600 Rear Sprocket 6.43in Bolt Circle 56T

The 600 Rear Sprocket 6.43in Bolt Circle 56T is a precision-engineered drivetrain component purpose-built for micro sprint racing applications where lightweight construction and exact tooth count directly impact acceleration and top-end performance. Manufactured by Ti22 PERFORMANCE, a respected name in sprint racing technology, this 56-tooth sprocket delivers the gear ratios necessary for competitive track environments where every fraction of a second counts. Designed for racers who demand reliability under sustained high-RPM conditions, this sprocket integrates into bolt-pattern-specific systems where repeatability and durability are non-negotiable.

Machined from aluminum alloy in natural finish, the 600 Rear Sprocket maintains a lightweight profile at just 1.24 lbs while retaining the structural integrity required for sustained torque transmission in racing drivetrains. The 6.43-inch bolt circle accommodates standard micro sprint axle configurations, ensuring seamless fitment without modification. The 56-tooth design optimizes engine power delivery across the mid-range to top-end RPM band, a critical consideration for drivers seeking competitive gear ratios on short-track venues where power band utilization directly affects lap times and consistency.

Micro sprint racers and sprint car teams will find this rear sprocket essential for tuning drivetrain performance to track conditions and engine specifications. Compatibility with 6.43-inch bolt-pattern rear axles makes installation straightforward for teams running standard micro sprint setups. Racers upgrading sprocket ratios for different track layouts or engine modifications should verify bolt pattern and sprocket bore diameter before purchase to ensure proper alignment and safe operation at racing speeds.
