All Metal Hardened Steel DLC Coated K1 Gear Drive Set For Creality K1/ K1C/K1 Max Extruder (2 Gears)
$11.00
Upgrade or replace your stock Creality K1-series extruder gears with this all-metal hardened steel DLC-coated drive gear set. Machined from tool steel and heat-treated for high hardness, these gears are built to deliver stronger grip on filament, smoother feeding, and substantially longer wear life than the factory gears. The Diamond-Like Carbon (DLC) surface treatment adds an ultra-hard, low-friction layer that helps reduce filament dust buildup and maintains consistent extrusion over long print hours. This kit includes two matching drive gears and precision shoulder screws for direct installation into the Creality K1, K1C and K1 Max extruder.
