Vortex 435AV4-49 Aluminum Rear Sprocket 520 Pitch 49-Tooth Anodized Violet

The Vortex 435AV4-49 is a 49-tooth, 520-pitch aluminum rear sprocket machined to race-proven tolerances for street and track riders. Built as a lightweight, high-performance upgrade over a heavy steel OEM sprocket, this sprocket delivers real gains in acceleration and throttle response by reducing rotating mass in the drivetrain.

Key Features:

• 49 Teeth, 520 Pitch — direct replacement or compatible 520 conversion application
• 7075 T6 Billet Aluminum — aerospace-grade alloy chosen for its exceptional strength-to-weight ratio
• 100% CNC Machined in the USA — manufactured to the tightest tolerances for a perfectly concentric sprocket every time
• Anodized Violet (AV4) Finish — CAT5 color anodizing provides a bright, corrosion-resistant finish
• Vortex Patented Tooth Design — unique saber-tooth groove geometry reduces drag, minimizes friction, and extends sprocket and chain longevity
• Reduced Rotating Mass — lighter drivetrain components improve acceleration, deceleration, and directional response
• Available in single-tooth increments for precise gearing tuning

Vortex sprockets are trusted by professional race teams worldwide and are engineered to meet the demands of both competitive racing and aggressive street riding. The clear anodized finish and mud-clearing tooth grooves help protect against corrosion and keep drivetrain components running cleanly.
