Vortex 527ZLV4-43 CAT5 Aluminum Rear Sprocket 530 Pitch 43-Tooth

The Vortex 527ZLV4-43 is a CAT5 series aluminum rear sprocket featuring a 530 pitch and 43 teeth, designed for performance street and road racing applications. Manufactured in the USA from a specially formulated aluminum alloy, this sprocket delivers a meaningful reduction in rotating mass compared to steel alternatives, helping to sharpen throttle response and improve overall drivetrain efficiency.

The CAT5 designation identifies Vortex's premium color-anodized aluminum line, CNC machined to the tightest tolerances with a distinctive color anodizing process that excludes the sweeps, mud grooves, and teeth — leaving those surfaces with contrasting silver machine cuts for a race-ready appearance. The violet (LV4) anodized finish not only adds visual distinction but also provides corrosion resistance.
