Vortex 151ZK-37 Steel Rear Sprocket Silver 37-Tooth

The Vortex 151ZK-37 is a steel rear sprocket featuring a 37-tooth configuration in a silver finish. Engineered to Vortex's precise manufacturing standards, this sprocket is built from carbon steel alloy and finished with a silver anodized or electro-plated coating to resist corrosion and maintain a clean appearance over time.

Vortex rear sprockets are well recognized in the motorcycle community for their quality construction and patented tooth geometry. The unique tooth profile is designed to reduce wear and extend sprocket life compared to conventional designs, making it a trusted choice for both street and performance riding applications.

Key Features:

• 37-tooth rear sprocket for fine-tuning final drive gearing
• Carbon steel alloy construction per Vortex specifications
• Silver finish — anodized or electro-plated to prevent corrosion
• Patented Vortex tooth design for increased longevity
• Precision manufactured to ensure proper chain engagement and fitment

Swapping to a different tooth count rear sprocket is a straightforward way to adjust your motorcycle's final gearing — more teeth for improved low-end acceleration, fewer teeth for higher top-end speed. The Vortex 151ZK-37 is a direct bolt-on replacement for compatible applications using the ZK bolt pattern.
