Product Details

The Vortex 427AZK-39 is a high-performance aluminum rear sprocket featuring 39 teeth and Vortex's proprietary CAT5 hard-anodizing process. Designed for 427 conversion chain applications, this sprocket delivers an excellent balance of lightweight construction and enhanced durability for sport and track motorcycles.

Key Features:

  • CAT5 hard-anodized finish provides superior wear resistance and extended service life
  • Precision CNC-machined from high-grade 7075-T6 aluminum alloy
  • 39-tooth configuration for optimized gearing ratios
  • Self-cleaning mud grooves help prevent debris buildup
  • Significantly lighter than steel sprockets for reduced unsprung weight
  • Compatible with 427 pitch chains

Vortex sprockets are manufactured to exacting tolerances to ensure proper chain engagement and smooth power transfer. The CAT5 anodizing process creates a hard surface layer that resists wear while maintaining the weight advantages of aluminum construction.

Just a rating for shopping experience. 4* only because purchase could not be completed w/Apple Pay

Easy to find parts and easy checkout
