- Let’s talk a little about axles and suspensions. Leaf Spring Axles (double eye and slipper), Timbren, and Torsion Axles.
Application and Load determine the axle and spring system. To see the best results from any axle / suspension system. It’s important to load the trailer with the aim of getting the most wear out of that system. Your satisfaction with your suspension system. Will depend on the proper loading your Camp.
Double-eye leaf spring systems
There are several reasons that we prefer the Double-eye leaf spring system. Leaf spring axles come with most complete trailers. They consist of several flat, curved leaves stacked on top of each other. The two main types of leaf suspension are double-eye springs and slipper springs.

Slipper springs generally have a greater weight capacity, and fewer moving parts. So, there are fewer components to maintain. But, double-eye springs ride smoother than the slipper spring systems.
This is the most used suspension system due to its affordability. The parts are replaceable and need more maintenance than torsion axles. Yet, many prefer them over torsion for this very reason - they can be fixed.
If you have more than one axle on your trailer. Leaf spring systems are the most dependable for even tire wear and a steady ride. If you’re storing your trailer on uneven ground. Leaf spring will hold up better over the long term due to the independent nature of each leaf spring.
1. Leaf Springs, proven, proven, proven. (military, trucking industry)
2. It’s possible to perform extensive maintenance. Unlike torsion axles parts can be changed out.
3. Spring axles provide the most dependable tire wear, especially on multi-axle trailers.
4. They’re inexpensive and easy for the manufacturer to install. (this helps keeps your cost down)
5. Spring axles don’t need rewelding to replace an entire axle.
We are often asked why we don’t use torsion axles or Timbren axles-less suspensions,
Torsion Systems and Timbren Benefit’s;
1. Simple construction (fewer moving parts) usually means that repairs are seldom.
2. Maintenance free design. Lube your wheel bearings and that’s it!
3. No metal-on-metal contact points
4. Quieter during travel
If the axles are ever faulty. The entire suspension system must be replaced by cutting off the old one and installing new. Both systems are available in bolt on configurations.
It’s my opinion that the Timbren axle-less system is a glorified torsion axle. It works on the same basic principles. They use a hard rubber or urethane to provide tension / restriction of movement.
In the end it all boils down to the customers preference. We are here to please as well as produce the best trailer out there.
Well done! This is the best explanation and conclusion I've encountered on CZcams regarding the different kinds of suspension. Brilliant video!
Excellent video and awesome editing. This was really helpful to get a better understanding of the suspension system under the camps. Very cool to see those camps rolling along out in rough country!
USNERDOC thank you we are slowly learning.
i realize it's kinda off topic but does anyone know a good site to watch newly released tv shows online?
@Sincere Wilder flixportal :P
@Boston Killian thank you, I signed up and it seems like they got a lot of movies there :D I really appreciate it!
@Sincere Wilder glad I could help xD
Consider a different mounting of your rear spring. Changing your equalizer to the type seen on the rear of tri-axle trailers with the fork on one end and changing the rigid mount at back with a shackle mount.
When you plot the axle travel in a turn you find a more complimentary movement of the two. Not dragging the rear axle around a corner as is the practice now.
Better tire wear and better braking forces. Most useful on highway trailers.
Not my idea was more common on earlier travel trailers.
Thank you for explaining this. 👍🏼👍🏼
Thank you so much for this video.
Good video 👍🏻
Just subscribed. Thanks for sharing
One benefit of the axle less systems is the off road benefit. The bottom of the trailer can be flat and slide over obstacles, no low hanging axles.
Very helpful explanation
WELL DONE THANKS
I'm gonna need to lift my trailer lol
What are the rubber bumpers screwed to the frame underneath near the leaf sprung springs. I have two axel and there are four of these things. Als are these nessesary.
Are torsion axles an option? The spring set up gives the trailer a higher center of gravity.. much prefer lower profile.
Torsion axles are very popular on livestock trailers and some car hauler type trailers. Most other trailers will come under sprung rather than over sprung giving them a lower center of gravity while maintaining the simplicity of the leaf spring setup.
What would make a tandem axle enclosed trailer suspension squeak?
Rueben Taylor I’m assuming it’s a solid axle trailer not torsion? If that is the case it is most likely shackles. They do make greasable shackle bolts that will solve the squeaking. In the meantime you could spray them with wd40 or other types of lubricant. Keep in mind most lubricants will attract dirt to the area.
Torsion axles look like something i would have come up with if i were tasked with building a suspension system and as part of the challenge, the only materials available were two sizes of square tubing and some exercise bands. Absolutely asinine in my opinion.
Repeats himself over and over.
I've been researching on RV trailer suspension upgrade, and the slipper spring system, e.g. Roadmaster Comfort Ride, piques my interest. You said in the video's description that double-eye system rides better than slipper spring system, yet you have failed to provide any evidence or demonstration to illustrate that point.
You keep saying the choice of suspension depends on the application, yet you have failed to give examples of which suspension is suitable or best for what application. You keep coming back to the point that double-eye leaf spring system is cheap and easy to get parts anywhere, which makes it seems that it is your only criteria in choosing the double-eye leaf spring system.
With the exception of the axel-less suspension (good for rough grounds), I think your video does not provide much useful information. You have not really elaborated anything, other than keep repeating two points: double-eye leaf spring suspension is cheap and parts are easy to obtain. You don't need 11 minutes to say all that.
