The heavy-duty Timbren Axle-Less system combines Timbren's standard 3,500-lb Axle-Less system components with 2,000-lb AEON rubber springs, giving you a suspension system that is perfect for your small, off-road trailer. It allows you to use parts that would typically only fit a larger trailer on your undersized trailer. Add brakes for improved control. Get greater ground clearance and increased durability by installing bigger tires and wheels. This makes the heavy-duty Axle-Less suspension system ideal for off-road use.


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. The spindle also includes a 4-bolt brake flange for simple mounting of trailer brakes.
  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).

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 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

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


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

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


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,

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


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

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.

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.

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


This suspension system did EXACTLY what I wanted. I replaced the leaf springs, axle/hubs on my small trailer. The new suspension improved the capacity, lowered the bed 4+inches, improved ground clearance and allowed me to rebalance the trailer all WITHOUT having to have any welding done. Everything needs to be measured very exactly and the alignment technique is fairly cumbersome and takes a bit of time. In the end, I have a quiet, steady, strong, low riding trailer.

  • Could Timbren Axle-Less Systems Work on a Boat Trailer that Sees Saltwater
    The Timbren Axle-Less System like part # ASR2KHDS01 would do just as well as a standard axle in saltwater. The powdercoat finish of the system will help to fight corrosion from salt water. Saltwater is very corrosive so any metal that gets exposed to it won't last forever. If you can, you should rinse off as much of your trailer as possible after being exposed to saltwater. This system has a 2,000 lb capacity. That means that both sides of the system together create a 2,000 lb capacity. For...

  • What is the Load Capacity of the Timbren Axle-Less Trailer Suspension?
    The Timbren Heavy-Duty Axle-Less Trailer Suspension - 2,000 lbs # ASR2KHDS01 has a total weight capacity of 2,000 lbs instead of an individual capacity of 2,000 lbs each. For something that will give you greater capacity for your cargo, I recommend the Timbren Heavy-Duty Axle-Less Trailer Suspension - 3,500 lbs # ASR35HDS05. The 3,500 lbs weight capacity of this system will be what allows you to move the cargo you plan to haul. I've added a link to a video review of this product...

  • Need Axle for Boat Trailer That Measures 73-1/2 Inches From Spring Center to Spring Center
    The closest option that we offer would be an axle with the spring seats welded at 74 inches but keep in mind that this could put your leaf springs in a bind if your spring center measures 73-1/2 inches. I have included a link to these axles for you. The only other option that I have would be to go with an axle-less system. I have included a link to those options as well.

  • Recommended Axle-Less System And Idler Hubs For Custom Trailer
    The idler hub assembly you mentioned, part # AKIHUB-545-35-G-EZ-K would work well with the axles you referenced. This hub has a 5 on 4-1/2 wheel bolt pattern and has a weight capacity of 1,750 lbs. This hub includes the bearings, races, seal, grease cap, wheel bolts and lug nuts. Since you are building a custom trailer the axles you referenced, part # ASR2KHDS01 as another great choice and a little less expensive. These axles have a weight capacity of 2,000 lbs, have a straight spindle...

  • Dimensions of Timbren Heavy Duty Axle-Less Suspension System # ASR2KHDS01
    The Timbren Heavy-Duty Axle-Less Trailer Suspension - 2,000 lbs # ASR2KHDS01 is an excellent system that bolts directly to the trailer frame. This removes the need for spring hangers, leaf springs, and even a thru-axle. It does require a 2 inch square bar (not included) that will span from assembly to assembly using the integrated holes. This assembly has spindles that are 1.063 inches diameter at the outer bearing and 1.378 inches at the inner bearing and 1.719 inches at the seal....

  • Are Timbren Axle-Less Systems Good for replacing Axles on a Boat Trailer
    Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR2KHDS01 are great options for replacing regular axles on a trailer. The only exclusion is that they should only be used for single or tandem axle set ups. Three axles are not recommended because with the Timbren system there are no equalizers between each set to help distribute the weight. I have linked a video review for you.

  • Timbren Heavy-Duty Axle-Less Trailer Suspension with 2,000 lb Capacity and Matching Hubs
    The Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR2KHDS01 have a 2,000 lb capacity and is compatible with Dexter Trailer Hub and Drum Assembly # 84656UC3-EZ which has a 6 on 5-1/2 inch bolt pattern. You can use the Hydraulic Trailer Brake Kit # AKFBBRK-35 with this set up as they have the matching 4 bolt mounting flange pattern and will fit in the 10 inch hub and drum kit. Keep in mind you wil need Mounting Hardware # BRKH10B with these assemblies. I have added links to video...

  • Is 2,000 lb Timbren Axle-Less Suspension System Able to be Used on Boat Trailer
    A Timbren Axle-Less system such as the 2,000 lb Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR2KHDS01 is definitely compatible with a marine environment such as the saltwater launching you are using your trailer for. There isn't a galvanized version of this system but it is steel and powder coated, and all you have to do is rinse it off after use, which you mentioned is a step you already take. The axle-less is also going to provide a much more stable, fluid towing experience...

  • Which Timbren Axle-Less Suspension System for On and Off Road Trailer?
    Great question. The standard 2K system # ASR2KHDS01 is for standard highway driving only. The Heavy-Duty 2K system # ASR2KHDS02 will be compatible with wider tires for more of the combination use you are seeking. The # ASR1THDS01 listed for Off-Road Tires has suspension that is more robust for up to 2,200 lbs and has a longer arm for a smoother ride over a rougher terrain. For your application, I recommend # ASR2KHDS02. It will handle better for your fair bit of highway driving...

  • Is the Weight Capacity of the Timbren Silent Ride Suspension Per Side
    The weight capacity of the Timbren Silent Ride Suspension for Single Axle Trailers or Timbren Heavy-Duty Axle-Less Trailer Suspension are both shown as a total figure, for the pair. Therefore, the Timbren Silent Ride Suspension for Single Axle Trailers part # TSR2000S04 has a total weight capacity of 2,000 lbs and the Timbren Heavy-Duty Axle-Less Trailer Suspension part # ASR2KHDS01 has a total weight capacity of 2,000 lbs. However, these systems should both be chosen based off the axle...

  • Flexiride 2000 vs Timbren 2000 vs Timbren 2000 HD Suspension for Off Road Trailer
    The HD versions of the Timbren kits like the part # ASR2KHDS01 are more intended for off road type use like what you'd be using so this is the kit you'd want. The spindles are actually designed for use with 3,500 lb hub/drums instead for added strength. The Flexiride system you have now is a torsion style spring that would not be as reliable in off-road situations so the Timbren would be a better route to go. You can use this kit with standard trailer wheels like the size you mentioned...

  • Hubs with 5 on 5 Bolt Pattern that Will Fit a Timbren Axle-Less Suspension System
    There are Timbren axle-less suspension systems that do not come with hubs so that you could add your own such as # AKIHUB-550-35-EZ-K. But the hubs with 5 on 5 bolt patterns that would also fit a Timbren system only accept up to 15 inch wheels. The other issue is that vehicle wheels are not meant to be used on trailers and often have an offset (mounting surface of wheel not in the dead center of the wheel) whereas most trailers take wheels with a zero offset. With that said the hub listed...

  • Replacement Axle for 2,000 Pound Dexter Axle on a Pop-Up Camper
    We have straight axles that are close to the measurements you have provided, see link, but the spring seats would have to be moved and none of them have brake mounting flanges. I propose a different approach by using a Timbren axle-less system # ASR2KHDS01. This system will provide the "axle" as well as the suspension in one unit plus the suspension part will not wear out nearly as quickly as traditional leaf springs because the rubber won't corrode. They are also set up for electric...

  • Is the Timbren Axle-Less Suspension System 2000 lbs Compatible with Electric Brakes
    You can use electric brakes with a Timbren Axle-Less Suspension System rated for 2,000 lbs, however, you would need the Heavy-Duty system, part # ASR2KHDS01. The Timbren Axle-Less suspension system, # A20RS545, that you referenced is not compatible with trailer brakes because it does not have a brake mounting flange at the base of the spindle. The Timbren Heavy-Duty system, comes with a brake mounting flange with a 4 on 4 bolt pattern which fits most 10 inch brake assemblies. The brake...

  • Recommended Products Needed When Building A Trailer To Use For Camping.
    As long as you know you will need to stay within the weight capacity of the axle-less system you are looking at, the Timbren system is a great option. I attached a chart that you can use that explains how to adjust the axle on a trailer to make sure you have the correct tongue weight. As the article explains it can be adjusted depending on the tongue weight you get. Since you said you are going to be traveling off-road occasionally you may be interested in the Timbren Heavy-Duty Axle-Less...

  • Replacement Trailer Axles for a 1964 Silver Streak Sabre Travel Trailer
    I do have an excellent recommendation for you but it isn't for a straight axle. Instead of a straight axle you can use a Timbren axle-less system that includes built-in suspension. They are essentially like torsion axles. If the trailer weighs 3,300 pounds dry then adding its carrying capacity would tell us the gross trailer weight which is essential in determining the correct axle-less system. For example if the trailer had a gross weight rating 3,750 pounds you could use a couple...

  • Recommended Idler Hub Assembly to Work With 2000-lbs Timbren Heavy Duty Axle-Less Suspension
    Yes. The Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR2KHDS01 is compatible with idler hubs as well as braking assemblies. Since the Timbren system uses an # L68149 inner and # L44649 outer bearing you can use the Trailer Idler Hub Assembly # AKIHUB-655-35-EZ-K and it will work just fine. The bearings, races and seals are all included in this hub assembly, so you'll have everything you'll need to get these installed. You will want to confirm that the bolt pattern of your wheels...

  • Replacement Axle for 1988 StarCraft Nova Tent Trailer
    We do have a couple of 2,000 pound leaf spring suspension axles available, such as the 60 Inch Dexter Trailer Axle Beam # T20BTR-6048 with standard spindles. When replacing the axle on your 1988 StarCraft Nova Tent Trailer, you will need to measure the hub face to hub face dimension as well as the spring center to spring center distance. I have attached an image that shows these dimensions on this particular axle. The hub face (A) refers to the length of the axle measured form the base...

  • Axles Less Suspension, Disc Brakes, Brake Controller and Brake Line Kit for a Carbon Fiber Trailer
    The Timbren system with the shortest distance between the trailer frame and the spindle of the axle with enough capacity for you would be the Timbren Axle-Less System part # ASR2KHDS01. That distance is 3-13/16 inches. For a disc brake kit that would work on this system you would want the Kodiak Disc Brake Kit part # K2HR35D-8. The smallest diameter wheel that will fit with this brake kit would be a 10 inch wheel. The lowest profile tire we offer to fit a 10 inch wheel would be the...

  • Recommended Timbren Axle-Less System with 5 on 5" Bolt Pattern Hubs for Overland Trailer
    I have a solution for you, and it sounds like you're looking for a Timbren system that can be used with 5 on 5 hubs that would allow you to use Jeep wheels. Unfortunately the Timbren # A12WS545 spindle does not have any hubs with that bolt pattern, so instead you would need to use the Timbren Heavy-Duty Axle-Less Trailer Suspension - Straight Spindle - Regular Tires - 2,000 lbs # ASR2KHDS01. If you're looking for a lifted system, the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4"...
