Maximize the performance of your BMW / Toyota B58 engine with the Ferrea Racing Lifter Shim Set. Designed to improve valvetrain stability, these precision shims fit beneath the factory hydraulic lifters, reducing their travel distance. This helps eliminate valve float, ensuring consistent power delivery at high RPMs and under heavy boost.
Prevent Valve Float at High RPMs
In high-revving or turbocharged B58 setups, excess stress on the valvetrain can lead to valve float, where valves stay partially open, resulting in lost performance and potential engine damage. Ferrea lifter shims restore correct lifter clearance, preventing these issues and keeping your engine running smoothly even under extreme conditions.
Maintain Precision Under Boost
Turbo B58 engines face added challenges from boost pressure, making precise valvetrain control essential for avoiding lifter noise, valve control issues, and power loss. While factory lifters work well for daily driving, advanced setups with custom camshafts or high-RPM tuning demand the extra stability these shims provide.
