Abigail B. ★★★★★

Finally found a replacement that fits the quill pinion perfectly—the alignment holes matched up without any extra shimming. I had been fighting with a sloppy lock for months; now it’s solid and the handle assembly feels tight.

David ★★★★★

Installed this on my SIEG SX3.5 and the pinion alignment is spot on now — the quill lock finally moves smoothly without binding.

Elizabeth O. ★★★★★

Finally, a quill lock shaft that actually stays aligned during assembly. The fit on my SIEG SX3.5 was perfect—no slop at all, and it made the whole pinion adjustment process feel more solid.
