The Skunk2 Alpha Series valve spring and titanium retainer kit for Honda D‑series VTEC engines provides high-rpm valvetrain stability and reduced rotating mass. Constructed from Japanese chrome-silicone wire and medical‑grade titanium retainers, the kit prevents valve float beyond 10,000 rpm while lowering valvetrain mass for improved response. Each retainer is CNC machined and inspected for precision and strength.
