The Rear Sprocket 48T 5.25 BC 520 Chain by M AND W ALUMINUM PRODUCTS is a precision-engineered drive component designed for micro sprint racing applications where lightweight construction and reliable power transfer are mission-critical. Built from aerospace-grade aluminum, this 48-tooth rear sprocket delivers the exact gear ratio needed for competitive sprint racing platforms that demand minimal rotational mass without sacrificing durability. Whether you're optimizing acceleration or fine-tuning top-end performance, this sprocket represents the engineering standard trusted by racers who understand that every tenth counts.
Manufactured with a 5.25-inch bolt circle pattern, this rear sprocket integrates seamlessly with 520-chain drivetrain systems common to micro sprint platforms and select high-performance applications. The 48-tooth configuration delivers a moderate gear ratio suited for oval track racing where mid-range torque and predictable engagement are essential. Aluminum construction reduces unsprung weight compared to steel alternatives, improving acceleration response and chassis dynamics without introducing flex under load. The natural finish preserves material integrity while resisting corrosion inherent to racing environments, and the precise tooth geometry ensures positive chain engagement and minimal noise during operation.
This sprocket is ideal for sprint racers and drive-system builders who need OEM-quality replacement or upgrade components for micro sprint platforms or compatible 520-chain systems. Weighing just 0.83 pounds, the Rear Sprocket 48T 5.25 BC 520 Chain integrates directly into existing drivetrain architecture without modification, making it a straightforward bolt-on upgrade for teams seeking incremental performance gains. Verify bolt pattern compatibility and chain width before installation to ensure proper alignment and chain tension during operation.
