UPFOREST 18" Chainsaw Bar & 3 Low-Kickback Chains .325 .063 for Stihl 025 MS250 MS251 – 7-Tooth A074, Durable/Heat-Treated

UPFOREST 18-inch guide bar paired with three 18" .063" .325" low-kickback chains (26RS 68) provides a ready-to-install bar-and-chain kit compatible with many Stihl models like 025, MS250, and MS251.

This kit bundles a durable 18" guide bar and three matched saw chains engineered for balanced cutting, reduced kickback, and longer service life. Components are built from treated steels with precision grinding and heat-treated rivets to improve wear resistance and keep tension steady. It’s designed for homeowners and occasional loggers using small gasoline or electric chainsaws up to about 42 cc, and it fits multiple Stihl tail-mount configurations (A074) with a 7-tooth sprocket nose.

How does this bar-and-chain combo improve control and safety?

The 18" guide bar and low-kickback chain profile reduce abrupt reactive forces, making cuts more predictable and easier to manage. Lighter bar construction helps when working overhead or on long cuts, reducing operator fatigue. Chains are semi-chisel low-profile links meeting current ANSI kickback performance standards for consumer saws.

• Low-kickback chain design for smoother handling
• Lightweight 18" bar for easier maneuverability
• Meets ANSI B175.1-2022 kickback performance
• Tail mount A074 and 7-tooth sprocket nose compatibility

What materials and manufacturing features extend chain life?

Cutters use chrome-plated finishing and precision grinding for sharper, longer-lasting edges that resist wear. Rivets and links are heat-treated and quenched to improve toughness and reduce stretching, so chains maintain tension and performance over more hours of use. The bar surface is made and treated for flatness and consistent oiling along the rail.

• Chrome-plated cutters for corrosion resistance and durability
• Heat-treated, hardened rivets to minimize elongation
• Precision-punched and flattened bar for consistent chain travel
• Manufacturing controls to stabilize shape and hardness

Which saw models and configurations does this kit fit?

This package is intended for chainsaws that accept a tail mount A074 bar and use a 7-tooth sprocket nose, commonly found on many Stihl home and light-pro models. It’s compatible with Stihl 025, MS250, MS251 and other models with matching bar/drive specifications. If you’re unsure about fit, compare your saw’s sprocket tooth count, tail mounting type, and chain pitch/safety specs before ordering.

• Designed for tail mount A074 and 7-tooth sprocket nose
• Chain specs: 18" length, .063" gauge, .325" pitch, LP 68 DL
• Commonly fits Stihl 025, MS250, MS251 and comparable saws
• Contact UPFOREST with your saw specs for verification

How do I install and maintain the bar and chains?

Installation follows standard chainsaw procedures: remove the side cover, align the bar tail with the mount, loop the chain over the sprocket, and set proper tension before tightening. Regular maintenance includes sharpening cutters, keeping correct tension, and using recommended bar and chain oil. Proper care preserves cutting efficiency and reduces the chance of premature wear or damage.

• Fit bar tail into A074 mount and seat chain on sprocket
• Adjust tension so chain snaps back to the bar but moves freely
• Sharpen cutters and check rivet condition periodically
• Use quality bar and chain oil for consistent lubrication

This UPFOREST 18" bar and 3-chain kit is best for homeowners, property managers, and light-duty contractors who need a reliable replacement set for common Stihl models. It’s aimed at people who value a low-kickback, durable setup for pruning, limbing, small felling, and milling of firewood. If you run a high-hour professional operation or use larger saws, consult your dealer for heavy-duty alternatives.
