Vortex CKG6351 HFRA 520 Conversion Chain and Sprocket Kit 14-42 Tooth Gold

The Vortex CKG6351 is an HFRA (Hyper Fast) 520 conversion street performance kit featuring a hardcoat aluminum rear sprocket with modified gearing—one tooth down in front and two teeth up in the rear—paired with a gold SX3 Vortex chain. This complete kit includes a 14-tooth front sprocket, 42-tooth rear sprocket, and a 108-link gold 520 chain with 8,500 lbs tensile strength.

Key Features:

• F5 PTFE Black Hardcoat rear sprocket built for endurance—hard anodized with jet black dye, then coated with PTFE for added lubricity, resulting in an ultra-tough, ultra-light sprocket that stays cleaner and lasts longer
• Constructed from 7075-T6 aluminum, the best grade material for lightweight performance and durability
• High-performance x-ring chain and precisely manufactured sprockets designed specifically for racing and high-speed applications, offering enhanced durability, efficiency, and performance
• Reduced rotating mass improves acceleration—weight savings on drive components are multiplied as rotating mass
• Ready to install with no chain cutting required
• Includes rivet-type master link

Vortex chain and sprocket kits are chosen by riders for their superior craftsmanship, longevity, and the ability to fine-tune gear ratios for improved acceleration and top-end speed. This HFRA configuration is ideal for riders seeking aggressive acceleration and enhanced low-end to mid-range performance.
