UPFOREST 20-inch Chainsaw Chain 3-Pack L81 — Low-kickback .325" Pitch, Chrome-Plated Cutters

UPFOREST 20" L81 chainsaw chain 3-pack is a replacement low-kickback .325" pitch, .063" gauge chain with 81 drive links designed to fit many Stihl MS-series and similar saws.

This three-pack of UPFOREST chains gives you ready-to-install spare chains machined from heat-treated German steel and chrome-plated cutters for extended edge life. Each chain is manufactured with hardened rivets and precise punch-and-grind processes to deliver consistent tension, reduced wear, and reliable cutting performance. The set ships treated with protective oil to help prevent corrosion while stored and during first use.

Which saws and bar lengths does this L81 chain fit?

The UPFOREST L81 chain is built to a .325" pitch, .063" gauge and includes 81 drive links, matching many 20-inch bar setups. It is compatible with a wide range of Stihl models and other saws that accept those specifications.

• Compatible pitch/gauge/links: .325" pitch, .063" gauge, 81 drive links.
• Fits many Stihl MS models such as MS260, MS270, MS271, MS280, MS290 and similar series.
• Designed for a 20-inch bar length but may be suitable for other bar lengths with the same link count—always verify your saw’s requirements.

How does the chain’s construction affect durability and cutting consistency?

UPFOREST uses heat-controlled processing and hardened rivets to improve strength, minimize elongation, and keep the chain flatter during operation. Japanese chrome plating on the cutters and precision grinding help the teeth retain sharpness and resist abrasion, which extends service intervals when used with correct tension and lubrication.

• Heat-treated German steel body for toughness and reduced deformation.
• Hardened, quenched rivets reduce wear at joint points and stabilize tension.
• Chrome-plated, machine-ground cutters for longer edge life and cleaner cuts.

What should I know about installation, maintenance, and safety?

Install these chains following your chainsaw manufacturer’s instructions to ensure proper tension, drive sprocket alignment, and chain brake engagement. Keep chains lubricated, sharpen as needed, and inspect rivets and cutters before each use. Low-kickback design reduces risk but does not eliminate kickback—use safe cutting techniques and protective equipment.

• Check that pitch, gauge, and drive-link count match your saw before fitting.
• Adjust chain tension correctly every time to prevent derailment and excess wear.
• Use approved bar oil and replace chains when cutters or rivets show significant wear.

Who is this for: The UPFOREST 20" L81 three-pack suits homeowners, contractors, and landscapers who need spare chains for routine work, storm cleanup, or commercial cutting. It’s especially useful for those running Stihl MS-series saws or any model requiring .325"/.063"/81 specifications and who want durable, pre-oiled replacement chains that balance cutting performance with low-kickback safety features.
