The T21 center pulley, model 3RAC-3PY/21, is a simple way to enhance drivetrain reliability on many 1/10 scale RC vehicles. Built from aluminum, it offers a practical balance of toughness and reduced mass for everyday hobby use.
An aluminum pulley helps preserve drivetrain efficiency by resisting deformation and wear that can affect plastic components. The T21 design aims to extend service life and maintain consistent operation under normal running conditions.
This pulley is compatible with numerous 1/10 scale setups and is designed for easy installation. Most users can fit it with basic tools and a careful alignment check to ensure proper mesh and clearance.
