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.

  • Recommended Disc Brake Components for Nuwa Hitchhiker 5th Wheel Trailer Conversion
    For your Nuwa Hitchhiker 5th wheel, I recommend you start with the Kodiak 12" Hub-and-Rotor Assembly - 6 on 5-1/2 # KHR12D. For this assembly you will need the bearing kit # Bearing Kit # BK3-100. For your grease caps you will need # RG04-060 which come in sets. For your calipers, I recommend the Kodiak Disc Brake Caliper - Dacromet# KDBC225DAC along with the mounting bracket # KCMB12D and brake pads # K225CP. For your brake lines and your Electric Over Hydraulic actuator, I recommend...

  • 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...

  • How to Fix a Trailer Leaning Heavily to One Side
    The reason your trailer is heavily leaning to one side is because of the way it's loaded. From the picture, it appears that you have much more equipment on the right side than you do the left side. This uneven loading has caused the leaf spring to wear down quicker overtime further worsening the problem. Unfortunately, you really only have two options to fix the problem which would be to either reorganize how equipment is loaded on the trailer or replace the suspension components with...

  • 7k Timbren Trailer Axle that Gives Lower Profile
    It's hard to give you an exact deck height you'd have with the Timbren Axle Less kits we offer like the part # TASR7KS01 as it depends on the wheel/tire size you use and frame height, deck thickness etc. But if you are looking for the lowest profile possible the 4 inch drop version part # TASR7KS02 is the kit for you.

  • Availability of 6k or 7k Axles to Replace Lippert 3,500 lb Axles on Trailer
    Hi Chris; we do not have any 6,000 or 7,000 lb axles that match that length for replacement. The only thing I can offer is the Timbren Axle-Less Trailer Suspension - 7,000 lbs # TASR7KS01.

  • How Will The Spindle Need To Be Removed On a 7,000LB Torsion Axle?
    The Spindle # TRU37FR is going to be welded in place on your torsion axle. It will most likely need to be cut off and torched out due to the way your axle is clocked near the mounting bracket. Before you attempt to replace the spindle be sure to check the condition of the rubber inserts inside the axle as you may need to consider replacing the entire axle if there is to much free play on your axle. As we do not carry replacement torsion axles you might consider a Timbren Axle-Less system...
