This Skunk2 Alpha Series kit combines dual valve springs and titanium retainers for Honda/Acura K-series engines. The Japanese chrome-silicone dual springs use an interference fit and differing frequencies to prevent valve float and maintain stability past 10,000 rpm, while the titanium retainers reduce valvetrain mass. Springs are rated at 60 lbs seat pressure at 1.600 in. and 220 lbs open pressure at 1.100 in., with coil bind at 1.000 in.
