Traxxas Middle 4.5mm Width 121-Groove HTD RC Drive Belt - 4863

The Traxxas 4863 is a middle drive belt designed as a direct-fit spare for Traxxas belt-driven RC models. Carrying the style code TRX4863, this HTD-profile belt measures 4.5mm in width with a 121-groove tooth count, making it a specific and precise component for maintaining the drivetrain on compatible Traxxas vehicles. If your existing belt has snapped, stretched, or worn through, replacing it with the correct OEM-spec part keeps the drivetrain running as intended without requiring modifications.
