Replacement Trimmer Head 3 Pack Replacement Spool for Stihl Fsa 56， Replacement String Heads for Stihl C2-2，Weed Eater String for Stihl Autocut 2-2 Fsa 56 4008 710 4302

What It Is

This is a 3-pack of replacement trimmer heads and pre-wound spools designed for battery-powered Stihl trimmers like the FSA 56, as well as Stihl’s Autocut 2-2 and C2-2 head systems. It’s meant for homeowners maintaining small to medium lawns with a lightweight electric string trimmer.

Fitment & Compatibility

• Exact fit models: Stihl FSA 56, FSA 65, FSA 86, and any trimmer using the Autocut 2-2 or C2-2 head (OEM part number 4008 710 4302).
• Measure before buying: Check that your trimmer’s shaft diameter matches the head’s mounting hole (typically 25.4 mm for these Stihl models). Also verify line diameter: this pack uses 0.080” (2.0 mm) line—too thin for heavy weeds, too thick for some smaller trimmers.
• Aftermarket note: This is a non-OEM replacement. It may not have the same bump-feed reliability or durability as the original Stihl part. Test fit before full installation.

Key Things to Know

• Quality concerns: With a 3.0-star rating from only 9 reviews, expect inconsistent fit or premature wear. Some users report the spool doesn’t advance smoothly.
• Installation is simple: No tools required—snap off the old head, snap on the new one, and thread the line through the eyelets. Pre-wound spools save winding time.
• Common gotcha: The line may break more easily than OEM, especially against rough surfaces or edging. Keep the speed low for the first few uses to see how it holds.
• Value vs. OEM: At $17.79 for three heads, it’s cheaper than buying a single Stihl head, but you may replace it sooner.

Should You Buy It

Only if you need a quick, budget-friendly backup for light trimming and don’t mind replacing heads more often. For heavy use or professional results, stick with the genuine Stihl Autocut 2-2 head—it’s more reliable and feeds line consistently.
