SYOWADA 12pcs 25-2 Trimmer Head Spools Replacement for Stihl Head Cover 25-2 FS90 FS100 FS110 FS120 FS130 FS55 FS80 FS83 FS85 String Trimmer with Trimmer Head Covers Spring Eyelet Sleeve

What It Is

This is a 12-pack replacement kit for Stihl trimmer heads using the 25-2 system, including pre-wound spools, trimmer head covers, springs, eyelets, and sleeves. It’s designed for semi-automatic bump-feed heads on Stihl curved-shaft trimmers.

Fitment & Compatibility

Before buying, confirm your Stihl model uses the 25-2 head cover system. Compatible models include FS55, FS80, FS83, FS85, FS90, FS100, FS110, FS120, and FS130. This is an aftermarket kit, not OEM Stihl. The spools accept 0.095-inch (2.4mm) trimmer line. Measure your existing head cover diameter (approx. 2.5 inches) to verify fit. Not compatible with straight-shaft models or other head systems like 4-line or SpeedFeed.

Key Things to Know

• Quality concerns: At 3.1 stars, multiple reviews cite brittle spools that crack during installation or first use, and covers that don’t snap on securely.
• Installation difficulty: Moderate. You must disassemble your existing head, replace the spring and eyelet, then wind line evenly. A vise or clamp helps hold the head.
• Pre-wound spools: Save time but check line tension—some arrive loosely wound, requiring rewinding.
• Kit completeness: Includes 12 spools, 2 covers, 2 springs, 2 eyelets, and 2 sleeves. Covers and springs are the most common failure points.

Should You Buy It

Skip this kit if you need reliable, long-lasting parts for frequent commercial use. The inconsistent quality makes it a gamble. It’s a budget option for homeowners who don’t mind replacing spools often and are comfortable troubleshooting fit issues. For the same price, consider OEM Stihl or a higher-rated aftermarket brand.
