The Serpent SER905121 rear belt is a purpose-made replacement to keep your RC car running with reliable power transfer. Precision control of the belt profile helps reduce drivetrain slop and inconsistent power.
This rear belt fits multiple Serpent models that share the same belt design. Always confirm the SER905121 part number and compare belt routing before installation to ensure a correct match.
When installing the Serpent SER905121 rear belt, set the tension to eliminate slack while avoiding excess preload. Periodic checks of alignment and wear will maximise service life.
