The top plate measures 9.00 inches wide, while the piston width is 7.90 inches, delivering a stable load‑bearing platform. Each unit weighs 17.20 lb, offering a balance of strength and manageable handling during installation. Permanent engraved part numbers ensure traceability, and the 25 % stronger 4140‑grade steel studs guarantee secure attachment to the chassis. This air spring bag is built for heavy‑duty applications, making it suitable for a wide range of commercial trailers, dump trucks, and specialty equipment that demand consistent ride quality and durability.

Usage

Designed for on‑road and off‑road environments, this air spring bag excels in applications where load stability and ride comfort are critical. Whether you are operating a refrigerated trailer, flatbed, or a heavy‑load construction vehicle, the bag’s adjustable height allows you to fine‑tune suspension characteristics to match varying cargo weights. The durable rubber construction resists wear from road debris, temperature extremes, and UV exposure, ensuring long‑term performance. Installation is straightforward: the bag bolts directly into the existing mounting points, eliminating the need for custom brackets or extensive modifications. After installation, the air pressure can be adjusted via the vehicle’s existing air system, providing real‑time adaptability for changing load conditions. This makes the product an ideal solution for fleet operators who need reliable, low‑maintenance suspension components that can handle frequent loading and unloading cycles.
