Description

Designed to eliminate valve float in high-RPM Honda K-series and F-series engines, essential for engines pushed beyond stock RPM limits. Dual-spring design for aggressive aftermarket camshaft profiles, crafted from Super Clean Chrome Silicon Vanadium Steel Alloy for high-cycle fatigue stress. Includes 16 dual valve springs, 16 titanium retainers, and 16 seat locators. Titanium retainers are 40% lighter than steel, reducing valvetrain reciprocating mass. Ideal for high-RPM street or track builds with camshafts up to 15.3mm lift.
