This Arrowmax AM-RX8-345888 front side belt pulley is designed as a direct replacement part for XRAY RX8 series maintenance and setup. The pulley is CNC machined from 7075 T6 aluminium and receives a hard coating; the construction and finish are intended to resist wear from belt contact while keeping weight low for drivetrain responsiveness.
The side profile includes drilled holes that help clear debris and reduce trapped material at the friction interface, which can simplify cleaning during routine service. As a front pulley, it plays a role in belt tension distribution and can be used when swapping or refreshing front drivetrain components on RX8 layouts.
Installation notes: treat this as an RC-scale spare for the RX8 chassis, fit it in place of the original front side pulley using the factory hardware, check belt alignment and tension after fitting, and inspect for proper seating before the first run.
