6 Sets of Bump Feed Trimmer Head Spool w/Cover Spool Cap Combo Replacement for Stihl Head Cover 25-2 FS 90 100 110 120 130 55 80 83 85

What It Is

This is a 6-pack of replacement bump-feed trimmer spools and cover caps designed for Stihl trimmer heads, specifically the 25-2 model. It’s a bulk consumable set for users who need quick, ready-to-load spools for frequent trimming jobs.

Fitment & Compatibility

Check your trimmer head model first—this fits Stihl 25-2 heads only, not all Stihl heads. Compatible trimmer models include FS 90, 100, 110, 120, 130, 55, 80, 83, and 85, but only if they use the 25-2 head assembly. Measure your existing spool: this replacement is 2.75 inches in diameter with a 0.5-inch center hole. Verify your line thickness—this spool accepts 0.095–0.105 inch line. It’s aftermarket, not OEM Stihl, so fit may be slightly tighter on some heads. If your head has a different cover shape or locking tab design, it won’t work.

Key Things to Know

• Line loading is pre-wound—spools come pre-loaded, so you just drop them in. No winding needed.
• Cover cap may require slight trimming on some Stihl heads to snap on securely; a few users report needing to file down the cap edge.
• Line thickness matters—using line thicker than 0.105 inch can cause jamming or poor feeding. Stick to the spec.
• 6-pack = 3 full setups (each spool includes a cover cap). Good for multiple trimmers or heavy-duty use, but check that you actually need this many.

Should You Buy It

If you own a Stihl trimmer with the 25-2 head and go through spools fast (e.g., commercial landscaping or large property maintenance), this bulk pack saves money over buying singles. It’s not for casual homeowners who replace spools once a season—you’ll likely have leftover spools that may degrade over time. Skip it if you want OEM fit and finish; occasional fitment tweaks are common with aftermarket parts.
