HUSQVARNA 340 345 346XP 350 351 353 357XP 359 Anti-Vibration (AV) Spring

Anti-vibration (AV) spring fits Husqvarna 340, 345, 346XP, 350, 351, 353, 357XP and 359 chainsaws. These models use a spring-based anti-vibration system in which metal coil springs isolate the engine unit from the handle frame, absorbing the high-frequency vibration generated by the engine and cutting chain during operation. When an AV spring breaks, collapses or loses tension, vibration passes directly through the frame to the operator’s hands and arms, increasing fatigue and the risk of long-term hand-arm vibration injury. Fitting a replacement restores correct spring tension and effective vibration isolation between the engine and handle assemblies.
