When you understand the benefits and features of every type of suspension, it will help you make an informed decision for choosing the right suspension for your trailer. 

Understanding the basics

What you should know is that a trailer suspension plays a critical role in maintaining balance, stability, and overall ride quality. It consists of various components that work together that absorb the vibrations and shocks and keep the trailer steady. 
Through this, you can minimize the wear and tear on both the trailer and the towing vehicle. Trailer Suspension Repair Services ensures that your trailer moves on the road without any issues.

The importance of suspension in trailers

Before we go deep into various kinds of trailer suspension, it is very important to understand why suspension is so important in trailers.

Also, the suspension system in your trailer is a combination of springs, tires, linkages, and shock absorbers. They perform three main functions,

  • Improving the trailer stability
  • Maximizing the friction between the tires and road 
  • Making sure of a smooth and balanced ride.

The most important component of the suspension system is the spring and with time it has evolved into many kinds of suspension systems.

Four kinds of trailer suspension

Let us have a look at the kind of trailer suspension.

Leaf spring suspension

Leaf spring suspensions are among the oldest forms of suspension systems that are still being produced today.  They are best for light trailers and are very good for absorbing shocks. Although, they are not recommended for heavy-duty use. 

Trailing Arm suspension

The trailing arm suspensions were taken as the landing gears of the aircraft. Afterward, it has become a popular choice for all ground vehicles, including oof-road trailers as well. 

The suspension of this type features an arm or link that is connected between the axle of the trailer and the central point of the chassis. 

The arm is located at the front of the trailer stub axle and bearings. Well, the use of independent trailing-arm suspensions on the trailer enables every wheel to move vertically easily, and independently. This results in a far more comfortable ride. 

Air suspension

Since the 1980s, the air suspension has been used in ground vehicles. This is a modification of the trailing arm suspension. 

The steel springs in a trailing arm suspension have been restored by textile-reinforced rubber bellows. These are also known as air springs or airbags. 

The weight of the trailer is supported by air springs instead of steel springs in a trailing-arm suspension. Air suspensions are a good option because they work well on all kinds of terrain. However, you’ll need an air compressor or air cylinder to adjust the pressure based on the terrain.

Rubber Suspension

A rubber suspension is a lightweight and straightforward type of suspension system. It uses a torsion arm attached to the trailer frame. 

Inside this arm is a heat-treated inner bar surrounded by three or four rubber cords. When a load is applied, the inner bar rotates, causing the rubber cords to compress and provide resistance. 

This setup functions similarly to a traditional sprung axle, but the rubber cushioning prevents metal parts from touching each other, reducing wear and tear.

Factors to Consider When Choosing a Trailer Suspension

When selecting a trailer suspension, there are several key factors to consider: load capacity, ride quality, adjustability, and cost.

Load Capacity

One of the most crucial factors is the load capacity of the suspension. You need to ensure that the suspension can handle the weight of your trailer’s load. This includes any extra weight you might add in the future. 

It’s wise to choose a suspension with a load capacity that exceeds your current needs to ensure safety and stability. This extra capacity provides a margin of safety and can accommodate any immediate increase in load weight.

Ride Quality

Ride quality is another important consideration. You want a suspension that delivers a smooth and comfortable ride, even on bumpy roads. 

Think about the types of roads you’ll be traveling on regularly. If you often drive on rough or uneven surfaces, you’ll need a suspension that can handle these conditions well. 

A good suspension system will reduce the impact of bumps and potholes, making your ride more comfortable and less jarring.


Adjustability is also key when choosing a trailer suspension. Being able to adjust the suspension to suit different loads or road conditions can be very useful. Some suspensions offer more adjustability than others. 

For example, many coil spring systems come with toe and camber adjustments, which can help improve tracking and reduce tire wear. 

Also, you can easily swap out coils for ones with different weight ratings. Choose a suspension that offers the level of adjustability you need to meet your specific requirements.


Cost is another major factor to consider. It’s important to find a suspension that fits within your budget but still provides the necessary features and performance. Consider both the initial cost, mobile trailer repair, and potential future maintenance expenses. 

While a more expensive suspension might have a higher upfront cost, it could save you money in the long run by offering better performance and durability. 

Although a cheaper suspension might save you money initially but could end up costing more over time due to more frequent repairs or replacements. It’s important to weigh the pros and cons of each option and make an informed decision based on your needs and budget.
