Description

Valve spring performance directly impacts your engine’s ability to maintain precise valve timing under high RPM loads—critical for both naturally aspirated and forced induction builds. The Isky 1.560in Plus-Series springs deliver consistent load rates and reliable damping to prevent valve float while supporting aggressive cam profiles. Whether you’re building a street performer or a dedicated race engine, these dual-spring assemblies provide the stability needed for repeatable, controlled power delivery.
