The XRAY 305582 One-way Pulley with Grooved One-way Bearing is a compact replacement built for hobbyists working on older T Series RC cars. It is designed to improve drivetrain smoothness and give more predictable power delivery out on the track.
This one-way pulley is made to match the geometry of older T Series versions, allowing direct swap-in with existing components. The grooved one-way bearing helps prevent slippage and improves torque transfer, so the drive feels more consistent during acceleration and corner exits.
Installation is straightforward and intended for hobbyists who want to preserve original specs while boosting reliability. The pulley installs into compatible XRAY drivetrain layouts without complex modification.
