The Vortex 427ZRV4-43 is a CAT5 V4 aluminum rear sprocket featuring 43 teeth and a 530 pitch, finished in a striking red anodize. Building on the iconic CAT5 design that Vortex introduced in 1995, the V4 generation brings a refined material removal pattern that delivers a 10–15% reduction in weight without sacrificing structural integrity, making it an ideal choice for performance street and track riders.

Key Features:

• CAT5 V4 Design — next-generation pattern with machined faces on both sides for optimal strength-to-weight ratio
• Lightweight Aluminum Construction — approximately half the weight of a comparable steel sprocket
• 100% CNC Manufactured in the USA — machined to tight tolerances using a specially formulated alloy per Vortex specifications
• Patented Unique Tooth Design — saber tooth groove geometry engineered to increase sprocket longevity
• 530 Pitch — designed to match OEM 530-pitch chain and sprocket setups
• 43-Tooth Rear Sprocket — fine-tune your drive ratio for improved acceleration or top-speed characteristics
• Red Anodized Finish — color anodizing applied before cutting for the iconic two-tone machined look with bright silver highlights

Vortex aluminum sprockets are favored by road racers, drag racers, and performance enthusiasts who demand maximum weight savings from their drivetrain. For best results, keep the chain clean and properly tensioned, and inspect the sprocket regularly to maximize service life.
