Description
Overview:
This strimmer head spring is a precision replacement for Honda brushcutters, designed to restore correct tension and smooth operation in the line head. Built from robust spring steel, it sits between the spool and housing to provide reliable compression for tap-and-go line feed. It is sized for a secure fit in compatible Honda heads, including UMK 425 LE and UMK 425 UE models. Key dimensions: inner diameter 34 mm (1.34 inches), outer diameter 39 mm (1.54 inches), height 27 mm (1.06 inches). Use it to resolve weak line advance, uneven feed, and head rattling caused by a fatigued or distorted spring. A practical service part for regular maintenance, it helps keep your brushcutter running efficiently during mowing, edging, and general clearing.
