Dual Screw Z Axis upgrade kit show contact info

Sprite Extruder Pro Kit (4001020036)
I have (5) of each of the above, again all factory sealed. Please google/amazon search the part numbers above for more information and compatibility. I purchased these for Ender-3 v2s, but they could be used on CR-10s as well.
