Protect fragile cargo with an ultra smooth ride

When you’re towing fragile cargo, like horses or electronic equipment, you need the smoothest ride possible.

As the strongest air ride system on the market, the Dakota Air trailer suspension offers ultra smooth ride quality, while its durable design matches the extreme demands of a construction trailer.

Dakota Air trailer suspension is a custom solution designed to work with existing trailer axles as a retrofit option on trailers that use a traditional leaf spring — or similar — setup.

Wait, did you say air?

Did “air ride” make you do a double take? We get it. Many of our Timbren product lines for vehicles and trailers serve as air bag alternatives — relying instead on the power of our Aeon® rubber spring technology to create safe, stable rides for towing and hauling.

But some hauls call for an air ride system. Like when you’re towing fragile cargo.

The addition of air components makes for a stronger, more durable system, creating a smoother ride for your weightier applications.
