The Vortex 312ZB-43 is a precision-engineered aluminum rear sprocket designed for 415 pitch chain applications. This high-performance sprocket features 43 teeth and is manufactured from aerospace-grade 7075 aluminum alloy, offering an exceptional strength-to-weight ratio that reduces rotating mass and improves acceleration and handling.

Key Features:

• 100% CNC machined in the USA for precise concentricity and durability
• Constructed from 7075 aircraft-grade aluminum for maximum strength and minimal weight
• Vortex patent-pending saber tooth groove design increases sprocket longevity
• Blue anodized finish provides corrosion resistance and distinctive appearance
• Strategic lightening holes reduce unsprung rotating mass
• 415 pitch, 43 teeth configuration

Vortex Racing has been manufacturing championship-winning sprockets since 1995, and their race-proven designs have become the industry standard for lightweight, high-strength drivetrain components. By reducing rotating mass, this aluminum sprocket helps put more power to the pavement while improving throttle response and overall performance.
