XRAY RX8 Front Belt Pulley 18T Precision by Arrowmax AM-RX8-345858  [AM-RX8-345858]

RX8 front belt pulley

The Arrowmax AM-RX8-345858 front belt pulley is supplied as an RC-scale replacement for the XRAY RX8 belt-driven drivetrain. Crafted from 7075 T6 aluminium with a hard-coated finish, the pulley aims to offer a low moment of inertia while resisting surface wear during routine track use.

Engineering focus covers drivetrain consistency and dirt control: precision CNC work to ensure concentricity, a hard-coated contact area to improve longevity, and side apertures that assist in clearing debris from the belt groove. These refinements help preserve steady belt tracking and reduce the risk of accelerated wear at the front pulley position.

Installation and tuning guidance: intended for the front belt position on RX8 chassis belt systems where pulley concentricity and shape influence belt tension and drivetrain smoothness. When replacing the pulley, inspect alignment and set belt tension per the recommended settings to maintain neutral handling; view this part as a direct replacement or dependable spare rather than a primary power upgrade.
