W01-358-9978 Firestone Trailer Air Spring Bag 1R12-668 Goodyear Air Suspension Replacement
Product Description
Truck air springs utilize compressed air for elastic support, replacing traditional leaf springs. They consist of a rubber airbag, piston, and air lines. Adjusting the air pressure to achieve variable stiffness effectively cushions road impacts, improving ride smoothness, load adaptability, and cargo protection, while also reducing chassis wear and noise. Their advantages include light weight, adjustable ride height, and effective shock absorption. Widely used in heavy-duty trucks, trailers, and high-end commercial vehicles, they balance comfort and economy, becoming a core component of modern truck suspension systems.
