7-1/4 Button Flywheel

The 7-1/4 Button Flywheel from Quarter Master is a precision-engineered component designed for high-performance and racing applications where weight reduction and reliable power transfer are critical. This compact flywheel is engineered for enthusiasts and professional mechanics building street, strip, or road-course vehicles that demand consistent clutch engagement and minimal inertia. Built to replace factory flywheels in compatible applications, the 7-1/4 button design provides the contact surface necessary for modern performance clutch systems while maintaining the lightweight advantage essential for quick acceleration and faster engine spin-down characteristics.

Quarter Master flywheels are manufactured with precision-balanced construction to eliminate vibration and ensure smooth power delivery across the entire RPM band. The button-style friction surface is specifically designed for organic, ceramic, and carbon metallic clutch materials, allowing builders to select the clutch package that matches their vehicle's intended purpose and driving style. Weighing just 3.97 pounds, this lightweight flywheel significantly reduces rotational mass compared to factory iron units, which directly improves throttle response, reduces engine strain during gear changes, and enhances overall drivetrain dynamics. The compact 7-1/4-inch diameter makes it compatible with space-constrained engine bays while delivering the thermal stability and durability required for repeated high-load applications.

This Quarter Master flywheel is ideal for domestic performance vehicles, drag racing applications, road racing setups, and any build where reducing unsprung weight directly improves performance metrics. Proper installation requires a qualified mechanic experienced with clutch systems, as flywheel resurfacing or replacement often coincides with clutch replacement to ensure optimal contact and engagement. Verify compatibility with your specific vehicle platform and clutch assembly before purchase, as button diameter and bolt pattern configuration are critical factors in successful fitment and safe operation.
