Upgrade the Xray RX8 Drivetrain with Arrowmax 18T Pulley

The Arrowmax AM-RX8-345838 composite side belt pulley is a precision upgrade made for the Xray RX8 line, combining durability and controlled weight. Built from 7075 T6 aluminum, this 18-tooth rear pulley balances robust construction with race-ready lightness for consistent lap times.

CNC Precision for Reliable Fit

CNC machining ensures tight tolerances and smooth engagement with your belt system, while the hard surface finish improves wear resistance. The result is dependable operation that helps cut down on frequent rebuilds.

Holes That Keep Your Drivetrain Cleaner

Purpose-drilled openings on the pulley help shed dirt and grit to reduce abrasion and prolong component life, which is useful when running on mixed surfaces and in club-level racing.

Will this pulley fit other Xray variants?

This pulley is model-matched to the Xray RX8 family and is optimised for that platform. Other Xray kits may require spacers or different mounting parts to use it.

What are the advantages of 7075 aluminium here?

7075 aluminium gives a high strength-to-weight ratio and resists deformation under load, so the pulley keeps its shape and mesh under race conditions while staying light.

Any installation tips for best performance?

Ensure clean belt contact and correct alignment when fitting the pulley, check belt tension after initial runs, and inspect for debris around the holes to maintain smooth operation.
