Ferrea

Ferrea is a valvetrain brand, and the range here is engine valves and valve spring kits. Valves are sold as sets of 8, for intake or exhaust, in 5000 Series and 6000 Series, and in Flo and S-Flo head shapes with radius groove or flat head designs. Spring kits are listed as single spring, dual spring and turbo spring kits.

Every listing is matched to an engine rather than a truck. Titles name engine codes such as K20, B16A1, B17A1, B18C1, D16Z6, EJ20, VR38DETT, N54, S58 and B58. Titles carry the valve dimensions in millimetres and an angle in degrees, with stock-size and oversize options (for example +1mm).

Choose by engine code first, then by position: intake and exhaust valves are not interchangeable, so check which one the title lists. Match the stock size or an oversize to your cylinder head work, and read whether it is a 5000 Series or 6000 Series part. Spring kits are listed per engine and are single or dual spring, depending on the setup. Always compare the engine code in the title with your engine before you order.
