ERGIT 3-Pack Spool Replacement for Stihl Autocut C3-2 Trimmer Head Fits FSA 57

What It Is

This is a 3-pack of pre-wound replacement spools for Stihl’s Autocut C3-2 trimmer head, designed for electric trimmers like the FSA 57. Each spool holds 0.095-inch (2.4mm) diameter trimmer line, pre-wound for drop-in installation.

Fitment & Compatibility

• Exact fit: Stihl Autocut C3-2 heads only (not the C3-1 or C-4).
• Confirmed models: Stihl FSA 57, FSA 65, FSA 90, FSA 130, FSA 135, and FSA 200. Also fits some KombiSystem units with the C3-2 head (e.g., KM 56, KM 90, KM 94).
• OEM equivalent: Replaces Stihl part # 4000 713 9007 (original 2-pack). ERGIT is a third-party aftermarket brand.
• Check before buying: Look at your trimmer head – it must say “Autocut C3-2” on the side. If your trimmer uses a different head (SpeedFeed, Tap & Go, etc.), this spool will not fit. Measure your current line diameter; this spool uses 0.095" line – if your OEM spool uses 0.080" or 0.100", it may not feed correctly.

Key Things to Know

• Line quality: The included line is slightly stiffer than Stihl OEM. It cuts well in grass but may wear faster on gravel or pavement edges. Expect shorter life than genuine Stihl spools.
• Installation ease: Drop-in replacement – no winding required. Push the spool into the head, thread the line through the eyelets, and snap the cover on. Takes under 2 minutes.
• Common gotcha: The spool hubs are slightly smaller than OEM. In some heads, the spool may wobble or jam if the head is worn. If your C3-2 head has >2 seasons of use, consider replacing the head too.
• Value note: At $18.99 for 3 spools, it’s roughly half the cost of the official Stihl 2-pack. You lose some durability but save money per spool.

Should You Buy It

Buy this if you have a Stihl electric trimmer with the Autocut C3-2 head, you go through line quickly, and you’re okay with slightly shorter line life to save about 40% per spool. Skip it if you need maximum durability for heavy-duty commercial use, or if your trimmer head is old and worn – in that case, buy the OEM spools or replace the head.
