Vortex 347ZK-48 CAT5 Black Aluminum Rear Sprocket 48-Tooth

The Vortex 347ZK-48 is a CAT5 Series aluminum rear sprocket featuring a black anodized finish and 48-tooth count, engineered for high-performance motorcycle applications. Manufactured 100% in the USA, this sprocket is a lightweight, precision-crafted alternative to heavy OEM steel sprockets.

Vortex's CAT5 process involves anodizing the sprocket first, then CNC machining it from a specially formulated aluminum alloy — resulting in a sprocket with vivid color contrast and machined silver highlights on the teeth and sweep areas. Every unit is held to the tightest manufacturing tolerances for perfect concentricity, which reduces drivetrain wear and frees up horsepower.

Key Features:

• 48-Tooth rear sprocket for flexible gearing options
• Black anodized CAT5 finish with machined accent highlights
• 100% CNC manufactured in the USA
• Specially formulated aluminum alloy per Vortex specifications
• Lightening holes reduce rotating mass for improved acceleration
• Vortex patented unique tooth design increases sprocket longevity and reduces chain wear

Whether you're on the track or the street, the Vortex 347ZK-48 delivers the performance, durability, and distinctive look that racers and enthusiasts demand from a trusted American-made brand.
