The Supertech dual valve spring kit for Nissan RB26DET 24-valve engines supplies paired springs to enhance valve control and resist float at higher engine speeds. The dual-spring setup aims to keep valve seating consistent under load while offering additional margin over single-spring configurations. It’s intended for RB26DET 24V applications where stronger valve retention is desired.
