Husqvarna 521078901  Spring

The Spring stores mechanical energy to bear loads, and support impact in part components. Springs can either stretch or compress as a load is applied, according to their purpose. Springs will fail in response to excessive stress or force for what they are designed to handle. Failure in springs can deform other components in your machine. We always suggest purchasing replacement springs from a genuine OEM original parts dealer, like us, to ensure they fit exactly as intended for safe operation by the OEM.
