Extension Spring
SAF-Holland

An extension spring in heavy-duty assemblies provides axial tension, storing energy to maintain components in alignment and assist return movements after displacement. This particular spring is used to balance loads, absorb shocks, and ensure engagement of linked parts under varying road conditions. VMRS 059-010-011 places it within the extension-spring family used where reliable restoring force is required in mechanical linkages and actuators. Category 42827 identifies it as a component-level spring used in suspension and actuator applications. In practical terms, it is chosen for durability when subjected to cyclic loading, corrosion resistance, and compatibility with mating hooks or pins. It supports the proper spacing between assemblies, prevents rattle, and reduces wear on adjacent parts by maintaining steady engagement during travel. In installation, verify the spring rate, length, and end-hook configuration to match the intended mounting location, and inspect for fatigue after long service life in rugged environments. As part of a broader system, its correct selection contributes to safe operation and predictable performance in the field.
