Vortex 427ZUV4-48 Aluminum Rear Sprocket 48-Tooth 530-Pitch Silver

The Vortex 427ZUV4-48 is a 48-tooth, 530-pitch aluminum rear sprocket engineered for riders who demand race-proven performance and reduced rotating mass. Machined from a specially formulated aerospace-grade alloy to Vortex's own specifications, this sprocket delivers an exceptional balance of strength and lightweight construction.

Key Features:

• 48-Tooth / 530-Pitch — direct-fit rear sprocket with standard 530 chain compatibility
• CNC Machined in the USA — 100% CNC manufactured for precise tolerances and consistent concentricity
• 7075-T6 Aerospace Aluminum — specially formulated alloy per Vortex specifications for maximum strength-to-weight ratio
• Silver Anodized Finish — corrosion-resistant anodized coating for long-lasting appearance and protection
• Patented Tooth Design — unique tooth geometry increases sprocket longevity and promotes smooth chain engagement
• Reduced Rotating Mass — lighter than OEM steel sprockets, contributing to improved acceleration and throttle response

Vortex rear sprockets are a trusted choice among racers and performance riders. The lightweight aluminum construction reduces unsprung and rotating weight compared to stock steel sprockets, translating to sharper acceleration and more responsive handling. The silver anodized finish resists corrosion and keeps the sprocket looking clean through hard use.
