Air Spring Assembly
SAF-Holland

Designed for rugged trailer-axle and suspension configurations, this high-coverage air-assisted unit supports sustained load-carrying performance across a wide range of fleet operations. The assembly delivers controlled vertical travel and damped air response to minimize chassis oscillations, which translates into steadier steering input and more predictable braking. With robust seals and reinforced fittings, it resists heat and fatigue from frequent cycle loads and helps protect wheel-end components from shock-induced damage. The VMRS placement 016-009-001 identifies it within the suspension and ride-height subsystem, while the category context reinforces its application alongside other trailer-axle components. Cross-compatibility with alternative ADZ- and SAF-Holland-branded accessories simplifies upgrades and field replacements. In real-world use, technicians monitor air pressure levels, inspect connectors for leaks, and verify mounting torque to ensure consistent performance through seasonal fluctuations and fluctuating cargo weights. This solution is well-suited for fleets prioritizing uptime, predictable ride quality, and long service life in demanding road conditions.
