XRAY RX8 Touring Front Pulley 18T - Arrowmax AM-RX8-345858  [AM-RX8-345858]

RX8 front pulley replacement

The Arrowmax AM-RX8-345858 front belt pulley is produced as an aftermarket replacement for the XRAY RX8 belt-driven drivetrain. Machined from 7075 T6 aluminium and given a hard-coated surface, the pulley balances lightness and improved wear resistance for club runs and practice sessions.

Key engineering points concentrate on drivetrain consistency and debris management: precision CNC machining for concentricity, a durable hard-coated finish, and side vent holes to help eject grit from the groove. These features support consistent belt tracking and help reduce premature wear on the front pulley.

Usage and tuning advice: designed for the front belt location on RX8 chassis belt systems, pulley accuracy and profile affect belt tension and drivetrain smoothness. Verify pulley alignment and adjust belt tension to the recommended values when replacing the part; consider this unit a reliable spare or upgraded replacement rather than a performance overhaul.
