GSC 5073 conical valve springs deliver superior harmonic damping compared to traditional designs, making them ideal for high-RPM and high-boost Subaru turbo applications. The varying coil diameter naturally reduces valvetrain shock and stress, extending component life under extreme conditions. Multi-step heat treatment and super-finished surfaces ensure reliability when pushing aggressive cam profiles and elevated boost levels.
