Description
If you’re running a chain drive system that demands reliability under high RPM loads, sprocket wear directly impacts your power delivery and acceleration response. The SUPERSPROX 42-tooth rear sprocket delivers race-proven durability with a lightweight design that reduces unsprung mass without sacrificing strength—ideal for both track days and demanding street or off-road use.
Built using CAD design and CNC-laser cutting, this sprocket achieves precise tooth geometry for smooth engagement and extended chain life. The exclusive 2XZINK anti-corrosion black finish resists oxidation in harsh conditions while maintaining the aggressive aesthetic you expect from a performance drivetrain component.
