Release Bearing Piston 1.615 OAL

The Release Bearing Piston 1.615 OAL from Tilton (model 62-6004) is a precision hydraulic clutch component engineered for high-performance manual transmissions and competition vehicles. This piston sits at the heart of Tilton's hydraulic release bearing assemblies, translating hydraulic pressure into mechanical clutch disengagement with minimal lag and maximum repeatability. Whether you're building a road-racing setup, autocross platform, or street performance car with a custom clutch system, this component ensures crisp, linear pedal feel and reliable operation across thousands of heat cycles.

Tilton's release bearing pistons are machined to exacting tolerances and finished to resist corrosion and wear in demanding environments. The 1.615-inch overall length of this piston is calibrated to work within Tilton's modular hydraulic release bearing housings, ensuring proper stroke, actuation force, and return characteristics. The compact 2.5 x 2 x 2.5-inch footprint and lightweight 1-pound design minimize unsprung mass while maintaining structural rigidity under clutch load. Internal geometry is optimized for even pressure distribution, preventing binding and extending service life in high-rpm applications where thermal cycling and shock loads are constant.

Mechanics and fabricators restoring or upgrading hydraulic clutch systems commonly specify Tilton release bearing assemblies for their durability and predictable performance. This piston is ideal for custom fabrication work, vintage race car builds, or OEM system repairs where original components are unavailable or undersized for increased torque loads. Before installation, verify compatibility with your Tilton release bearing housing model and confirm that your hydraulic lines, master cylinder, and slave cylinder are properly sized and bled. Proper assembly and fluid maintenance ensure years of fade-free clutch engagement.
