Vortex 312DZK-56 Steel Rear Sprocket 56-Tooth Black

The Vortex 312DZK-56 is a 56-tooth steel rear sprocket finished in a dark zinc black coating for enhanced corrosion resistance. Engineered by Vortex Racing — a U.S.-based manufacturer with decades of motorsport heritage — this sprocket is built to meet the demands of street, track, and performance riding applications.

Vortex steel rear sprockets are manufactured from carbon steel and feature an electro-plated satin black finish. The hardened teeth provide long service life without sacrificing sprocket strength, making this an ideal choice for riders who prioritize durability over the weight savings of aluminum. The 56-tooth count provides a taller rear gear ratio, increasing low-end torque and acceleration off the line.

Key Features:

• 56-Tooth rear sprocket for increased low-end torque and acceleration
• Carbon steel construction with hardened teeth for exceptional durability
• Dark zinc black finish for corrosion resistance and aggressive styling
• Precision manufactured to tight tolerances for accurate concentricity
• Vortex patented tooth profile design for extended sprocket longevity
• 100% designed and manufactured in the USA by Vortex Racing

Vortex Racing components are tested on the track with direct feedback from top professional race teams worldwide. The 312DZK-56 is a direct bolt-on replacement that delivers reliable performance mile after mile. Always ensure the front sprocket and chain pitch match when upgrading rear sprocket tooth count.
