Torsion vs. Leaf Spring Suspension Axles for Gooseneck Trailers

Torsion and leaf spring suspension axles are two forms of suspension. If you have researched either type, you have probably noticed that there are numerous contradictory opinions. However, the reality is that both forms of suspensions each has pros and cons. You will need to decide which system is best for you and your needs. We will discuss Torsion vs. Leaf Spring Suspension Axles.

Torsion vs. Leaf Spring Suspension Axles

Torsion Suspension Axles

Torsion suspension axles are mounted directly to the frame of the trailer. They have four rubber cords in the axle tubing that perform the following:

  • resist torsion
  • create suspension
  • provide shock absorption

As you drive, the rubberized cords compress and provide even wheel suspension, giving a smoother ride with less vibration.

The issue with torsion axles is that they do not have replaceable or repairable parts due to their attached construction. If your torsion suspension axles breaks, you will have to replace the entire suspension system. This is done by cutting off the old one and installing new. Not only can this be costly, but because each axle is separate from the other, there is no transfer of impact. For instance, if you hit a pothole, the full force will hit only that wheel which can cause more damage.

Leaf Spring Suspension Axles

Due to their affordability, leaf spring suspension axles are the most common form of axles available. This axle is composed of curved leaves stacked on top of each other installed below the axle. The leaf spring suspension contains an “equalizer bar” that connects both axles. This bar equally distributes force between the two axles. This will limit the damage that occurs as a result of potholes. Leaf spring suspension axles are fairly easy and inexpensive to replace, as they consist of many different components.

Unfortunately, leaf springs have their downsides as well. Leaf springs have so many components, so there are many things that can break. Unlike the torsion suspension, leaf spring suspension doesn’t have rubber cords to take the impact of a bumpy road, which can make the trailer ride a bit bumpy.

 

As you can see, Torsion vs. Leaf Spring Suspension Axles each have their pros and cons. You will need to weigh your options to determine which type of suspension is best for the hauling you will be doing. Contact Gooseneck Trailers with the link below for more information on our suspension axles!

One thought on “Torsion vs. Leaf Spring Suspension Axles for Gooseneck Trailers”

  1. It’s interesting that leaf springs are the most common suspension type available due to their price. It makes sense that since leaf springs are so inexpensive compared to the competition, it could be much more reasonable to have them put on a trailer. I’ll have to remember this for getting a new trailer whether it’s rented or bought because I don’t need the extra versatility or smoothness of torsion suspension.
