SAF-Holland

Constructed for resilience in air-ride systems, this spring unit offers reliable load leveling and impact absorption under dynamic road conditions. A maximum height of 13.98 inches, a piston diameter of 177.80 mm, and a maximum outer diameter of 9.12 inches define its physical footprint and stroke capability, ensuring compatibility with smaller-bore configurations and tight installation envelopes. Classified under VMRS 016-008-001, it resides in the suspension air category, enabling technicians to align maintenance procedures with standard industry diagnostics and service intervals. Cross references such as FI W01 358 9471, GYR, and MID entries signal broad interchangeability with common fleets and repair shops, aiding quick sourcing and reducing downtime. The part’s role centers on maintaining ride height and saddle-load balance, which improves steering response, tire life, and overall vehicle stability in varied operating conditions. When fitting, verify the compatibility of end-fittings, mounting hardware, and available space around adjacent components to prevent interference during inflation cycles and ensure dependable long-term performance.
