Release Bearing Only 10.5

The Quarter Master Release Bearing Only 10.5 (MPN 106033) is a replacement throwout bearing designed for Quarter Master 721-Series clutch systems. This bearing assembly serves as the critical interface between your vehicle's clutch pedal and pressure plate, enabling smooth clutch engagement and disengagement during driving. As a wear component, the throwout bearing experiences continuous friction and heat cycles, making periodic replacement essential for maintaining responsive pedal feel and preventing clutch system failure.

The 10.5-inch bearing diameter matches Quarter Master 721-Series specifications and is engineered to handle repeated clutch cycles with minimal noise and play. Weighing just 0.5 lbs, this lightweight component reduces rotating mass while maintaining the durability required for high-performance and street-driven vehicles. The compact dimensions (3 x 1.05 x 4.15 inches) ensure compatibility with standard Quarter Master clutch housings, and the bearing-only configuration allows installation of just the wear item without requiring full system replacement when existing components remain serviceable.

This bearing is ideal for builders, restoration shops, and enthusiasts maintaining Quarter Master 721-Series transmissions. Symptoms requiring replacement include chattering engagement, excessive pedal free play, or grinding noises when the clutch is depressed. The bearing-only option provides cost-effective service, allowing technicians to address wear without full clutch package replacement. Whether restoring a classic vehicle or refreshing a performance drivetrain, this Quarter Master 10.5 release bearing ensures precise clutch modulation and extended system longevity.
