Dakota Air Trailer Suspension

Originally designed as a premium suspension for horse trailers, the Dakota Air system has evolved over the years. Its ultra-smooth ride is perfect for trailers carrying fragile cargo such as horses and electronic equipment. The durability of its material and design matches the more extreme demands of a construction trailer.

Trailer equipped with Dakota Air Ride Tailer Suspension

Air Spring

A single-convoluted low-frequency air spring provides a larger surface area to accommodate bigger loads. These are high-grade springs with a factory-installed internal rubber bump stop.

The combination of air spring, shock absorber and leaf spring help create a total suspension package ranging from 7,000 – 10,000 lb. capacities.

Shock Absorber

Timbren uses shock absorbers exclusive to the Dakota Air suspension. Rubber bushings inside these shocks minimize wear and tear. Each shock is capable of handling a minimum of 8,000 lbs. of tension to prevent over-extension of air springs.

The combination of air spring, shock absorber and leaf spring help create a total suspension package ranging from 7,000 – 10,000 lb. capacities.

Leaf Springs

Each Dakota Air suspension is equipped with a heavy-duty leaf spring for added stability and strength. This metal spring allows for a more compact design that is lightweight and strong. Easy bolt-on design requires no welding.
