Note: This Axle-Less system requires crossbeam support. If your trailer frame doesn't have a crossmember in place, you can retrofit it with one, or you can add a support by running a piece of 2" x 3" steel tubing through the square holes cut into these units. You could also add a steel reinforcement bracket to the inside of the trailer frame.


Get more ground clearance and a more comfortable ride when you're towing with Timbren's Axle-Less trailer suspension. This suspension system provides great shock absorption to comfortably get you where you need to go and to protect your precious cargo as you travel - even on rough pavement. With 2 independently operating units, you'll get better handling when making tight turns. And because this system eliminates your axle and has standard-height spindles built in, you'll get more clearance without having to raise your deck height.


Timbren Axle-Less Suspension vs. Other Suspension Systems

There are many suspension options for your trailer or camper. So, what makes Timbren Axle-Less different?


Leaf Spring Example

Axle-Less systems are a definitive upgrade over traditional leaf springs, in part because they allow you to do away with your thru-axle, allowing for maximum clearance. As you've probably noticed, having a leaf spring suspension means that your axle will always hang at least a few inches below your trailer's frame, resulting in limited ground clearance. This may make it difficult to navigate rough roads.


In addition, while leaf springs do a great job of supporting an even load, they may cause your trailer to bounce and rattle when it's empty or to bottom out with a heavy load. And they don't offer any type of shock absorption for a smooth ride - unless you have upgrades built in. With Timbren's Axle-Less system, gone are the days of dealing with these annoyances - this suspension is designed for a quiet, balanced ride, whether your trailer's fully loaded or empty.


Torsion Axle Example

A torsion axle is a step up in terms of shock absorption, and it provides more clearance than a traditional, leaf spring suspension, but that crossbeam will still hang down some. And if your torsion axle gets damaged in any way, it can't be repaired - you'll have to replace the entire thing with a setup that matches your exact trailer frame width.


With the Axle-Less system from Timbren, you won't have a low-hanging axle beam to get in the way when you're driving on rough roads. The standard-height spindles on this setup will keep your deck height the same, so you'll get that extra clearance and still be able to easily load and unload your trailer. And the rubber springs and independent operation both combine to absorb shock and deliver a smooth, easy ride. In addition, the Axle-Less system can be easily maintained over time, and it will fit any trailer frame width, so you don't have to worry about potentially ordering the wrong size like you might with other systems.


Timbren Silent Ride Example

Another suspension upgrade on the market is Timbren's Silent Ride. This setup is a great option to reduce bounce and rattle because it has the same AEON rubber springs as the Axle-Less system. But the Silent Ride still requires an axle, so you won't get the same ground clearance or low deck height as you will with the Axle-Less suspension.


Timbren Axle-Less Suspension Parts

The Timbren Axle-Less suspension is designed with you in mind. All of the parts work together so you can tow your trailer comfortably - regardless of load size.


Timbren Axle-Less Suspension Parts Diagram

  1. The jounce spring supports the weight of your trailer and cargo. It easily absorbs road shock and is constructed of AEON heavy-duty, hollow rubber.
  2. The rebound spring delivers a smooth, stable ride - regardless of how much cargo is on the trailer. It controls the movement of the jounce spring to minimize trailer body roll, bounce, rattle, and bottoming out.
  3. The trailing arm with integrated hanger attaches 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 polyurethane bushings that never require lubrication.
  5. The E-Z Lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money compared to a traditional axle.
  6. The built-in hole accepts 2" x 3" steel tubing (not included) to add support to your trailer's frame. The tubing sits higher than a trailer axle, providing additional ground clearance.

Installing the Timbren Axle-Less Suspension

Measuring Diagram

The first step in installing the Timbren Axle-Less suspension is to make sure that the mounting points for each unit are directly across from each other. The easiest way to measure this is to mark the desired mounting points on your trailer's frame. Then measure the distance between these points and the center of your trailer coupler. These measurements (A and B) need to be within 1/8" to keep your trailer frame square.


Once you have your mounting points lined up, you'll be ready to install the system. Drill 3 holes into your trailer frame at the desired mounting points. Then bolt each unit to the frame with Grade 5, 5/8" bolts (not included).


Keep Your Trailer Frame Square

Because Timbren's Axle-Less system eliminates your trailer's thru-axle, you'll have to find another way to get the crossbeam support that keeps your trailer frame square. You have a few different options to do this depending on your application and how much fabricating you're comfortable doing.


Crossmember Installation

If you're building a trailer, the best option is to begin building with the Timbren Axle-Less in mind and include a crossmember where you want to install the units on your frame. You can also retrofit an existing trailer with a crossmember.


Steel Tubing Installation

If you don't have a crossmember where you want to install the Axle-Less system (and you don't want to add one), pick up a section of 2" x 3" steel tubing from a nearby weld shop. This tubing will serve as a support to keep your trailer square. It will hang only about an inch down from your trailer frame, providing more clearance than a thru-axle.


After you've mounted both of the units to your frame, you'll need to drill 3 holes into the steel tubing and into the built-in, square holes. Then, insert the tubing through the holes and secure it with 3 bolts (not included) on each side.


Reinforcement Bracket Installation

The last option is to fabricate a reinforcement bracket that can be attached to the inside of your trailer frame and to the Axle-Less suspension. It may be a little harder to fabricate a compatible bracket than to mount steel tubing, but you may get additional clearance with this method.

  • Replacement Options for 85" Lippert 4,400 lb Axle
    Hi John; what you have there is a Lippert 4,400 lb axle that is 85" long with a 68-1/2" spring center measurement. 4,400 lb axles are obsolete so you're looking at upgrading to a 5,200 lb axle. The closest thing we have is the Trailer Axle Beam with Easy Grease Spindles - 86-1/2" Long # e45GR. This would stick out an additional 3/4" on either side of the trailer which wouldn't be too much if you don't mind the tires sticking out a little further. You will also need to cut off the spring...

  • Replacement Axle Solution for 2020 Rockwood Geo Pro G19BH
    While we don't have your exact axle in stock we have a great solution with the Timbren Axle Less kit part # ASR5200S01 as a great solution that's available now. This is a 5,200 lb axle setup that's similar to the torsion setups but doesn't have a beam that runs across the trailer. I attached a review video for more info as well.

  • Trailer Axle with 92 Inch Hub Face and 80 Inch Spring Center
    I do have an option for you but we do not offer custom made trailer axles which it sounds like you are looking for because what you have is not common. The best fit option we have if the measurements that you provide are correct is the Dexter Trailer Axle Beam part # 8327864 which is 94" between the hub faces, 79" long between the spring centers, and has a 7,000 lb weight capacity. Please note the hub face measurement does not include the lug studs. If this is slightly longer than what...

    If you are wanting to replace your axles with traditional axles then the first step would be to find what your Hub Face (A) and Spring Center (B) measurements will need to be (see attached picture). From there you will need to mock up your trailer to determine what size you need of the following items: 4 - Double-eye springs 2 - Front hangers 2 - Center hangers 2 - Rear hangers 2 - Equalizers 8 - Shackle straps 14 - Shackle bolts 4 - Spring seats (if needed) 4 - U-bolt sets (8 U-bolts) 4...

  • What Tire and Wheel Size Fits Timbren Silent Ride Suspension TSR10KT02
    Timbren Silent Ride Suspension # TSR10KT02 is designed for 3 inch axles and those are usually rated for 6,000 to 7,200 pounds. So basically provided the tires are an appropriate size and capacity for the trailer you will be able to use them. On the low end (6,000 pound axle) that would be at least a 235/80-16 tire size. And on the higher end it would be a 235/85-16 or larger. I have included a link to all of the 16 inch tires, wheels, and tire and wheel combos we carry.

  • Can Timbren Axle-Less Trailer Suspension Systems Be Installed On A Forest River R-Pod-190
    Hi Hank, Having to add on 7" of material to make up the spacing from the frame to the wheel wells isn't really going to be the safest option for your R-Pod. You would need to either increase the height of the frame for the wheels to clear under the trailer like you'd see with a typical travel trailer or switch to a torsion axle in order to have the wheels sit in the wheel wells and still get the same benefits of a torsion suspension. Adding on to the trailer frame outwards to make the...

  • Axle Recommendation for Trailer Carrying 9,000 Lbs
    Since you mention that your trailer will max out 9,000 pounds, which I assume includes the weight of the trailer frame and all cargo, I recommend going with the Timbren Axle-Less Suspension, # ASR5200S01. I spoke with my shop manager regarding whether he felt using the 5,200 pound axles would be overkill. He strongly recommends going with an axle that has a higher capacity than the amount of weight that you plan to carry and feels that the 5,200 capacity axles would be a good choice....

    As long as the frame itself can handle the additional weight, you would need to upgrade all of the other components under that weight capacity including the coupler. I recommend using the Timbren Axle-Less Suspension - Spindle Only - Regular Tires - 5200 lbs # ASR5200S01. This will allow your to simply remove the existing suspension and axles and add a cross beam or add a piece of 2x3 inch tubing between the axles in the integrated holes.

The alternative solution that we have is the Timbren Axle-Less Suspension # ASR5200S01. This system is rated for 5,200 lbs and can be used as a single axle or you can use 2 for a tandem axle trailer. There are a few great things about the Timbren system. It increases ground clearance since...

  • Upgrading from a 3,500 Lb to a 5,200 Lb Axle On a Trailer with 80-1/2 Inch Hub Face Length
    The spring center and hub face measurements that you have are more synonymous of a 3,500 lb weight capacity which is why you are having a hard time trying to find an axle with 5,200 lb weight capacity. That said, I do have an option for you in the Timbren Axle-Less Suspension part # ASR5200S01 which has a 5,200 lb weight capacity and you don't need to worry about matching the spring center or hub face measurements of your existing axle. This option also has a unique rebound spring which...

  • Appropriate Axle Rating for Trailer Weighing 7680-Lbs When Loaded
    A trailer's axles must be rated for at least the maximum trailer weight, its GVWR, or gross vehicle weight rating. This is the most the trailer can weigh when loaded. Naturally it is advisable to have some safety margin too. The standard beam axles we sell have ratings up to 3500-lbs. Higher-rated axles are made, of course, but we do not ship them due to shipping size and weight restrictions. Two 3500-lb axles in a tandem axle set-up would not have enough capacity, but three 3500-lb axles...

    Hey David, thanks for reaching out again! I definitely hear where you're coming from and I don't blame you for not trusting your 4,400 lb axles. Whenever I've looked into parts for them everything seems to be a hodge-podge of pieces fitted together just to say something is rated for that 4,400 lbs.

  • Troubleshooting 2018 Pacific Coachworks SeaBreeze 16BB Trailer Wheel Clearance
    In order for them to give it a 4,200 lb capacity rating, the weakest component on the trailer has to be able to withstand that capacity so you most likely have a 4,200 lb axle. We do have the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 which will allow you to raise your trailer by the axle diameter plus the leaf spring stack. That will gain you the wheel well clearance. If you want to replace your axles and springs, I need to know some information on the measurements....

  • Best Trailer Axles To Use For A Spring Center To Spring Center Measurement Of 74"
    I do have trailer axles similar to what you are looking for in our Timbren Axle-Less Suspension Systems however, we do not offer torsion axles at this time. In order to recommend a proper replacement axle for your setup, I would need to know the weight capacity of the axle you are seeking. For a Timbren Axle-Less Suspension System, you would use part # ASR2000S02 for 2,000 lb. axles, part # ASR3500S05 for 3,500 lb. axles, or part # ASR5200S01 for 5,200 lb. axles.

    Hey Keith, welcome back! I do have a solution, but I'm sorry to say we don't carry torsion axles like the one on your 2006 Ranger boat trailer. What I can offer is a universal option like the Timbren Axle-Less Trailer Suspension # ASR3500S05. The Timbren fits any trailer width, and uses AEON rubber springs which act like a torsion axle. This particular model has a 3,500 lb capacity. I'm not sure what the rest of the specs are on your trailer but this would be a capacity reduction by 250...

    Hi Gerald; you can use an axle like the # e73SR but you want to make sure the capacity is high enough. Also, this is 86-1/2" long so it will stick out an additional 3/4" on either side. Since your spring center measurement is different you will have to cut off the spring seats and weld on # TRSS300 to match your measurement. We do not have an axle that is an exact match for your 85" length. Typically when you replace an axle you want to match the capacity and the length. I'm assuming since...

That being said, we do not carry any axles that match your measurements. The only replacement I can offer is the Timbren Axle-Less Trailer Suspension - Standard Duty # ASR5200S01.
