Description
Overview:
The Knee Joint Assembly Kit 50cc is a genuine Husqvarna spare for the chain brake mechanism on Mark II professional chainsaws such as the 550XP Mark II and 545 Mark II. Built from robust, wear‐resistant materials, the knee joint links the front hand guard to the brake band system, helping ensure positive, repeatable brake engagement and release.

Designed for precise fit and alignment, it maintains the safety, reliability, and feel of the brake action on compatible Husqvarna models. Supplied as a ready-to-fit assembly, it helps reduce downtime and supports long service life when installed and maintained according to the saw manufacturer's guidance.
