Products Application
Anti-Vibration System Restoration
Direct replacement when the original AV rubber buffers become hardened, cracked, or lose elasticity from age and exposure to oil/fuel. Restores the saw's factory vibration-damping performance, reducing operator fatigue during extended cutting tasks and preventing excessive wear on other components .
Professional Chainsaw Maintenance
For high-hour saws used in demanding forestry and arborist applications, regular inspection and replacement of AV buffers is recommended. Worn buffers cause increased vibration that can lead to numbness and fatigue in the operator's hands.
Chainsaw Restoration & Repair
For professionals and collectors restoring Husqvarna 435, 440, and 445 series saws, the complete buffer set provides all necessary AV components. The comprehensive set simplifies restoration and ensures consistent vibration damping across all mounting points.
