Arrowmax AM-RX8-345858 Composite 18T Front Belt Pulley for XRAY RX8  [AM-RX8-345858]

Lightweight 7075 Front Pulley Optimised for Racing

For RC racers upgrading their XRAY RX8, the Arrowmax AM-RX8-345858 Composite Front Belt Pulley 18T is a practical performance upgrade. CNC machined from 7075 T6 aluminum, it balances strength with low mass and features a hard-coated surface to resist wear in demanding track conditions.

Holes Designed to Cut Weight and Shed Debris

The side hole pattern reduces rotating mass while helping loose dirt and grit escape instead of building up on the pulley face. This keeps drivetrain efficiency higher and lowers routine cleaning time between runs.

Direct Fit for XRAY RX8 Drivetrains

This pulley is made to match the XRAY RX8 series mounting and geometry, making it a straightforward swap for hobbyists wanting a durable, lightweight front pulley for club racing and practice sessions.
