Air Spring Assembly
SAF-Holland

Designed for heavy-duty trailer axles, this air spring assembly delivers controlled load support and ride-height stability across on- and off- highway conditions. The unit integrates a reinforced bellows, end fittings, and mounting hardware that work together to adapt to changing load distributions, minimizing chassis oscillations and reducing tire scrub. With a nominal ride height of 8 inches, it maintains a consistent stance under varying cargo weights, improving steering response and braking stability. The component is a key element of the trailer suspension system, enabling dynamic load equalization that protects road components and enhances operator comfort. Its robust construction supports repeated duty cycles in commercial fleets, while the VMRS code identifies it within the suspension and ride-height subsystem for maintenance planning and replacement scheduling. Compatibility is broad within SAF-Holland’s trailer axle and suspension ecosystem, and it aligns with standard mounting patterns and bracket assemblies used across many highway configurations. In practice, technicians appreciate straightforward serviceability: check air lines for leaks, inspect the bellows for signs of cracking, and replace quickly to restore fully responsive performance. Category context highlights its role in the axle-suspension family, emphasizing highway reliability and long service life.
