Vortex 438ZRV4-44 Aluminum Rear Sprocket 44T 530 Pitch Black

The Vortex 438ZRV4-44 is a 44-tooth, 530-pitch aluminum rear sprocket finished in Vortex's ZRV4 PTFE black hardcoat. The PTFE hardcoat treatment bonds directly to the aluminum surface, creating a more durable, low-friction finish that resists wear better than standard anodizing.

Machined from 7075-T6 billet aluminum, this sprocket significantly reduces rotating mass compared to stock steel sprockets, contributing to improved throttle response, acceleration, and deceleration. The unique Vortex patented tooth profile is engineered to extend sprocket life and promote smooth, consistent chain engagement.
