Overview
The Powerhobby Helical Spiral Pinion Gear Set is a precision drivetrain upgrade for Axial SCX10 II, SCX10 III, and Capra 1.9 UTB rock crawlers. Featuring a helical-cut 8-tooth pinion paired with a 33-tooth spur gear, this set provides smoother, quieter, and more efficient power transfer than the stock straight-cut gearing.
Helical gears mesh more progressively than straight-cut gears, which significantly reduces drivetrain noise and shock loads — perfect for crawling enthusiasts who want a refined, scale-quiet driving experience without giving up durability.
