B38 Valve Spring Kit | Ferrea Racing | BMW MINI

The Ferrea B38 Valve Spring Kit is engineered to eliminate three of the most common causes of engine failure in performance builds: binding, breakage, and valve float. Designed for BMW MINI B38 engines, these high-performance valve springs deliver the stability and strength required for high-lift camshafts, high RPMs, and demanding turbocharged applications.

Why Choose Ferrea B38 Valve Springs?

• No Binding – Ensures valves open and close smoothly without interference, protecting against severe engine damage.
• No Breakage – Built from premium alloys and heat-treated for strength, reducing the risk of dropped valves and catastrophic failures.
• No Valve Float – Provides higher spring pressure than OEM springs, preventing power loss and combustion leaks at high RPM.

Each kit is meticulously heat-treated, stress-relieved, and designed to minimize load loss while maintaining superior durability. Ferrea retainers are CNC-machined for precision and strength, while spring seat locators made from 4140 chromoly alloy ensure perfect tolerances and wear resistance with a hard Nitrided surface treatment.

For tuners and engine builders pushing the limits of the BMW MINI B38 platform, Ferrea’s valve spring kit delivers unmatched reliability, power, and protection against the common pitfalls of OEM springs.

Installation requires the expertise of an engine builder.
