      Description
      This is the perfect spring and retainer option for your Built B-Series Street Car. In addition to superior spring geometry, the entire They are processed with premium grade alloy and feature special thermal treatment to provide top of the line performance in the most abusive conditions. Factory valvesprings were not made to handle the abuse of higher lift and duration, especially not at the rpm we take our engines to when racing, or even driving enthusiastically. If you are installing upgraded cams, do yourself a favor and install valvesprings and retainers while you're in there.

      Your stock valve springs can fail in 3 different ways:

      • BIND - They can "bind" and get stuck, losing their ability to open and close the valve. This is an easily diagnosable failure. Depending on how it binds, it could cause failure to other engine parts.
      • BREAK - They can "break" into pieces dropping the valve into the combustion chamber and consequently ruining your bottom end.
      • FLOAT - "Valve Float" is a hard to diagnose condition where the valve spring rate is not high enough to fully extend the spring and close the valve after a complete rotation of the cam before the cam comes back around again. So what ends up happening is that when the cam is spinning fast (high rpm) the valve never closes, and combustion leaks out of the engine, and the engine loses power.

      All three of these conditions can be avoided by using these Ferrea Valve Springs and Ti Retainers.


      Ferrea Beehive Valve Springs feature a variable rate changing diameter coil geometry that increases spring performance on street driven race engines by:

      •     Optimizes Valvetrain Harmonics
      •     Reducing Valvetrain Resonance
      •     Increase Spring Stability
      •     Increase Spring Stability
      •     Reduce Spring+Retainer Mass..smaller and lighter
