  ** As Used by Australia’s leading Workshops – your guarantee of performance and reliability **

These PRO SPRINGS suit all BA/BF and FG Ford DOHC 6 cylinder Barra 4.0L engines. Suitable for applications up to 550+rwkw.

These springs are highly recommended for applications over 300rwkw (400hp), to help eliminate valve float. Valve float causes damage to valve stem seals and collets and retainers.

Once installed, a much more powerful and free revving top end power curve is possible. OEM valve springs have approx 50 psi seat pressure, once 15 psi is added to this equation (which acts against the valve spring), approximately only 35 psi seat pressure is left. This is nowhere near enough to keep the valves closed at high rpms.

 FEATURES :

  • New and Improved design 
  • Direct replacement for the OEM Bee-Hive style spring – straight drop in
  • OEM retainers can be used (titanium replacements recommended for hp above 520rwkws – see other listings)
  • NITRIDE TREATED OVATE Style Spring.
  • 98Lbs X 240Lbs at .500 lift( thats approx 75% more than factory)

      Premium quality – We guarantee these to be the best quality ovate style valve springs available on the open market!
