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).

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.

Only been driving around on the axle-less system for about a week now and it has far exceeded expectations. I get better gas mileage, my trailer now sits like it was intended to, my trailer doesn't bounce like it used to, I wouldn't trade this axle system for any other. Just wish I would have known which outboard assembly arm my trailer needed with the axle-less system before I placed my order. Still not a problem though, plan on using the wrong outboard arm to build a different trailer. So far, a great product!

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


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


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...

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


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


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.

    For a wheel and tire that big your best option would be the Timbren kit part # ASR35HDS02 which is set up for wider tires and also has a 4 inch lift built into it. This is the same 3,500 lb capacity though. That being said we can only safely recommend using trailer rated wheels and tires wit this kit. For just a hub without a drum you would want the part # AKIHUB-655-6-K.

  • Timbren Axle-Less Suspension System Compatible with Jeep for Matching Trailer
    For the Timbren Axle-Less kit compatible with the bolt pattern of 5 on 5 like a Jeep, you would need the 2,200 lb capacity # ASR1THDS03. The spindles on the Timbren system are a little larger than their thru-axle counterparts, so the 3,500 lbs # ASR3500S06 will only fit larger hubs that won't have the bolt pattern you seek. Using # ASR1THDS03, you can then use the Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 5 # AKIHUB-550-35-EZ-K or the Trailer Hub and Drum Assembly...

  • Comparing Timbren Axle-Less Suspension Kits for Regular Tires vs. Off-Road Tires
    The 3500-lb Timbren axle-less suspension kits # ASR3500S06 (regular tires) and # ASR35HDS01 (off-road tires) differ in that the kit for wider off-road tires provides a 2-inch greater distance from the mounting point on the trailer frame to the hub face. This 8-inch distance versus the 6-inches for the regular tire kit means wider off-road tires will have the necessary clearance to avoid contacting the trailer frame. The linked image for off-road kit # ASR35HDS01 shows the wider 8-inch...

  • 3.5K Axle Upgrade for Off-Road Trailer
    To upgrade your axles to 3,500 lbs I recommend the Timbren Axle-Less Suspension System # ASR3500S06. This system has a 4 inch lift that will help to give you ground clearance when you go offroad. The etrailer.com Trailer Hub and Drum Assembly, part # AKHD-550-35-EZ-K, is compatible with this axle-less system and will give you that 5 on 5 bolt pattern that you were asking about. Keep in mind that your trailer weight capacity is limited by your lowest rated piece of equipment. Even...

  • Smallest Rim and Tire Combo to Use with the Timbren Axle-Less Trailer Suspension # ASR3500S06
    As long as I am understanding you correctly I believe I have a solution for you. Sounds like you want to use the smallest overall size wheel and tire you can fit on the Timbren Axle-Less Trailer Suspension # ASR3500S06. What really matters is overall wheel size and not just rim size so bear with me since there are no 10 inch rim options that would work for you. A 13 inch wheel is the smallest you can go with that will allow everything to work. For that I would recommend the wheel and...

  • 2020 Aliner Expedition Suspension Upgrade for Dexter 3,500 lb Torsion Axle
    Based on the specifications that Dexter gave me for your axle, your axle is a 3,500 lbs torsion axle. We do not carry torsion axles, so the best upgrade for your trailer would be an axle-less suspension system. The axle-less system will be far easier to install and set up compared to a traditional straight-axle and leaf spring suspension system. It also provides more ground clearance and better ride quality. Since there is no axle connecting them, it allows the springs to absorb road shock...

  • Timbren Axle Less Suspension System Recommendation for Older Aliner Camper

  • Dimensions of 3,500 lb Axle-Less Trailer Suspension System
    The dimensions - which you can see in the accompanying photo - are accurate for both systems. The # ASR3500S06 has a 4 inch lift spindle but the dimensions of the unit are the same as # A35RS545 which has a straight spindle; it also has idler hubs with a 5 on 4-1/2" bolt pattern. The other difference is that # ASR3500S06 has no hubs and but will work with hub and drum assembly # 84656UC3-EZ or idler hub assembly # 84545UC1-EZ. I've added links to video reviews of these parts for you...

  • 3,500 lb Timbren Axle Less System Recommendation for Trailer with 4 inch Lift
    Yes, we do carry a Timbren Axle Less system that has a 3,500 lb capacity and a 4 inch lift. For that you'd want the part # ASR3500S06.

  • Will Timbren Axle-Less Suspension Fit a 2000 Prowler 5th Wheel Trailer
    If your trailer has just 2 regular 3,500 pound axles now then using Timbren Axle-Less system # ASR3500S06 is an option. It is not recommended though for triple axle applications. The hubs you have now might fit. They will need to use inner bearing L68149 and outer bearing L44649 and a seal with a 1.719 inch inner diameter to fit the spindles on this system. If you need to also replace the hub/drum assemblies then you can use # 84546UC3-EZ. You can go to a larger size tire and wheel...

  • How To Add Larger Tires to a 2016 Coachmen Forest River Clipper Pop Up Camper For Use Off-Road
    The correct Timbren Axle-Less Trailer Suspension for you is going to be part # ASR3500S06 because it offers the 4" lift that you will need to clear larger tires on your pop-up camper. It looks like the wheels on your 2018 Subaru Outback Wagon have a 5x115mm bolt pattern which is the same as 5 on 4-1/2" so you will be able to reuse the hubs/drums and braking assemblies you have now.

  • Options to Provide Lift on 1967 Aristocrat Lo Liner
    While it is feasible, it is not the recommended way to add lift. Instead, what you can do is replace your hangers with longer ones, or go with a Timbren axle-less system. You will get 4" of lift by using # ASR3500S06, which has a capacity of 3,500 lbs, or a similar unit to replace your axle's capacity. I've added a link to our selection of hangers as well as each of our Timbren systems for you to take a look at.

  • Recommended Axle-Less Suspension System for Haulmark TS6X12DS2
    We do have an option for you, but do not carry any axles of that specification. Instead, for your Haulmark TS6X12DS2 I recommend the Timbren Axle-Less Suspension System, which are simply bolted or welded so you do not have to worry about finding an axle that meets any specific measurements. You can also get one with a straight spindle or a lift spindle: - Timbren Axle-Less Trailer Suspension System - Straight Spindle Only - 3,500 lbs # ASR3500S05 - Timbren Axle-Less Trailer Suspension...

  • Availability of Dexter Axle with 45 Degree Drop to Add Ground Clearance to Trailer
    I may have a solution for you, however we do not currently have any standard Dexter axles available that feature the kind of spindle lift you are looking for. I instead recommend looking into an Axle-Less System from Timbren, which can eliminate the need for an axle altogether. We do have systems available, such as the 3,500 Pound # ASR3500S06, that feature a 4 inch lift to provide improved ground clearance. I have attached a short video demonstration on this system so you can get a...
