Vortex 454ZB-43 Aluminum Rear Sprocket Chain Sprockets - CAT5 525 43-Tooth Blue

The Vortex 454ZB-43 is a CAT5 Series aluminum rear sprocket designed for high-performance street and racing applications. Featuring 43 teeth and compatibility with a 525 chain, this sprocket delivers a precise, lightweight alternative to heavy OEM steel units without sacrificing durability or strength.

The CAT5 manufacturing process sets this sprocket apart: it is anodized first in vibrant blue, then precision CNC machined from premium 7075-T6 aluminum, resulting in a striking finished appearance with contrasting silver highlights on the teeth, sweeps, and grooves. This process ensures the anodized color is integral to the sprocket — not just a surface coating.
