If you are in the market for a trailer, you may have noticed that there is an option between single-axle and tandem-axle trailers. But what is the difference between the two, and which is best for you? This is the age-old debate of single axle versus tandem axle trailers, and Cush Suspensions is here to provide you with the information you need to make the best decision for your needs. This blog post will discuss the differences between single and tandem axle trailers and the benefits each type offers.

Single Axle vs. Tandem Axle

What is a Single-Axle Trailer?

A single-axle trailer is supported by a single axle with two or more wheels connected. Single-axle trailers are commonly used for light-duty purposes such as transporting smaller items like boats, all-terrain vehicles (ATVs), and furniture. The single axle design gives the trailer a narrower width, allowing it to fit in tighter spaces and maneuver around tight turns.


The single-axle trailer is typically made from steel or aluminum and is often equipped with leaf springs or air suspension to support its load. The axles on a single-axle trailer can be easily replaced and are generally less expensive than tandem axle trailers, making them an ideal choice for light-duty applications. Single-axle trailers are designed to carry up to 4,000 pounds and can be towed by various vehicles, including cars, trucks, SUVs, and vans.

What is a Tandem Axle Trailer?

New ParA tandem axle trailer is a trailer that has two axles placed close together, usually spaced no more than 4 feet apart. This type of trailer is designed to provide additional support and balance when carrying heavy loads. The tandem axles offer more stability than a single-axle trailer. They can bear more weight, making them ideal for hauling heavier items such as boats, ATVs, and larger recreational vehicles.


Tandem axles also allow for excellent maneuverability as the weight is spread out over multiple axles, reducing the amount of strain on the trailer and providing a smoother ride. The most common type of tandem axle trailer is a fifth-wheel trailer, although other variations are available such as gooseneck trailers and tag-along trailers. No matter which style you choose, you can be sure that a tandem axle trailer will provide the durability and strength you need for your hauling needs.agraph

Benefits of a Single-Axle Trailer

Single-axle trailers are popular among many because they are lighter and more affordable than tandem. These trailers have less drag, which allows them to travel faster with less effort. This type of trailer is ideal for hauling lighter cargo, such as personal items or lightweight construction materials. They also offer a greater degree of maneuverability compared to tandem-axle trailers. They can fit in tighter spaces and corners and can be easily turned. This makes them perfect for hauling smaller cargo in tight spaces or navigating narrow roads.


The single-axle design also requires less maintenance. Because there is only one axle, it requires fewer components and parts, which means fewer things to repair or replace over time. The lack of multiple moving parts also means less wear and tear on the trailer. 


Lastly, single-axle trailers are more fuel efficient than tandem-axle trailers. This is due to the lighter weight and reduced drag, which translates into improved fuel economy. If you plan on hauling or traveling with your trailer, this can make a big difference. 

Benefits of a Tandem Axle Trailer

Regarding trailers, a tandem axle trailer offers more advantages than a single-axle trailer. Tandem axle trailers are built with two axles set side by side. This design is often called "tag-along" because the second axle follows the first. This extra axle provides excellent stability and support.


Tandem axle trailers are typically used for heavier loads such as boats and vehicles. They also offer a smoother ride because the weight of the load is distributed more evenly over the two axles. This helps to reduce stress on the suspension and improves overall traction. The extra axle also allows for larger tires, which can improve the braking performance of the trailer. Larger tires can help to slow down the trailer faster and make it easier to control when maneuvering around tight turns. 


Finally, a tandem axle trailer is much safer than a single-axle trailer. With two axles, the risk of a flat tire is significantly reduced; if one tire goes flat, the other can help carry some of the load. In addition, with two axles, it's less likely that the entire trailer will tip over or slide off the road in high wind or rain conditions.

When deciding between single and tandem axle trailers, you must consider the size of your load, the terrain you will be traveling on, and your budget. Single axles are more affordable and lighter, making them ideal for small loads and lighter terrain. On the other hand, Tandem axles are more expensive but can handle larger loads and rougher terrain.


If you have a large load and plan to drive off-road, then a tandem axle is the best option. This is because Tandem axles provide an extra layer of stability and support that single axles can't offer. On the other hand, if your load isn't as big and you don't plan on going off-road, then a single-axle trailer may be a better option for you.
