UPFOREST 20-inch chainsaw chain for Stihl models — .325" pitch, .063" gauge, 81 links, hardened steel

UPFOREST 20-inch replacement chainsaw chain: .325" pitch, .063" gauge, 81 drive links — engineered for compatible Stihl models and built for durable, sharp cutting performance.

This replacement chain is designed to fit a wide range of Stihl guide bars (including MS290, MS291, MS271, MS261, MS270, MS280 and models using 024–039 bars) and other chainsaws that accept a 20" chain with .325" pitch and .063" gauge. Constructed from hardened German steel and finished with Japanese chrome-plating, the chain aims to balance cutting speed, wear resistance, and consistent tension. Each order includes a Swiss double-cut file sharpener and protective oil to help maintain peak performance out of the box.

Which saw models and bars will this 20" chain fit?

Confirm compatibility by matching three key measurements: pitch (.325"), gauge (.063"), and drive link count (81). This chain is commonly compatible with many Stihl models and bars listed in the product title, but always verify against your saw’s manual or the bar’s stamped numbers.

• Pitch: .325"
• Gauge: .063" (1.6 mm)
• Drive links: 81
• Fits many Stihl 024–039 series bars and similar aftermarket bars

How is the chain constructed and why does that matter?

The chain uses German steel with controlled heating and punching for improved toughness and flatter plates. Rivets are hardened and quenched to reduce wear and maintain tension, while cutters receive Japanese chrome plating and precision grinding to stay sharp longer.

• Hardened, quenched rivets for strength and stability
• Chrome-plated cutters for corrosion resistance and durability
• Precision cold-heading and grinding for consistent tooth geometry

What maintenance comes with the chain and how do I keep it cutting well?

UPFOREST includes a Swiss double-cut premium file sharpener and a small protective oil so you can sharpen and protect the chain as soon as it arrives. Regular sharpening, proper bar and chain lubrication, and correct tensioning will extend life and optimize cutting efficiency.

• Included sharpener: double-cut Swiss file for quick tooth touch-ups
• Protective oil: temporary corrosion resistance for storage and installation
• Maintenance tips: check tension after first few cuts, lubricate bar continuously

Is this chain safe and what performance can I expect?

This is a full-chisel, low-kickback design meeting ANSI B175.1-2012 kickback performance requirements when tested under those standards. Expect fast cutting on soft and medium hardwoods, with reduced kickback characteristics compared to aggressive chisel-only chains, while following safe operating practices.

• Full-chisel cutters for efficient, rapid cutting
• Low-kickback construction tested to ANSI B175.1-2012
• Best used with proper PPE and recommended chain brakes

Who is this for? This 20" UPFOREST chain is aimed at homeowners, landscapers, and professional users who need a reliable, ready-to-install replacement for Stihl-compatible 20" bars. If you want a durable chain that arrives sharpened and includes handy maintenance accessories, and you can match the pitch, gauge, and drive link count, this product suits routine tree work, firewood cutting, and property maintenance tasks.
