Ferrea Lifter Shim Set for BMW S55 Engines

The Ferrea Racing Lifter Shim Set is specifically designed to optimize the valvetrain stability of BMW S55 engines, delivering smooth, consistent performance at high RPMs and under demanding conditions. These precision-engineered shims fit beneath the stock hydraulic lifters to limit lifter travel, preventing valve float and improving throttle response. Whether you’re running high-boost setups or prepping your car for competitive motorsport, this lifter shim set offers the reinforcement necessary to keep your S55 engine at peak performance.

Prevent Valve Float and Protect Engine Health

Valve float—where valves remain open longer than intended—can result in power loss and potential engine damage. With Ferrea’s lifter shims installed, your S55 engine maintains precise valve operation, ensuring smooth function under extreme loads. These shims restore proper lifter clearance, protecting the engine during aggressive driving, racing, and high-stress conditions.

The turbocharged BMW S55 demands precision valvetrain control to handle high power levels and boost pressure. Ferrea’s lifter shims eliminate lifter noise, prevent erratic valve operation, and enhance power delivery across the RPM range. Whether your build includes custom camshafts or a high-RPM tune, these shims provide the stability required for track-focused builds, drag racing, or spirited street driving.

Designed for enthusiasts who demand reliability and performance, the Ferrea Racing Lifter Shim Set is a proven solution to reinforce your S55 valvetrain. Keep your engine responsive, stable, and competitive under any conditions with Ferrea’s trusted engineering.
