Description
Overview:
The Spike Outer is a Genuine Husqvarna part for petrol chainsaws in the 50-60 cc class, built to restore firm, predictable control at the cut. Made from durable steel with rigid teeth, it provides a secure bite into the timber so the saw can pivot smoothly and stay stable under load. Designed specifically for Husqvarna models such as the 550 and 560XP, it matches the original mounting points for a precise OEM fit. By anchoring the saw body to the workpiece, it improves accuracy, reduces wandering, and helps manage kickback tendencies. Identified by MPN 577014003 (also 577 01 40-03), this outer bumper spike is suitable for professional forestry, arborist, landscaping, and farm users who need reliable performance and consistent handling.
