Vortex CKG6435 GFRA GoFast Conversion Chain and Sprocket Kit - 520 Gold

The Vortex CKG6435 is a GFRA "GoFast" 520 Conversion Street Chain and Sprocket Kit finished in gold. This kit is engineered for riders looking to improve throttle response and acceleration through a 520 chain pitch conversion, pairing a gearing-one-down front sprocket with a stock-equivalent rear sprocket for quicker off-the-line performance.

What's Included:

• 1 × High-carbon steel front sprocket — nickel plated to resist corrosion, induction hardened to reduce surface wear, with drilled lightening holes to reduce rotating mass
• 1 × F5 PTFE Black Hardcoat aluminum rear sprocket (7075-T6 aerospace-grade aluminum, hard anodized and PTFE coated for added lubricity and longevity)
• 1 × Vortex G520SX3 Gold 120-link chain with rivet-type master link

Front Sprocket Features:

• High carbon steel construction for maximum strength
• Special Vortex nickel plating for corrosion resistance
• Induction hardened to minimize surface wear
• Precision tolerances to ensure concentricity
• Drilled holes reduce rotating mass

Rear Sprocket Features:

• 7075-T6 aerospace-grade aluminum — lightweight and durable
• F5 PTFE Black Hardcoat finish: hard anodized and PTFE coated for a cleaner, longer-lasting sprocket
• Significantly reduces unsprung and rotating mass compared to OEM steel sprockets

Chain Specifications (G520SX3 Gold):

• Chain size: 520 pitch
• Links: 120
• Color: Gold
• Average tensile strength: 8,500 lbs
• SX3 tri-glide dual-pocket seal design reduces heat and friction for extended wear life over standard O-ring chains
• Includes rivet-type master link

Vortex Performance Links chains are manufactured in Japan to exacting quality standards. The SX3 series features a dual-pocket sealing system that delivers up to 7 times longer wear life compared to standard O-ring chains. Combined with the lightweight aluminum rear sprocket and hardened steel front sprocket, this complete kit is a high-value upgrade over OEM drivetrain components.

WARNING: Gold-colored chains can expose you to Nickel, which is known to the State of California to cause cancer. For more information, visit www.P65Warnings.ca.gov.
