Ferrea BMW N54 Valvetrain Kit - Stock Sized Valves

BMW E60/E82/E91/E92 3.0L - DOHC 24 Valve (N54) (2007 - 2010) 

Competition Plus Exhaust/Intake Valves

Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve. To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to thematerial structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip.

Valve Springs

Harmonics or high frequency fatigue is present in all racing engines and will usually destroy the valvetrain if not controlled. Properly designed valve springs will control the dominant harmonics, provide the needed stability, and reduce valvetrain component wear. Ferrea valve springs are developed from high strength alloys, including premium grade chrome silicon steel.

Our springs are heat-treated and stress relieved, which dramatically increases the spring’s life. Our valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for today’s aggressive valvetrain combinations.

Titanium Retainers

Ferrea is pleased to offer our Pro-Series Titanium Retainers including sizes that fit both traditional Domestic springs and Sport Compact springs. Precision CNC-machined from aerospace quality titanium, these Pro Retainers are fully heat-treated and finished to exact tolerances, adding strength while offering a 40% weight reduction over conventional steel retainers. We have available applications for 6, 7, 8 (super 7) and 10 degrees. Examine the overall quality of Ferrea’s Pro-Series Retainers and see why professional engine builders demand Ferrea Racing Components.
