Vortex 505ZK-46 Black 46-Tooth 530-Pitch CAT5 Aluminum Rear Sprocket

The Vortex 505ZK-46 is a 46-tooth, 530-pitch CAT5 aluminum rear sprocket finished in black anodize with contrasting silver machined highlights. Engineered for street and track riders who demand lightweight performance without sacrificing durability, this sprocket is a direct upgrade over heavy OEM steel units.

Key Features:

• Lightweight CAT5 aluminum construction — significantly reduces rotating mass compared to stock steel sprockets, improving acceleration and throttle response
• 100% CNC manufactured in the USA to precise tolerances for concentricity and consistent chain engagement
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• Vortex patented tooth design promotes even wear and increases sprocket longevity
• Black anodized finish with bright silver machined accents on sweeps and mud grooves for a distinctive appearance
• 530 chain pitch — must be paired with a compatible 530-pitch chain and front sprocket
• 46-tooth rear sprocket — ideal for tuning low-end torque and mid-range pull

Vortex Racing sprockets are a trusted choice among racers and performance street riders alike. Reducing rotational weight at the rear wheel translates directly to faster acceleration and sharper handling. Always replace the chain and front sprocket together when installing a new rear sprocket for maximum drivetrain longevity.
