Vortex 526AZR-47 Conversion Aluminum Rear Sprocket Sprockets - CAT5 520 47-Tooth Red

The Vortex 526AZR-47 is a lightweight CAT5 series aluminum rear sprocket designed for 520 chain conversion applications. Built for serious street and track riders, it delivers a meaningful reduction in rotating mass over standard steel sprockets, translating to sharper throttle response and improved acceleration.

Construction & Finish: The CAT5 sprocket is anodized in color first, then precision CNC machined from 7075 aluminum — a process that yields a distinctively colored body with bright contrasting silver highlights on the machined surfaces, mud grooves, and teeth. The result is a race-quality sprocket that looks as good as it performs.

Key Features:

• 520 Pitch Conversion — 47-tooth rear sprocket designed for 520-pitch chain systems
• 7075 Aluminum Construction — Specially formulated alloy per Vortex specifications for an exceptional strength-to-weight ratio
• 100% CNC Machined in the USA — Manufactured to extremely tight tolerances for precise fit and maximum power transfer
• Anodized-First Process — Color anodizing applied before CNC machining produces vivid color with eye-catching silver machine-cut highlights
• Patented Saber Tooth Design — Vortex's unique tooth geometry promotes clean chain engagement and release, extending sprocket and chain life
• Self-Cleaning Grooves — Mud and debris grooves between teeth help keep the drivetrain running smoothly
• Available in Multiple Colors — Offered in red, blue, gold, and black (color availability varies by application)
• Trusted by Racing Champions — Proven at the track across numerous professional racing programs

The Vortex 526AZR-47 is a direct upgrade for riders looking to reduce unsprung weight and fine-tune their gearing ratio through a 520 chain conversion. All three drivetrain components — front sprocket, rear sprocket, and chain — must share the same 520 pitch when performing a conversion.
