Air Suspension Spring
SAF-Holland

Designed for heavy-duty air-ride suspensions, this component acts as a responsive load-balancing element that preserves ride height and dampens road irregularities across varying payloads. Its dimensions directly influence fitment and clearance: a maximum height of 13.98 inches, a piston diameter of 196.85 mm, and an outer shell diameter up to 10.12 inches. These specifications enable precise selection for compatible SAF-Holland suspension architectures, helping technicians match the correct bag to existing brackets and mounting interfaces. The VMRS classification 016-008-001 situates this part within the suspension air system, guiding maintenance planning, diagnostic procedures, and replacement intervals in fleets that rely on air-sprung legs for load distribution. Cross-reference references such as FI W01 358 9092, GYR, MID, TDA, and WWS catalogs indicate broad interchangeability with common parts inventories, facilitating quick sourcing during repairs. In operation, the spring supports consistent axle alignment, reduces chassis fatigue, and improves handling stability under dynamic loads. For service, verify compatibility with the vehicle’s intended load range, inspect mounting hardware for wear, and confirm there is adequate space around neighboring components to avoid interference during inflation and deflation cycles. Fleet applications span regional haul, heavy-duty construction, and vocational services where ride quality and uptime are critical.
