Vortex 436ZK-47 CAT5 Rear Aluminum Sprocket 530 Pitch 47-Tooth Black

The Vortex 436ZK-47 is a 47-tooth, 530-pitch CAT5 rear aluminum sprocket finished in black anodize with contrasting silver machine cuts. Engineered for performance street and track riders who demand lightweight drivetrain components without sacrificing durability, this sprocket reduces rotating mass compared to OEM steel units to help deliver more power to the rear wheel.

Key Features:

• CAT5 Aluminum Construction – Machined from aerospace-grade aluminum using a specially formulated alloy developed to Vortex's exact specifications
• 100% CNC Manufactured in the USA – Precision machined to tight tolerances for consistent fit and performance
• Saber Tooth Groove Design – Vortex's patented unique tooth profile increases sprocket longevity and improves chain engagement
• 530 Chain Pitch – Designed for 530-pitch chain applications
• 47 Teeth – Provides strong low-end acceleration and top-end pull suited for high-displacement sportbike applications
• Black Anodized Finish – Color anodizing applied to the sprocket face while sweeps, mud grooves, and teeth retain bright silver machined highlights for a distinctive two-tone appearance
• Weight Reduction – Significantly lighter than OEM steel sprockets, reducing unsprung and rotating mass

The Vortex CAT5 series is a favorite among track day riders and racers seeking a direct OEM-style replacement with a performance and aesthetic upgrade. The MPN 436ZK-47 is sold individually as a single rear sprocket.
