Trimmer Head Base Cover Replacement Compatible with Stihl FSA 57 FSA57 FSE 52 FSE52, Autocut C3-2 Spool Cover Parts 4009 710 4304，String Trimmer Head Accessories White 2-Pack

What It Is

This is a replacement base cover (spool cover) for Stihl Autocut C3-2 trimmer heads, designed to hold the trimmer line spool in place and protect internal components. It fits the FSA 57, FSA 57, FSE 52, and FSE 52 battery/electric trimmers.

Fitment & Compatibility

Before buying, verify your trimmer head is the Stihl Autocut C3-2 (not C3-1 or C3-3). The cover is for the FSA 57 and FSE 52 models only—it won’t fit the FSA 60, FSA 65, or FSE 60. Check your OEM part number: 4009 710 4304 should match. This is an aftermarket part, so expect slight differences in plastic thickness or color compared to Stihl’s original. Measure your cover diameter (approx. 3.5 inches) to confirm compatibility with your head.

Key Things to Know

• Quality: The white plastic is thinner than OEM Stihl covers—handle carefully during installation to avoid cracking the tabs.
• Installation: Push the cover onto the spool until it snaps into place. No tools needed, but ensure the line feeds through the exit holes correctly.
• Common Gotcha: The cover may fit loosely on older, worn heads. If your head has damage, this alone won’t fix wobble—replace the whole head.
• Pack Includes: Two covers per pack, so you have a spare if one breaks.

Should You Buy It

If you need a cheap, functional replacement for a lost or cracked Autocut C3-2 cover on your FSA 57 or FSE 52, this works. It’s not as durable as OEM, but for under $10, it’s fine for light-duty trimming. Skip it if you want a perfect fit or have a different trimmer model.
