Vortex 438ZLV4-45 VTX Aluminum Rear Sprocket 45T

The Vortex 438ZLV4-45 is a high-performance 45-tooth aluminum rear sprocket from Vortex Racing's VTX series. Engineered for performance-oriented street and track riders, this sprocket delivers a lightweight alternative to stock steel units without sacrificing durability.

Manufactured from aerospace-grade 7075 aluminum, the ZLV4 series sprocket undergoes a hard-anodizing process that creates an exceptionally tough surface layer, significantly extending wear life compared to standard anodized aluminum sprockets. The result is a component that sheds weight from the drivetrain while maintaining the strength needed for aggressive riding conditions.

Key Features:

• 45-Tooth configuration for optimized acceleration and drive feel
• 7075 hard-anodized aluminum construction for maximum strength-to-weight ratio
• ZLV4 series design with precision CNC machining for true, consistent tooth profile
• Lightweight design reduces unsprung and rotating mass for improved throttle response
• Corrosion-resistant hard-anodized finish for long service life
• Designed to OEM-matching fitment specifications for a direct bolt-on installation

The Vortex VTX rear sprocket is a popular upgrade for riders looking to fine-tune their gearing for track days or spirited street riding. Compatible with the appropriate chain pitch as specified by the 438 designation in the part number.
