20" Archer Timber Max™ Guide Bar - .325" x .063" (81 DL) - Large Mount

The 20" Archer Timber Max™ Guide Bar (20B3-LS-SN) is a professional-grade solid steel guide bar designed for high-performance Stihl saws. Engineered for the Stihl Large Mount (D025), this 20-inch bar provides the stability and reach necessary for large-diameter timber. The Timber Max series is built with a solid-body construction that excels in demanding commercial environments, offering superior resistance to rail spread and bending.

Solid Steel Commercial Construction

Unlike standard laminated bars, the Archer Timber Max is machined from high-strength solid alloy steel to prevent flexing and ensure absolute precision during heavy cuts. The D025 tail mount ensures high-volume oil delivery to the bar rails, which is essential when running a 20-inch configuration in dense hardwoods to prevent heat discoloration and premature wear.

⚠️ Important Compatibility Note:
This bar is designed for .325" pitch drive systems only. While many large-mount Stihl saws come standard with 3/8" pitch, this bar is specifically for those running the high-performance .325" system. Ensure your drive sprocket and chain (81 DL) match this pitch exactly before operation.
