Description

Ferrea valve springs for BMW S54 engines address binding, breakage, and valve float. They are heat-treated and stress-relieved for stability in high-lift and high-RPM applications. Precision CNC-machined retainers are crafted from high-strength materials. Ferrea Spring Seat Locators are made from 4140 chromoly alloy with a Nitrided surface treatment for toughness and wear resistance. Upgrading ensures proper valve operation, maximizes engine power, and reduces engine failure risk.
