This front ONE-WAY axle pulley is an RC-scale replacement part intended for XRAY RX8 belt chassis setups. Machined features and material choice focus on service life and predictable behaviour in model drivetrain assemblies rather than cosmetic change.
Manufactured from 7075 aluminium and given a hardcoat finish, the pulley balances low mass with wear resistance appropriate for frequent track use. Side holes in the pulley body provide a route for friction debris to exit the contact area, helping to keep belt and axle interfaces cleaner during running.
In practical terms the part fits into the RX8 front one-way arrangement, where it functions as a rotating interface within the chassis belt path. When installing, verify alignment with the belt line and check for free rotation under load; final tuning should focus on belt tension and mesh rather than modifying the pulley itself.
