BMW S58 Lifter Shim Set by Ferrea

The Ferrea Racing Lifter Shim Set is designed to optimize the performance of BMW S58 engines by improving valvetrain stability. Installed beneath the stock hydraulic lifters, these precision shims reduce lifter travel distance, preventing valve float and enhancing power delivery under demanding conditions.

Prevent Valve Float at High RPMs

Whether you're running high-boost setups or pushing high RPMs, valve float can become a serious issue. This occurs when the valves fail to close properly, leading to a loss of power and potential engine damage. By restoring proper clearance, Ferrea’s lifter shims ensure that your engine maintains stability and delivers peak performance.

Maintain Precision Under Boost

For turbocharged engines like the S58, these shims keep the valvetrain tight and responsive under extreme conditions, preventing issues such as lifter noise or loss of valve control. While the stock hydraulic lifters perform well on the street, serious engine builds—especially those with custom camshafts or tuned for high RPMs—demand the additional precision that lifter shims provide.

Whether you’re building for racing, drag, or track-focused applications, the Ferrea Racing Lifter Shim Set offers your valvetrain necessary reinforcement.
