4Pcs 3D Printer Flat Bed Die Springs Level Upgrade Kit Ender 3 Pro V2 Cr-10 Cr-X

This is one of the best upgrades you can do to your printer.
The 25mm length is the correct spec for the spring - years ago, people used 20mm springs, but those can be too short in some cases.
Note for the Ender 3 V2: If you have trouble fitting the springs, raise the Z Stop just a touch. It may have been installed too low.
The Z Stop is the limit switch attached to the upright on the extruder side.
Each item consists of a set of 4 springs.

NOTES

Please allow a 1-3 cm difference due to manual measurements.
Please note that slight colour differences should be acceptable due to the light and screen.
