Skunk2 Alpha valve spring and titanium retainer kit for B‑series VTEC combines dual chrome‑silicone springs with race‑proven titanium retainers. Alpha springs use inner and outer springs tuned to resist valve float above 10,000 rpm; the lightweight titanium retainers reduce valvetrain mass and feature radius‑cut edges and lightening grooves. Kit specs include 68 lbs seat and 210 lbs open pressures.
