All Metal Dual Gear Upgrade Kit For Direct Drive 3D Printer Extruders With Nano Coated Hardened Steel Helical Gears And One Piece Shaft For Beefed Up Filament Drive And Smooth Consistent Feeding

2-Pack All-Metal Dual Gear Upgrade Kit for Extruders
✔️ Nano-coated hardened steel gears for smoother filament feed

This all-metal upgrade kit enhances direct-drive extruders by replacing standard gears with nano-coated hardened steel helical gears and a one-piece shaft. It’s designed to boost filament control and feeding consistency on 3D printers like Neptune 4/Pro/Plus/Max. No firmware changes required, just a straightforward swap.

✅ All-metal drive gears with nano-coated surface resist corrosion and wear
✅ One-piece shaft design offers better gear concentricity and stable feeding
✅ CNC hollow POM gears reduce weight while maintaining strength
✅ Gear reduction increases extrusion torque for consistent filament delivery
✅ DLC-coated dual-gear set with double-ball bearings for higher precision and longer life
