Description
Overview:
This Genuine Husqvarna Knee Joint Assembly is a precision metal linkage component used within the control mechanism of Husqvarna petrol chainsaws. It restores smooth, positive movement where a worn or damaged joint can cause play or sticking. Built for an exact fit, it integrates cleanly with existing linkages on models such as the Husqvarna 345 and 357XP, helping maintain consistent function under regular use. The assembly is engineered to OEM standards to match original geometry and tolerance, reducing downtime and ensuring reliable operation in both professional and domestic environments. If your saw is showing signs of slack or inconsistent response at the controls, replacing the knee joint assembly is a straightforward way to bring performance back to spec while protecting surrounding parts from accelerated wear.
