For YZ-834B Dog Fighter owners looking to toughen their drive train, the Yokomo ZB-PG3217 steel pinion offers a precise 32-pitch, 17-tooth solution. Its construction focuses on steady mesh and less frequent part changes under competitive or club use.
Steel pinions are favoured where longevity counts, resisting wear that can alter mesh over time. The ZB-PG3217 keeps the motor and spur engaged reliably so you maintain consistent lap times and fewer mechanical issues.
The ZB-PG3217 is produced to align with YZ-834B shaft and mount dimensions, allowing simple installation and predictable behaviour after fitting. This makes it a straightforward upgrade for maintenance or performance-minded builds.
