Wired this into my X3 and the speed control is now buttery smooth across the full range—no more sudden jumps. The shaft feels solid and the detents click nicely at each stop.

The fit on the X3 mill is perfect—no filing needed to seat it in the housing. Turned the speed dial down to a crawl for a slow pass and the response was smooth with zero dead spots at the low end.

Installed it on the X3 mill as the standard SKU 3376 replacement, and the knob turns smoothly with no dead zone in the low-speed range. It’s a direct fit, so I didn’t have to modify anything to get it working.
