Vortex 435ZB-48 CAT5 Blue 48-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 435ZB-48 is a high-performance CAT5 series rear sprocket machined from a specially formulated aluminum alloy, offering a significant weight reduction over stock steel sprockets. Designed for 520-pitch chain, this 48-tooth sprocket delivers a direct performance upgrade that improves acceleration by reducing rotating mass in the drivetrain.

Premium Aluminum Construction

• CNC machined from 7075-T6 aluminum for an optimal balance of light weight and durability
• Specially formulated alloy developed to Vortex's own specifications
• Reduced rotating mass multiplies weight savings across the entire drivetrain
• Less rotating weight translates directly to improved throttle response and acceleration

Precision CNC Manufacturing

• 100% CNC manufactured in the U.S.A. to the tightest tolerances
• Proprietary manufacturing process produces a perfectly concentric sprocket every time
• Saber tooth groove design reduces friction and drag for improved acceleration and deceleration
• Unique tooth geometry extends the service life of both the sprocket and chain

CAT5 Series Design

• Features Vortex's patented CAT5 design with blue anodizing that excludes the sweeps, mud grooves, and teeth
• Results in a striking flash of blue color with bright silver highlights on the machined surfaces
• Mud grooves help keep drivetrain components clean during operation
• Available in single-tooth increments for precise gearing customization
• Designed for 520-pitch OEM replacements or suitable conversions to 520-size chain and sprockets

The 435ZB-48 is part of Vortex's proven CAT5 lineup, built for riders who demand performance-grade components without compromising on style. Note: Sprocket shape and bolt pattern will vary by application; confirm fitment before ordering.
