The Vortex 347ZK-55 is a 55-tooth steel rear sprocket engineered for serious street and track riders who demand precise power delivery and long-lasting durability. Built to Vortex's exacting standards, this sprocket is manufactured from carbon steel alloy with an electro-plated satin black finish to resist corrosion and maintain appearance over time.

Key Features:

• 55-Tooth Steel Construction – Carbon steel alloy provides exceptional strength and longevity under hard acceleration and repeated load cycles
• Black Corrosion-Resistant Finish – Electro-plated satin black coating protects against rust and environmental wear
• Patented Tooth Design – Vortex's unique tooth profile reduces chain wear and extends overall drivetrain life
• CNC Manufactured in the USA – Precision machined to tight tolerances for consistent concentricity and smooth chain engagement
