Vortex 463ZBV4-42 V4 Aluminum Rear Sprocket Black 42-Tooth

The Vortex 463ZBV4-42 is a 42-tooth V4 series aluminum rear sprocket finished in black anodize with contrast-machined accents. As the latest evolution of Vortex Racing's renowned aluminum sprocket platform, the V4 design delivers a 10–15% weight reduction over the previous CAT5 generation while maintaining full strength through an optimized material distribution pattern and machined faces on both sides.

Key Features:

• V4 Series Design: Next-generation sprocket architecture with improved strength-to-weight ratio and enhanced consistency across the product range
• 100% CNC Manufactured in the USA to the tightest tolerances for precise chain engagement and fit
• Specially formulated aerospace-grade aluminum alloy per Vortex specifications for optimal performance
• Black anodized finish applied before CNC machining, producing the iconic two-tone look with silver machined highlights
• Unique Vortex tooth design increases sprocket longevity and maximizes power transfer efficiency
• 42 teeth — ideal for tuning gear ratios toward improved low-end torque and acceleration
• Reduces rotating mass compared to OEM steel sprockets for improved throttle response and handling

Vortex aluminum sprockets are the choice of professional road racing, track day, and high-performance street riders worldwide. For maximum sprocket and chain life, clean and tension the chain every 300–600 miles on street applications. The 463ZBV4-42 must be paired with a matching-pitch chain and front sprocket.
