Vortex 196AZBV4-43 V4 Aluminum Rear Sprocket 43T Blue Anodized

The Vortex 196AZBV4-43 is a 43-tooth aluminum rear sprocket featuring Vortex's latest V4 design — an evolution of their legendary CAT5 platform engineered for maximum performance with reduced weight. Debuted in 2026, the V4 pattern achieves a 10–15% weight reduction over the CAT5 without sacrificing structural integrity, using machined faces on both sides for optimal strength distribution.

Key Features:

• V4 Design: New lightweight pattern with machined faces on both sides for best-in-class strength-to-weight ratio
• Blue Anodized Finish (AZB): Anodized coating applied before cutting, producing the iconic two-tone machined look
• 7075-T6 Billet Aluminum: Aerospace-grade alloy machined to precise tolerances for reduced rotating mass
• 100% CNC Manufactured in the USA: Made to the tightest tolerances using Vortex's specially formulated alloy
• Vortex Patented Sprocket Design: Unique tooth geometry increases longevity and improves chain engagement
• 43 Teeth: Ideal for fine-tuning gear ratios for improved acceleration and low-end torque

Aluminum sprockets are the preferred choice for road racing, motocross, flat track, and drag racing applications where weight savings are critical. For best results, clean the chain and sprocket every 300–600 miles on street bikes and after every ride on dirt bikes. Always ensure the chain pitch matches the sprocket pitch when replacing drivetrain components.
