Richard ★★★★★ Oct 21, 2026

The hardened steel feels noticeably more durable than the standard pinion gears I've used before, and the 1/8" bore was a perfect fit on my motor shaft. After a few runs, there's zero wear visible, so it seems like it'll hold up for a long time.

Grace D. ★★★★★ Oct 20, 2026

Got these for my 48-pitch build and the hardened steel feels noticeably tougher than the standard ones I've used before—the 1/8" bore fit my motor shaft perfectly no issues there.

Madison T. ★★★★★ Oct 18, 2026

Installed the 18-tooth version on my 1/8" motor shaft and it slid on perfectly tight, no slop. These teeth are machined clean, meshing with my spur gear quieter than the plastic one I used before. Definite upgrade for the money.
