XRAY RX8 20T Two-Speed Tuning Pulley Lightweight by Arrowmax AM-RX8-345820  [AM-RX8-345820]

Two-speed pulley for RX8 tuning

This 20T 2-speed belt pulley is built for XRAY RX8 two-speed gearboxes and supplied by Arrowmax under model AM-RX8-345820. It is CNC machined from 7075 T6 aluminium then hard coated to balance reduced weight with improved surface durability for regular running. Holes on the pulley flank are positioned to help evacuate belt debris that can interfere with shift consistency.

As part of an RX8 two-speed assembly the pulley influences final drive ratios and shift behaviour. Tight machining tolerances produce accurate concentricity for steadier belt tracking and dependable engagement during high RPM use. Replace worn pulleys with this option when tuning or refreshing an RX8 transmission.
