Vortex 404ZK-46 CAT5 Black 46-Tooth 520-Pitch Rear Sprocket

The Vortex 404ZK-46 is a CAT5 aluminum rear sprocket featuring a 46-tooth count on a 520 pitch, finished in a durable black hard-coat anodizing. Engineered by Vortex Racing for street and track use, this sprocket delivers the ideal balance of lightweight performance and long-lasting durability.

Key Features:

• 46 Teeth / 520 Pitch — direct-fit replacement or performance gearing upgrade
• Black Hard-Coat Anodized Finish — corrosion-resistant and scratch-resistant for lasting good looks
• Lightweight CAT5 Aluminum Construction — reduces rotating mass for improved throttle response and acceleration
• 100% CNC Machined in the USA — precision-manufactured to tight tolerances
• Specially Formulated Alloy — proprietary Vortex alloy blend for optimal strength-to-weight ratio
• Patented Tooth Design — unique Vortex tooth profile increases sprocket longevity and improves chain engagement

The Vortex 404ZK-46 rear sprocket is a popular choice for riders looking to fine-tune their final drive gearing. Moving to a higher tooth count rear sprocket increases low-end torque and acceleration at the expense of top-end speed. This sprocket pairs with a standard 520-pitch drive chain.
