Vortex CK6393 SSA Chain and Sprocket Kit - 520 15-46T Black

The Vortex CK6393 is a Super Street Aluminum (SSA) 520 Chain and Sprocket Kit featuring a 15-tooth front sprocket and 46-tooth rear sprocket. This kit delivers stock gearing with the performance advantage of a hardcoat aluminum rear sprocket, making it an ideal upgrade over heavy OEM drivetrain components.

The kit includes a high-performance SX3 Vortex chain manufactured to precise tolerances, a high carbon steel front sprocket, and a 7075-T6 aluminum rear sprocket with Vortex's F5 PTFE Black Hardcoat finish. The result is a complete, bolt-on drivetrain replacement that reduces rotating mass and improves throttle response.

Key Features:

• Chain Series: SX3 520-114 link — drilled links to reduce rotating mass
• Front Sprocket: High carbon steel with drilled lightening holes, special nickel plating for corrosion resistance, and induction hardening to reduce surface wear
• Rear Sprocket: 7075-T6 aerospace-grade aluminum with F5 PTFE Black Hardcoat finish for added lubricity, durability, and a cleaner-running surface
• Gearing: 15T front / 46T rear — stock ratio
• Chain Size: 520
• Finish: Black
• Kit Series: SSA — Super Street with Aluminum rear sprocket
• Ready to install — no chain cutting required
