The Role of Air Springs on Trailers

Air springs play a vital role in trailer suspension systems. They are a suspension component that uses compressed air to support the weight of the trailer and provide a smoother ride. Here are some of the key roles air springs play on trailers:

Shock Absorption: Air springs help cushion the trailer from road bumps and vibrations, minimizing the impact felt by the trailer and its cargo. This helps protect cargo from damage and ensures a smoother ride for the driver.

Improved Stability: By maintaining a consistent ride height, air springs help stabilize your trailer and improve its handling. This allows the tires to maintain better contact with the road, resulting in improved driver control and safer operation.

Load Support: Air springs support the weight of the trailer and its cargo. They can be adjusted to suit different load weights, ensuring the trailer remains level and balanced. This is especially important for trailers carrying heavy or uneven loads.

Reduced Maintenance: While air ride suspensions may require more maintenance than spring ride suspensions, they offer benefits such as improved ride quality and reduced wear and tear on your trailer and its components. Aerial trailer maintenance costs should be assessed against the potential cost of cargo damage during transportation
