Vortex CKG6330 GFRA Gold 520 Chain and Sprocket Kit 15/43T

The Vortex CKG6330 is a complete GFRA "GoFast" 520 conversion chain and sprocket kit designed for performance street riding. This kit pairs a hardcoat aluminum rear sprocket with a high-performance Vortex RX3 gold chain, delivering a ready-to-install drivetrain upgrade in a 15/43 tooth front/rear configuration.

Key Features:

• 520 Conversion Kit — Lighter 520-pitch chain reduces rotating mass for improved acceleration
• Vortex RX3 Gold Chain — Made in Japan to exacting quality standards; features a dual pocket sealing system for extended wear life
• F5 PTFE Black Hardcoat Aluminum Rear Sprocket — Hard anodized with a jet black dye and coated in PTFE for added lubricity, resulting in a cleaner, longer-lasting sprocket
• 7075-T6 Aluminum Construction — Premium aerospace-grade aluminum provides the optimal balance of lightweight performance and durability
• 15/43 Tooth Gearing — One tooth down in front with stock-equivalent rear gearing for optimized street performance
• Ready to Install — Complete kit requires no chain cutting

Switching to a lightweight aluminum sprocket from a heavy steel OEM unit multiplies weight savings across the entire rotating drivetrain assembly. Reduced rotating mass translates directly to sharper throttle response and improved acceleration. The Vortex RX3 chain and PTFE-coated sprocket combination also stays cleaner and resists wear longer than standard components, making the CKG6330 a smart long-term performance investment.
