2-Set 25-2 Trimmer Head Rebuild Kit,Parts Head Spool and Cover Cap Fit for Stihl 25-2 FS44 FS55 FS80 FS83 FS85 FS90 FS100 FS100RX FS110 FS120 FS130 FS200 FS250 String Trimmer

What It Is

This is a 2-set trimmer head rebuild kit that replaces the spool and cover cap on Stihl 25-2 trimmer heads. It’s designed for homeowners and light commercial users needing to refresh worn-out line feeding components without buying a whole new head.

Fitment & Compatibility

Check your model number: Fits Stihl FS44, FS55, FS80, FS83, FS85, FS90, FS100, FS100RX, FS110, FS120, FS130, FS200, FS250 string trimmers—but only if they use the 25-2 head. Not all FS-series trimmers shipped with this head; some came with AutoCut or other heads. Verify your existing head has “25-2” molded on the cover or spool.
Measurements: The spool diameter is roughly 2.5 inches; cover cap inner diameter is 1.5 inches. If your current head is larger or has a different line loading pattern, this kit won’t match.
OEM vs aftermarket: This is a generic replacement, not Stihl OEM. Expect slightly looser tolerances than genuine parts—common with budget rebuilds.

Key Things to Know

• Quality: The plastic is functional but less durable than OEM Stihl parts. It may crack if over-tightened or used on heavy brush.
• Installation difficulty: Easy—10 minutes. Remove the old spool and cap, snap in the new spool, wind line, and press the cap on. No tools needed.
• Common gotchas: The cap may pop off under high RPM if not fully seated. Ensure it clicks firmly. Also, the line exit holes can be sharp—deburr with a file if line frays.
• Includes: Two complete sets (spool + cap). Good for backup or dual-tool owners.

Should You Buy It

Buy this if you have a confirmed 25-2 head on a compatible Stihl trimmer and want a cheap, quick fix for worn line feeding. Skip it if you need long-term durability for commercial use or want OEM fit—spend more on genuine Stihl parts.
