This Delrin drive gear suits HPI Savage, Savage X and Savage Fluorescent machines across the 18-23T range listed in the product title. It is supplied as an aftermarket replacement aimed at reducing drivetrain noise while maintaining reliable tooth engagement.
Use the gear as a direct replacement during maintenance or when adjusting gear ratios that fall inside the 18-23T span. The material choice helps lower gear whine and smooth engagement, but check mesh alignment and mating gear condition after installation.
Fit notes: intended for drop-in replacement on compatible Savage variants without chassis modification; verify tooth count and orientation, then re-inspect gear mesh and securing hardware on first test runs.
