This Delrin drive gear is built for HPI Savage, Savage X and Savage Fluorescent models and spans the 18-23T tooth counts shown in the title. It is a replacement part intended to reduce drivetrain noise and provide consistent engagement compared with some harder molding compounds.
Choose this gear when performing routine drivetrain service or when swapping ratios within the 18-23T window. The Delrin construction tends to run quieter and can change the engagement feel, so verify the contact pattern and watch for early wear signs after fitting.
Installation guidance: designed as a drop-in option for compatible Savage platforms; confirm tooth count and mounting fit before installing, then test and recheck mesh and fasteners after initial use.
