Gb Protop Titanium Chainsaw Bar for .404 Pitch, .063 Gauge, HV D009 Profile

Description

GB ProTop “Titanium” Chainsaw Bar — Husqvarna Large Mount (HV / D009), .404″ × .063″

Built for demanding professional users. ProTop “Titanium” bars pair a solid, heat-treated alloy-steel body with a replaceable sprocket-nose tip for smooth feed, stable tracking and long service life on high-power saws.

Key Benefits

• Low-friction cutting: Sprocket-nose tip reduces drag versus hard-nose bars.
• Durable rails: Heat-treated solid body resists groove and tip wear.
• Balanced handling: Confident control for bucking, felling and milling.
• Lower lifetime cost: Replace the nose assembly instead of the whole bar.

Fitment Checklist (Reduce Returns)

• Confirm your bar mount is HV / D009 (Husqvarna large-mount).
• Confirm your setup is .404″ pitch and .063″ gauge.
• Requires a .404″ drive rim/sprocket. Not compatible with 3/8″ sprockets or chain.

Important: Bar pitch must match the saw’s drive sprocket pitch. Mixing .404″ with 3/8″ can cause damage and void warranty.

.404″ Drive-Link & Weight Reference

Drive-link counts are sourced from GB Forestry Australia and assume a standard 7-tooth rim sprocket. Required DL may vary with sprocket size (rim or spur), saw model, bar wear and chain type. Always confirm against your existing chain.
