Air Ride vs. Spring Ride Suspension: Which One Does Your Trailer Need?

When you request a trailer quote, one of the questions you'll see is whether you want air ride or spring ride suspension. If you've never had to choose before, it's easy to guess. Here's what the two actually mean and how to pick.

What suspension does

A trailer's suspension sits between the axles and the frame. It absorbs bumps, holds the weight of the load, and affects how much vibration your cargo feels on the road. The two common types do that job in different ways.

Spring ride

Spring ride suspension uses steel leaf springs, the stacked metal strips you can see above the axle. It's the simpler, more traditional design.

Strengths

• Simple and durable, with fewer parts that can fail
• Generally easier and cheaper to maintain
• A solid fit for heavy, rugged loads that aren't sensitive to vibration

Tradeoffs

• A rougher ride, since the springs transmit more of the road to the cargo
• Less forgiving with fragile or sensitive freight

Air ride

Air ride suspension replaces the steel springs with air bags that cushion the trailer, and the air pressure adjusts to the load.

Strengths

• A smoother ride that reduces vibration and shock
• Better protection for fragile, sensitive, or high-value freight
• Handles both light and heavy loads comfortably because the air pressure adjusts

Tradeoffs

• More components, including bags, valves, and air lines, so there's more to inspect and maintain
• Often costs more than a comparable spring ride trailer

How to choose

Start with what's inside the trailer.

• Fragile, sensitive, or high-value freight like electronics, glass, medical supplies, or packaged goods: air ride is usually the safer choice.
• Heavy, durable freight like building materials, bulk goods, or equipment: spring ride often does the job at a lower cost.
• Not sure, or mixed loads: tell us what you haul and how often, and we'll help you pick.

Suspension mostly matters for hauling. If you're leasing a storage trailer that stays parked on your lot, you generally don't need to think about it.

Where this applies

Suspension choice matters most for dry vans. Our quote form asks about it when you select a 48' or 53' dry van, so you can tell us your preference right away. If you're still deciding on a trailer type, see our guide to dry vans, liftgates, and flatbeds, or browse the fleet.

Keep it running

Whichever you choose, a well-maintained suspension lasts longer and keeps the trailer road ready. Our mobile maintenance team comes to your yard or site, so you don't have to bring a trailer in to get it checked.
