Vortex 338ZK-49 520 Aluminum Rear Sprocket 49 Tooth Black

The Vortex 338ZK-49 is a 49-tooth, 520-pitch aluminum rear sprocket finished in a black anodized coating. Engineered for street and performance riding, this sprocket delivers a meaningful reduction in drivetrain rotating mass compared to OEM steel sprockets, translating directly into improved throttle response and quicker acceleration.

Key Features:

• Material: CNC machined from high-strength 7075 T6 aluminum for an exceptional strength-to-weight ratio
• Chain Pitch: 520
• Tooth Count: 49 teeth
• Finish: Black anodized coating for corrosion resistance and durable appearance
• Construction: 100% CNC manufactured to precise tolerances for a concentric, smooth-running sprocket
• Tooth Design: Vortex proprietary tooth profile engineered to extend sprocket and chain longevity
• Mud Grooves: Integrated clearance grooves between teeth help expel debris and keep the drivetrain running cleanly

Vortex sprockets are a popular choice among both track riders and street enthusiasts who want a lightweight, precision-made alternative to stock sprockets. The 338ZK-49 is sold as a single rear sprocket.
