HIGH-REV DUAL VALVE SPRING KITS
For vehicles factory equipped with “single” valve springs, Skunk2 offers a high-rev dual-valve spring kit. Dual valve springs are superior to single valve springs at high rpm because the inner and the outer valve springs have different natural harmonic frequencies that help dampen each other and prevent spring surge. Each kit comes complete with new springs bases, valve springs, and titanium retainers.
