Upgrade your Stihl strimmer with the STIHL Autocut Trimmer Head Replacement Set – a reliable, premium‑quality solution that keeps your cutting line feeding smoothly every time.
Designed for the popular C5‑2 self‑feed system, each set includes three identical heads (equivalent to part numbers 4006 / 710 / 2106) pre‑wound with high‑performance line. The M8 × 1.25 LHF thread ensures a secure fit on the following models:
- FS38
- FS45
- FS46
- FSE60
- FS50
Key benefits
- Ready‑to‑use: Each head arrives with a pre‑wound spool, so you can swap it in seconds—no extra line winding required.
- Durable construction: Engineered from robust polymer and metal components to resist wear and maintain consistent line feed.
- Universal fit: Fully compatible with Stihl’s C5‑2 system across multiple model lines, making it a versatile spare or upgrade.
- Cost‑effective: Pack of three provides extra heads for backup or larger projects, reducing downtime.
Installation is straightforward: remove the old head, attach the new one using the M8 × 1.25 thread, and tighten securely. Once in place, the self‑feed mechanism automatically releases line as you trim, delivering clean cuts on grass, weeds, and light brush.
Note: This is a high‑quality aftermarket replacement and not an original Stihl part.
