Skunk2's Alpha Series kit pairs dual valve springs with titanium retainers for Honda B-series VTEC engines (B16A, B17A, B18C). The chrome-silicone springs use inner and outer coils at differing frequencies to prevent valve float and hold valvetrain stability past 10,000 rpm, while the titanium retainers cut reciprocating mass with radius-cut edges and lightening grooves for extra rocker clearance.
