Vortex 839CZB-48 Aluminum Rear Sprocket 48 Tooth CAT5 Black

The Vortex 839CZB-48 is a high-performance aluminum rear sprocket featuring 48 teeth with a durable CAT5 hard-coat black finish. Engineered for serious riders who demand precision and longevity, this sprocket is 100% CNC manufactured in the USA from specially formulated 7075-T6 aluminum alloy, the best grade material for achieving optimal strength-to-weight ratio.

Key Features:

• 48-tooth rear sprocket with CAT5 black hard-coat anodized finish
• Lightweight aluminum construction reduces rotating mass for improved acceleration
• 100% CNC machined to exacting tolerances for perfect concentricity
• Manufactured from premium 7075-T6 aluminum alloy per Vortex specifications
• Patented tooth design increases sprocket longevity and reduces friction
• Hard-coat anodized finish provides superior wear resistance and corrosion protection
• Precision manufacturing ensures smooth power transfer and extended chain life

Vortex Racing sprockets are engineered to deliver the performance advantage that racers and enthusiasts demand. The reduced weight of aluminum sprockets versus steel significantly decreases rotating mass, which translates directly into quicker acceleration and improved handling response. The patented tooth profile design minimizes drag and friction while the CNC manufacturing process creates a perfectly concentric sprocket that frees horsepower and maximizes drivetrain efficiency.
