BMW S58 Valve Spring Kit - Ferrea - Single - `15-`24. A precision single valve spring from Ferrea for S58 applications, offered as a direct-fit replacement sold per spring. This kit is intended for enthusiasts performing valvetrain refreshes or custom builds who need individual springs for each valve.

These Ferrea single springs provide reliable valve control for the S58 when replacing worn components or assembling a modified head. They are useful for restoring correct seat and open loads and for builders who prefer to source springs individually to match retainers, locks, and camshaft profiles. The single-spring format lets you address specific valves without purchasing full sets, and Ferrea’s production focus on valvetrain components makes these a practical choice for performance-minded maintenance and light modification projects.
