Description
Overview:
This genuine Husqvarna spike (part no. 578 40 05 01, also referenced as 578400501) is a factory replacement for the Husqvarna 545 and 550XP/XPG chainsaws. Made from durable steel, it mounts to the saw body to provide a positive bite into the timber, helping you pivot the saw and keep steady control through the cut. The teeth help stabilise the bar at the start of a cut and when working around the hinge during felling or when bucking. Designed to match the original fit and geometry, it supports reliable performance for both professional users and keen DIY owners. Its robust construction stands up well to regular use, giving consistent grip and predictable handling in a wide range of cutting tasks.

Typical Applications:

The spike lets you set a stable pivot point, guide the cut line, and maintain steady feed pressure. It is useful when starting cuts on barked or uneven timber and when making controlled plunge cuts where accurate entry and stability are important.
