齒條，變速桿

After dealing with a wobble in the X3’s shifter for months, this replacement rack slid right into the fork slot and took all the play out of the mechanism. The machined teeth engage smoothly with the pinion, making gear changes feel crisp again.

The mounting holes lined up perfectly with the shifter fork assembly on my X3 mill, no filing needed. It's a solid, precise fit that feels much sturdier than the original part. Saves me from having to adjust the fork position again.

Installed this to fix the shifter fork on our X3 mill and it lined up perfectly with the existing mounts. The machining is precise and it took less than fifteen minutes to swap out the old part.
