Fifchall 20" Chainsaw Bar and 3-Pack .325" Pitch .063" Gauge Chains — Fits Stihl 81-Drive Models, Hardened & Lubricated

Fifchall's 20-inch bar plus three .325" pitch, .063" gauge chains form a ready-to-install replacement kit that fits many Stihl 20" chainsaws with 81 drive links.

If your Stihl or compatible saw uses a 20-inch guide bar with .325" pitch and .063" gauge, this combo supplies one alloy guide bar and three matched cutting chains so you can swap out worn parts quickly and keep working with minimal downtime. The bundle is designed for workshop and job-site use, offering hardened chains, rivet heat treatment, and a bar with an integrated lubrication channel to reduce friction and extend service life.

Which Stihl models will accept this Fifchall 20" bar and chain set?

This kit is built to the dimensions common to many Stihl saws; compatibility depends on bar length, chain pitch, gauge and number of drive links. Cross-check your saw’s specifications — if they match .325" pitch, .063" gauge and 81 drive links for a 20" bar, it should fit.

• Compatible families: MS260, MS270, MS280, MS290, MS291, MS360 and related models.
• Includes fit notes for specific Stihl part numbers: 024, 026, 028, 029, 036 and others listed by Fifchall.
• Not compatible if your saw uses different pitch, gauge, or drive link count.

How does the bar and chain combo improve durability and cutting performance?

The guide bar is made from a high-strength alloy with a hardened nose and an efficient lubrication groove to lower wear on the chain and the bar plate. Each chain is heat-treated with hardened rivets and supplied with protective oil to resist corrosion and start life smoother.

• Alloy bar resists bending and wear under heavy use.
• Lubrication channel keeps oiling consistent along the bar.
• Heat-treated chains maintain cutting edge longer and reduce frequent sharpening.

What should I know about installation and maintenance?

Installation follows standard chainsaw procedures: align the chain on the bar, fit onto the sprocket, and set proper tension before use. Check oil feed, tension, and sprocket condition; correct initial setup and routine lubrication are key to safe, long-lasting performance.

• Verify chain direction and tension before first cut.
• Keep bar groove and oil holes clean for reliable lubrication.
• Sharpen and inspect chains regularly; replace when rivets or cutters show excess wear.

Why buy a three-chain bundle instead of a single replacement chain?

Having multiple spare chains on hand reduces downtime from dulling or damage, which is valuable for frequent cutters and professional users. The bundle lets you rotate chains, maintain cutting efficiency, and save compared with buying single chains over time.

• Three chains provide immediate spares during extended jobs.
• Cost-effective compared with purchasing chains individually.
• Pairs with a single robust guide bar for consistent tracking and reduced set-up time.

Who this is for: This Fifchall 20" bar and three-chain combo is for homeowners, arborists, landscapers and professional users who own Stihl or compatible 20-inch chainsaws built to .325" pitch and .063" gauge standards and who want a reliable spare chain supply plus a durable replacement bar. It’s especially useful if you need fast field changes, reduced downtime, and a cost-efficient repair option. Always confirm your saw’s pitch, gauge and drive link count before purchasing, and follow manufacturer safety guidance when installing and operating chainsaw components.
