The Breakdown: Trailer Suspension

For many of our clients, suspension for their trailer is often not considered. It’s simple to use spring hangers, coils, springs, bolts, and shock absorbers? ?… But is it really that easy? It’s actually much more complicated than you imagine. It involves knowing the fundamentals of a trailer’s suspension , and in addition, matching the proper suspension for your trailer’s purpose. This article will explain all you need to know about suspension for trailers.


An suspension device is constructed to connect the wheels and brakes directly to the body of a trailer. It also assists in absorbing the physical force caused by the roads. In addition, it has to reduce noise while still allowing for controlling the vehicle. If you have any queries regarding which trailer suspension will be the best fit for your requirements, please give us the number.

Leaf Springs

The leaf springs are continuously being manufactured in massive quantities. They’ve been around for over a century They’re still capable dealing with the impact of the rough roads. Lightweight trailers typically make use of “slipper springs.” It’s an arrangement of springs where the front leaf is connected to the pivot point. The back portion of the leaf glides easily against the insides of a box made of metal. Both are light, inexpensive to purchase, and easy to set up. However, the downside to both of them is they’re intended for heavy-duty use.

However, for use in heavy-duty the leaf springs are positioned through bolts that connect the main eyes of the leaf on both sides. The rear part is connected onto a pivoting shackle that is connected directly to the vehicle chassis. These points could have simple bolts attached to the bolts or they may have bolts that are attached to them.

Leaf springs can accomplish impressive work by themselves. However, they tend to be affected by the shifting wheel camber, as either side is able to rise and fall as the wheels pass along the travel path. Any changes in the geometry of one side of the trailer significantly affects the geometry on the opposite side and can cause bump steer issues.

Trailing Arm Independent Suspension

In the case of this suspension, there’s no transfer of impact between the trailer sides from one to the other. Wheels are typically vertical through the entire travel. Additionally, they have a wider mobility. For those who plan to go off-road, its absence of the cross-vehicle axle beam makes an excellent ground clearance advantage.

Air Ride Suspension

It is generally a simple variation of the trailing-arm setup variant. Its spring load is generated via a metal coil, and the load is absorbed by a bag of rubber that is pressurized. This has many benefits to the user. These range from riding height and stiffness control and parking-levelling alternativesan ideal solution for those who ride on trailers.

Air ride trailers suspended can glide over the dirtiest roads. However, being able to make height or ride adjustments will require an onboard source of air, such as the air compressor, or Cylinder.

Independent Rubber Suspension (IRS)

IRS IRS which is also known as Independent Rubber Suspension provides a wide range of options for people who wish their trailer suspensions to be light and simple. It has several rubber parts which are incorporated into the hexagon tube that runs over the whole trailer. The system is bolted-on and doesn’t need any adjustments. It doesn’t require shock absorbers and allows the user complete of control on the trailer’s size and height.

The right suspension will require a complete understanding of what they are. Discussion with an expert or someone with experience in suspensions is an excellent decision before you make an ultimate decision.

Then, let’s get to the crucial facts. The best suspension to your needs is entirely dependent on the application you’re using. Camper trailers and caravans offer the option of using different suspensions but most machines or plant trailers are equipped with leaf springs. This is due to their general performance and price (as they’re a less expensive alternative).
