Description

Sport valve spring set from Ferrea made of high quality tempered steel with TITAN spring plates for your Focus RS.

The Ford standard springs have the big disadvantage that they can break or jam the valve springs on engines with a significant power increase and at higher revs. Both problems lead to a capital engine damage! These valve springs have an extra adapted spring rate for high performance. 

Ferrea valve springs are made of an extremely heat-resistant alloy.

Ferrea's valves offer the following advantages:

  • High temperature resistance
  • Strong tensile strength
  • Heat treated material
  • High strength steel
  • Quality and processing at the highest level
  • Titanium spring retainer

Included in the kit:

  • 8 springs exhaust
  • 8 springs intake
  • Topspring retainer made of titanium
  • Steelspring retainer bottom
  • 16 valve wedges

Ferrea is also used in major racing series such as Formula 1, Indy, Nascar and drag racing.
