Product Details

The Vortex 436ZK-39 Cat5 Rear Sprocket is a high-performance 39-tooth rear sprocket machined from lightweight aluminum and finished in black. Designed as a direct OEM-style replacement or performance upgrade, this sprocket is part of Vortex's popular Cat5 series, built to deliver precise power transfer and reliable chain engagement lap after lap.

Key Features:

  • 39-Tooth Configuration – Optimized gearing for balanced acceleration and top-end performance
  • Lightweight Aluminum Construction – Significantly reduces unsprung rotating mass compared to steel sprockets
  • Black Anodized Finish – Provides corrosion resistance and a clean, aggressive appearance
  • Cat5 Series – Vortex's precision-machined sprocket line known for tight tolerances and consistent performance
  • Direct Fit Design – Engineered for easy installation with standard sprocket bolt patterns

Vortex Racing is a trusted name in the powersports and motorsports industry, manufacturing sprockets, clip-ons, rearsets, and other performance components for street and track riders. The Cat5 rear sprocket is a popular choice among riders looking to fine-tune their gearing without adding unnecessary weight to the drivetrain.
