This 53-tooth spur gear is supplied as part number JR-CHP-SAV-039 and fits HPI Savage Nitro Off Road Series vehicles as the main spur in the drivetrain. Manufactured from POM with a black finish, it meshes with the pinion gear to transfer motor torque into the gearbox and onto the wheels.
Service guidance: inspect teeth for wear or damage, ensure the pinion mesh is correct, and keep the gearbox free from debris prior to installation. The item is delivered as a single replacement spur for applicable Savage models.
When changing gearing or motor components, recheck mesh clearance to prevent premature wear. This item is intended for RC model applications only.
Use JR-CHP-SAV-039 to replace worn main spur gears on Savage Nitro Off Road models and maintain regular mesh and drivetrain inspections for reliable operation.
