5.5 Button Flywheel Pro and V-Drive

The 5.5 Button Flywheel Pro and V-Drive from QUARTER MASTER is engineered for high-performance racing applications, specifically targeting street performance, bracket racing, and dedicated track vehicles. This compact flywheel assembly is designed for drivers and mechanics who require precision engineering for optimal engine response and drivetrain consistency.

The 5.5-inch button design integrates seamlessly with modern clutch systems, optimizing performance through reduced rotational mass while maintaining the structural integrity necessary for high-horsepower applications. The V-Drive feature enhances compatibility across various clutch packages, allowing for flexible drivetrain tuning without sacrificing engagement quality or durability.

Performance enthusiasts working on manual-transmission vehicles, especially those competing in drag racing or road racing, will benefit from this flywheel's ability to minimize driveline parasitic loss. Weighing just 2.15 pounds, it ensures consistent friction engagement across repeated launch cycles, enabling repeatable 60-foot times in competitive environments.
