Kelford Cams RB25DET NEO Valve Springs
Suits Nissan RB25DET NEO engines
Kelford Cams offer two variations of valve springs for the RB25DET NEO engine, the KVS25NEO-DI set and the KVS25NEO set.
This kit (KVS25NEO-DI) is a set of drop-in parallel springs to suit OEM retainers and include only the RB25 NEO valve springs (no retainers or seats). The second option (KVS25NEO) utilises a beehive vale spring, for higher RPM and high boost applications. The Beehive design reduces the chance of valve float (when the valves don’t close properly at high RPM). For higher level applications, the titanium valve spring set is recommended, view it here.
As a minimum, Kelford Cams recommend to upgrade to this set of valve springs for RB25DET NEO camshafts operating above 7500RPM or 14PSI of boost.
