UPFOREST 16" Chainsaw Bar and 3 S55 Chains for Stihl MS170 MS180 — .050" Gauge, 3/8" LP, Tail Mount A074

Replace worn components quickly with this matched bar-and-chain kit engineered for small gas and electric chainsaws up to 42 cc. The combo includes a 16" guide bar (tail mount A074, 7-tooth sprocket nose) and three .050" gauge, 3/8" low-profile (LP) S55 semi-chisel chains designed to meet ANSI B175.1-2018 low-kickback performance. Materials and heat treatment focus on durability and consistent tension so you spend less time maintaining equipment and more time cutting wood.

How does the 16" guide bar improve handling and safety?

The 16-inch guide bar is sized to reduce kickback compared with longer bars while maintaining good reach for common yard and property work. It's lightweight for easier control and better maneuverability, especially for occasional users and those with smaller saws.

• Tail mount A074 fits popular small Stihl models.
• Sprocket nose with 7 teeth reduces friction and smooths chain travel.
• Shorter bar length lowers tip reaction and increases operator control.
• Balanced for low fatigue during extended cutting tasks.

What makes the S55 chains durable and keep a sharp edge?

These chains are produced from German-grade steel with controlled heating and a precise punching process to improve toughness and flatness. Rivets are hardened and quenched to resist wear, and cutters receive chrome plating plus rotary grinding for a longer-lasting, sharper profile.

• Heat-treated rivets minimize tension variation over time.
• Chrome-plated cutters reduce abrasion and slow dulling.
• Rotary machine grinding ensures consistent cutter geometry.
• Semi-chisel teeth balance cutting speed and easier maintenance.

Which Stihl models and specifications does this kit fit?

This bar-and-chain set is sized for chainsaws with engine displacement up to 42 cc and fits many Stihl saws such as the MS 170, MS 180, and MS 180 C. Check your saw's tail mount code, sprocket tooth count, and required chain pitch/gauge to confirm compatibility.

• Compatible chain: 16" length, .050" gauge, 3/8" LP pitch, S55, 55 drive links.
• Bar tail mount: A074; sprocket nose teeth: 7.
• Common compatible models: Stihl MS170, MS180, MS180 C (verify on your saw).
• Contact UPFOREST with your bar/chainsaw specs if unsure.

How will this combo affect maintenance and performance?

The matched set aims to reduce routine adjustments by holding tension and resisting wear, so you get steadier performance between tune-ups. Using properly hardened rivets and plated cutters helps the chain stay sharper longer, decreasing filing frequency and improving cutting consistency.

• Hardened rivets reduce elongation and keep tension stable.
• Plated cutters resist corrosion and abrasion for longer intervals between sharpening.
• Sprocket nose minimizes chain drag and extends bar life.
• Three spare chains allow fast replacements to keep your saw running.

Who is this for: This UPFOREST 16" bar and 3-chain kit is tailored for homeowners, land managers, and occasional lumber workers who use compact chainsaws (up to 42 cc) like the Stihl MS170/MS180. It suits anyone who wants a ready-to-install OEM-style replacement that prioritizes control, wear resistance, and predictable maintenance intervals without specialist tools.
