needing to determine the correct positioning of the axles on your 18 foot trailer. When determining an axle's position, the key is to make sure that they are located in a position so that roughly 10 to 15 percent of the total trailer weight is placed on the tongue. Doing this can take some trail and error, so you will want to mock up the locations for your suspension comonents until you know everything is correct. I have attached a great article that details this...

  • Are Timbren Axle-Less Suspension Systems a Good Option for a Custom Trailer
    The Timbren Axle-Less Trailer Suspension # TASR7KS02 is a great option for your custom trailer. This system is much easier to install than standard trailer axle/suspensions and there is virtually no maintenance for the suspension. The correct hub that will fit this is the Trailer Hub and Drum Assembly # 42866UC3-EZ. If you let me know what kind of brakes you are wanting (electric, hydraulic, or electric-over-hydraulic) I will be more than happy to help you find the correct parts. The...

    We sell the Dexter beam axles that are up to 3,500-lbs capacity, but we also sell axle-less suspension systems that have a capacity up to 7,000-lbs.

  • Will 8 On 8 Inch Hub Work With Timbren Axle-Less Suspension System
    Unfortunately, the Trailer Hub Item # AH60880FCOMP will not fit the spindles of the Timbren Axle-less Suspension System, Item # TASR7KS02. Like you pointed out, this is the only 8 on 8 inch hub option we have for you.

Please let me know if I can help you with any other questions.

  • Why Shouldn't Timbren Axle Less System be Used on Triple Axle Setup
    The problem with using the Timbren axle less with a triple axle setup is the lack of equalizers which distribute the weight of the trailer over uneven terrain like bumps evenly between the axles. With a triple axle Timbren Axle Less setup the full weight of the trailer would be on an individual axle at any given moment which would exceed the axle's individual capacity.

  • 7k Timbren Trailer Axle that Gives Lower Profile
    It's hard to give you an exact deck height you'd have with the Timbren Axle Less kits we offer like the part # TASR7KS01 as it depends on the wheel/tire size you use and frame height, deck thickness etc. But if you are looking for the lowest profile possible the 4 inch drop version part # TASR7KS02 is the kit for you. To give you an idea on overall height though this will put the center of your trailer wheel exactly 3/8 inch below the frame of the trailer. So you could calculate the diameter...

  • How to Determine Length of Axle When Rebuilding Trailer
    The axle length is actually going to depend on a few factors; the 83" width of your trailer is important, but you also need to add the width of the fenders or wheel wells to that if they add to that. From there you subtract the width of your wheels and the length of your two spindles. This will give you the necessary axle tube length. Another option is to forego the equation and instead use an axle-less system, the Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange...

  • Will the Timbren Silent Ride Raise or Lower My Trailer Height?
    It seems like the end goal for this is going to be to lower your trailer a little bit; if I'm misunderstanding what the end goal is here please let me know. I'll start this off by saying that the Timbren Silent Ride # TSR14KT01 is not an air ride system and there are no components that inflate or deflate, so it's not going to be adjustable in the manner that you're hoping. What the Silent Ride system will do is create a much softer ride for your toy hauler by using rubber springs to...

  • Parts Needed to Complete Axle-Less Trailer Suspension with 7000-lb Capacity
    I have a solution for you, but because the Timbren Silent Ride # TSR14KT01 requires through axles, you would not be able to use this for your trailer that does not allow for tube axles to be used. I recommend that you use 2 pairs of the Timbren Axle-less Trailer Suspension # TASR7KS02 (4" drop spindle) or # TASR7KS01 (regular spindle) to create a tandem axle trailer system-without the axles. The Timbren systems above have a 7000-lb capacity with each set, which when you use 2 sets, would...

  • Recommendation for Smallest Tire to Create Lower Deck Height on 7 Ton Trailer
    The best trailer tire for your setup is going to depend on the amount of axles that are on the trailer. This info is needed to ensure that the combined load capacity of all the tires will meet or exceed the 7 ton loaded weight of the trailer. For example a tandem axle setup would give you 4 tires so each tire by itself would need a load capacity of at least 3,500 pounds. For this type of capacity you are going to need at least a 16 inch tire and wheel. The smallest 16 inch tire we have...
