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" 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 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 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).

Good application for custom axle set up that would not allow mounting to outer frame. Suspect I will need to make adjustment to camber as these mount to inside of frame with wheels in rather than outside of frame but shims were provided with kit. Also confirmed with mfg., Timbren, that these could be used in that configuration. Parts arrived in good condition in timely fashion. Did received two different type of tires but that was easily resolved with a single email. Good company to work with, competitively priced. 598251

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


Built a custom trailer to haul an ATV on some bad rural roads in Baja. I used the 2" drop axel-less suspension to allow for full size tires and wheels yet keep center of gravity low. Easy to install on exposed frame, but note that a required brace or 2" square steel bar may be needed and sourced on your own. The finish is not very durable and does not survive the normal bumps, wrench scrapes and scratches of installation; plan on some touch up once installed. Pay attention to the spindle clearance and wheel offset. 317250

A little bit pricey, at first. But in the long run they are cheaper. We used to bend or break an axle every 3 or 4 months. But we have had these a couple of years now with no problems. One thing that is nice is on a tandem axle set up you can get a flat and you just have to take the wheel off and run on 3 or 2 wheels without the hubs hitting the ground. 593458

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! 582196

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

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


Timbren Axle-Less Suspension - Spindle Only - Regular Tires - 5200 lbs Item # ASR5200S01 Looks great on empty trailer, idea is good, bad execution. When loaded tires "splay out" severely, excessive tire wear, obviously too much play in system somewhere. 584361


Comments
Excessive camber which causes wear on the portion of the tire tread closest to the trailer can be caused by a few different things. 1 The axle-less suspension system has a 5200 lb per set capacity, so youll want to be sure this amount is not being exceeded. 2 The surface of the trailer that the suspension member is added to needs to be an integral part of the trailer that should have NO give in it whatsoever. Any flexing of the side member there will throw off the camber of the tires. I have seen what you describe occur when the suspension system has been mounted to tubular steel that made up the edge of the trailer frame. In that instance, some angle iron was added to stiffen things up. 3 Its not required, but a piece of 2x3 inch tube steel of the appropriate length can be used as a beam connecting the two sides, utilizing the existing hole in the axle-less suspension member. This will help stiffen things up. 4 The suspension system should have included some shims that can be used where the spindle attaches to the suspension portion of the assembly. Using these shims can decrease the camber, but only if the points mentioned above are taken care of. Ive checked with Timbren regarding the above, and they concur.

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


I pull my Sea Doo GTX 300 (that means they are pretty heavy!) PWC's from Wisconsin to Florida twice a year. That said, this last trip to Florida caused me to bend the original straight axle on my trailer. Not fun. I ordered the Timbress Axle -less axles, and after a few hours of work on the trailer, they were installed, square and true. I immediately put the Sea Doos on the trailer to see how the trailer performs with the new axle-less system on it. one word: FANTASTIC!!!! I guarantee if I have to fix this issue again, I will use the exact same product. It is awesome! 736299

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


I was looking for a low profile axle system for my motorcycle trailer. The primary requirement was to be able to load my motorcycle by myself which required a low-profile trailer. With the 4" drop provided by Timbren, this setup turned out great. I originally intended on using ramps but after I swapped the leaf spring axle out with the Timbren, I found I was able to ride my motorcycle on/off without the need for the ramps. Originally, I was going to go axle-less but I found when torquing down the assembly to my frame it started to compress the aluminum rail. To take the pressure off the frame I added the 2" bar from axle to axle. Pulls smooth and effortlessly. I've had several people comment on the trailer height with one wanting to buy the trailer from me. This person worked at the local Honda Dealership. He thought it was a great design and I would imagine he's seen a variety of trailers come through his lot. The other option I considered was a torsion axle but I was looking for the lowest profile I could get. Therefore, cost was not a key factor. I also like the soft ride the Timbren system provides. Not sure if the torsion design would have been as smooth over bumpy roads. Regardless, I'm pleased with how this project came out. 352952


Comments
Its been a year since Ive installed the new axles on my trailer my comments above still hold true. Im very pleased with the ride quality of the system after a year. The trailer tracks true and has hauled many things other than my motorcycle. Even empty it doesnt hop around like the original stock straight axle did. No regrets on the purchase.

Review from a similar Axle-Less 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! 580744


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,

Excellent, helpful customer service sold me this product, and trust me when I say it's worth the price tag. Pulled the old axle and leaf spring off a 60's era Bantam and swapped out for this with a support bar in between. Bumped up tires to 315/75r16 BFG TA/KO's to match my rig and am amazed at how much better this trailer now pulls. Empty it wad bouncing all over the place with the old axle and leaf spring setup. Now I hardly even know it's there. Was very easy to install, took a couple hours but I am happy with how it turned out. A+++ product and customer service! 172019

They are GREAT! I put them on a small offroad trailer that has followed me all over some really rough roads in remote Oregon, Washington, and Idaho. They have performed flawlessly, helped the trailer tow extremely well, and were the single best upgrade I did to that trailer. Very much looking forward to another summer of exploring! Massive upgrade to the stock axle leaf spring combo, and I have had the opportunity to show it off to alot of fellow overlanders. I cant speak high enough of them. I also purchased a set of airbags for my vehicle which unfortunately have not held up terribly well. I have had to field repair one once already, and neither holds air terribly well. Truth be told they seem very underdesigned for the job they perform. From my super secret high tech pocket internet window.

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! 208571

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. 289894

It looks like a wonderful, well built system. The shipment was partial, turns out they forgot the rest. Customer service corrected the matter, still took almost 2 additional weeks to get the rest. The packaging for shipping - The suspension pieces should be packed individually not together. The box was torn in half and falling out, scratched up like it had fallen out of the box during shipping when it arrived. There were no installation / alignment shims or mounting hardware in the box, don't know if they were included and missing or they forgot that as well. I found no information on the paperwork for the inventory expected to be in the box. 424016

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


I think their axle-less design is very clever. The build quality of the suspension part looks good. I have heartburn over the spindle build quality. The spindle is mounted to the suspension and then the trailer wheel mounts on the spindle. The spindles I received are warped from welding. The plate that bolts onto the suspension does not mount flat due to this warping. I called Timbren. The gentleman that helped me was very pleasant. I described the problems and he said he would check his inventory and call me back. He did call me back and said they are all like that. He said get out the grinder and fix what you can and just tighten the bolts super tight, maybe the gap will go away. Really? Wow. The other problems are a LOT of weld spatter where the bolts are supposed to fit and they made a bend in the plate too close to the bolt holes so two bolt heads hit the bend and dont fit flat against the part they are supposed to hold together. Yikes! I am taking the spindles to a machine shop to fix them but I would not have ordered this Timbren stuff had I been warned before hand. So, fair warning. 100490


Comments
Your comments regarding the Axle-Less Suspension are greatly appreciated. To address the issues you have pointed out, we have carefully reviewed our assembly. While we did not come across any major issues, we did however discover a few areas where the quality could be improved, specifically in the areas you brought to our attention. The following improvements have been made to improve the manufacturing process: - Robotic welder gun re-programmed so that it stops from getting too close to the areas adjacent to the mounting holes of the outboard arm and control arm. This will minimize weld spatter. - The distortion of the flat plates is due to the high degree of heat generated during welding. We conducted experiments, changing the sequence of welding operations until we were successful in minimizing the distortion. We apologize if our customer service in addressing your concerns was insufficient at the time of your phone call. Timbren is an ISO 9001:2008 company with an excellent reputation for providing customers with quality products that are well-performing and easy to install.

It will require a cross frame member at the axle location or a 2 inch square tube (not included) to be added to...

  • Compatibility of Installing the Timbren Axle-Less Suspension System on an Aluminum Trailer Frame
    The Timbren Axle-Less Suspension System, # TASR7KS01, is compatible with aluminum trailer frames. I recommend that when installing the system that you use rubber shims the fit between the steel of the Timbren axles and the aluminum frame to prevent galvanic corrosion. The included hardware will work for the steel on aluminum application. The Timbren system will give you more under trailer clearance due to no axle tube under the trailer. The Timbren system's AEON rubber spring technology...

  • Recommended Disc Brake Kit For Timbren Axle-Less 7,000-Lb Trailer Suspension System
    We do have disc brake options for the Timbren Axle-Less Trailer Suspension System, part # TASR7KS01. The disc brake system I recommend is the Kodiak Disc Brake Kit, part # K2HRCM1337-9DAC. This kit comes with 2 full brake assemblies and has an 8 on 6-1/2 wheel bolt pattern. I have attached a helpful article that explains what is needed to add hydraulic disc brakes to a trailer you can check out.

    The Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange # TASR7KS01 is designed to be used with 8 lug trailer hubs part # 42866UC3-EZ. This is a 7k axle kit that would work well. For brake assemblies then you'd want the part # 23-324 for the left hand side and part # 23-325 for the right hand side and you'd be set.

  • Recommended Timbren Axle-Less Suspension with Parking Brake Operated by Hand
    I recommend the Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange - Regular Tires - 7K # TASR7KS01 which are the highest rated capacity axles we carry. With this you can use the Dexter Electric Trailer Brake Kit w/ Parking Brakes - 12" - Left and Right Hand Assemblies - 6K # 23-112-113 which will work fine with the 7K axle. Then you can use the Titan Breakaway and Parking Kit for Drum Brakes # T2385200 which will require you to make slight modifications for connection...

  • Weight Capacity of Timbren Axle-less Suspension Systems
    The Timbren Axle-less suspension systems are weight rated per axle. So the 7,000lbs is for the set. For your 13,000lbs trailer you would need to install 2 sets, so making your trailer a tandem axle. For example the 7,000lbs kit # TASR7KS01 has a quantity of one axle set. It has two pieces that equal one axle, a driver's side and a passenger's side. The # TASR7KS01 has a weight capacity of 7,000lbs. If you purchased a quantity of 2 # TASR7KS01, this will give you a weight capacity...

  • How Do I Determine the Axle Spacing on My Trailer
    I can tell you how you can measure this, but unfortunately we don't have a database with that type of information on each specific trailer. Because of the varying weights on different trailers you can get different measurements between the axles and they won't always be 33" or even 35"; I've seen some that are different depending on the size of the trailer. To find the axle spacing on your 2003 Forest River Cedar Creek, all you really need to do is measure the distance between the two...

  • Recommended Axles for Two Trailer Builds with 14K Capacity & 7K Capacity
    For your trailers, I recommend not using a steering axle because there are different requirements for them and your trailers don't need them. If you want to pursue the steering axle you will need to check with your local DMV for requirements. My recommendation is to use a single or tandem axle application for each trailer. If you want to use a single axle for your 7K trailer, I recommend the Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange - Regular Tires - 7K...

  • Replacement Axle Assembly for 6,000 lb Torsion Axle Bend Spindle on 2012 ATC Car Hauler Trailer
    If just the spindle is bent, we unfortunately do not have a replacement spindle compatible as we only have agricultural spindles # AS3000F and # AS6000F in that 6,000 lb capacity. Because you don't have the hangers and leaf springs for a thru-axle replacement, the best option we have is to replace your axle with the slightly higher capacity Timbren Axle-less system.

    Unfortunately the standard axles in our selection available have a maximum capacity of 3500-lbs. I do have a Timbren Axle-Less Trailer Suspension Item # TASR7KS01 option which would also replace your suspension. Timbren systems provide smooth, quiet, and safe rides without the need of an axle. Timbren systems also give you an independent suspension for better handling. It also has a 7000-lbs weight capacity. You would also need new trailer hub-and-drum assembly like Item # AKHD-865-7-2-EZ-K....

  • Can Brakes be Added to Timbren Axle-Less Trailer Suspension System
    Standard brake assemblies can be added to the Timbren Axle-Less Trailer Suspension Systems as long as the system on your trailer has the brake flange mounted. For example, the Timbren Axle-Less Trailer Suspension System w/ Brake Flange # TASR7KS01 are compatible with electric trailer brake assemblies like the Dexter # 23-105 for Left Hand and # 23-106 for Right Hand. You would then just add the Trailer Hub and Drum Assembly with 8 on 6-12 Bolt Pattern # 42866UC3-EZ. You will want...

  • Timbren Axle-Less System That Uses Hubs With 8 on 6-1/2 Bolt Pattern
    Since you need hubs with an 8 on 6-1/2 bolt pattern, the Timbren Axle-Less Suspension System you would need to use is # TASR7KS01, which is rated for 7,000 lbs. The hubs that fit these Timbren's are the Dexter # 42866UC3-EZ, and the brakes to go with would be the Demco Galvanized # 23511-10, which are 12" x 2" and fit 14.5" to 6" wheels. I've added links to a couple video reviews on these parts for you to take a look at.

  • Rating of Axles on 2008 Forest River Cedar Creek Silverback 33LBHTS 5th Wheel Trailer
    The 2008 Forest River Cedar Creek Silverback 33LBHTS has a specified GVWR of 13,830-lbs. Since it is a tandem-axle trailer this means it is likely to have a pair of 7K-rated axles (it should, anyway!). The stock tire size specified is LT235/85R16E. We do offer beam axles but not ones rated as high as 7K. This is due to shipping size/weight restrictions. Typically a 7K axle has a hub face dimension of 89-inches and a spring center spacing of 74-inches. You can contact Forest River...

  • Recommended Axle Capacity for 12,000 Pound Home Made Trailer
    In total you need enough capacity for around 12,000 pounds. Using tradition axles you can use 4,400 pound axles but those tend to be fairly expensive and replacement parts can be harder to find later. But the capacity of 3 of them would be 13,200 pounds which is a good place to be at. Another option is to use 6,000 pound axles. Making the trailer tandem axle instead of a triple would then be an option if you want. You can still have three 6,000 pound axles and the axles will be rated...

  • Can a Damaged Torsion Axle Be Replaced with Timbren Axle-Less Suspension
    Torsion axles use internal rubber cords to provide the suspension motion and they really are not practical to repair/rebuild. Certainly any axle that was damaged in an accident should be replaced purely for safety reasons. It is potentially possible that in certain cases the spindles can be replaced but that depends on the specific torsion axle and the specific damage. We do not offer torsion axles but we do have axle-less suspension kits from Timbren that completely dispense with the...

  • Trailer Axles and Electric Over Hydraulic Disc Trailer Brakes that Offer Best Ride for 14K Trailer
    For a 7,000 pound trailer axle I recommend a Timbren system, # TASR7KS01. This is actually an axle-less system with its own built in suspension. Since there is no axle beam connecting one side to the other it creates independent suspension at all the wheels. For 2 axles you would need 2 kits. For compatible disc brakes I recommend Kodiak dacromet disc brake kit # K2HRCM1337-9DAC. This kit is for 1 axle so to put brakes on both axles you would need 2 kits. For as much weight as you are...

We do not carry any through axles that will fit your application, but we do have an Axle-less system that will work for you and you don't need the dimensions listed above.

    We don't have a through axle anywhere near the length you mentioned for the width of your trailer. That would be a custom application for sure as manufacturers often have the 89 inch hub face to hub face as the longest measurement. Most states have a maximum width of 8 feet 6 inches, so I recommend you confirm with your state requirements. There will also be lighting requirements if over 80 inches. For your custom application, I recommend the Timbren Axle-Less Trailer Suspension System...

  • Determining Weight Capacity of Dexter Mobile Home Axle Using Serial Number

It is important to note that mobile home axles are really only designed and built to be used one time. If this is what you have on your trailer I highly recommend replacing it with a standard trailer axle. We don't have any axles...

  • How Much Travel Distance Is Recommended for Fender Clearance with Timbren Axle-less Suspension?
    You can absolutely use Timbren Axle-Less Trailer Suspension System on a custom trailer application, however the instructions state that the axle-less systems are not recommended for triple applications. With whatever system you end up using, you will want to leave a minimum of 4-7/8 inches of clearance above the tires for the suspension travel.

  • Can I Upgrade One Axle At A Time From 3500 To 7000 lb Capacity?
    I don't recommend upgrading one axle at a time. The capacity differences are substantial, and you will be limited to the weakest component. So the axle, the springs, the equalizer, the brake assemblies, and the hub/drum assemblies would all need to be accounted for. This axle capacity upgrade will require different brake assemblies, different hub assemblies, different suspension and different wheels based on the bolt pattern needed for this 7,000 lb capacity. There can be all kinds...

  • Will the Timbren Axle-Less Trailer Suspension System Work On a Keystone Montana with 7K Axles
    The Timbren Axle-Less Trailer Suspension System part # TASR7KS01 could be used to replace the axles and suspension on a Keystone Montana 5th Wheel Trailer. However, this would require changing the entire geometry of the suspension which is a rather complex install.
