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!
