Direct replacement lead screw for CR-10/ CR-10S, and CR-10S 400 (S4). May fit other 400mm tall i3 style printers.
May be used on CR-10 V2/V3 and CR-10S Pro/ Pro V2 if you move the Z coupler up on the motor shaft and the lead screw up in the coupler. We have verified that there is still enough engagement and since the lead screws do not bottom out, it allows the coupler to do its job. The difference is 10mm.
