Description

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

These PRO SPRINGS suit the Nissan FJ20 DET Twin Cam engine.

These springs are highly recommended for applications over 250rwkw , 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 40-50 psi seat pressure, once 15 psi is added to this equation (which acts against the valve spring), approximately only 30 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 spring – straight drop in
  • OEM retainers can be retained
  • NITRIDE TREATED and shot peened Spring.
  • Inner 38.1mm – 50Lbs – Outer 34.9mm – 80lbs

      Quality Aussie made Drop in valve spring!
