Alpha Series Honda D Series VTEC Valve Spring Set

These kit includes Alpha Series valve springs made from supper-clean chrome-silicone wire and designed to prevent valve float and maintain valvetrain stability and titanium retainers designed to significantly reduce valvetrain mass which results in both improved valvetrain stability and increased horsepower. With radius-cut edges these retainers provide additional rocker arm clearance and weight reduction. Skunk2's Alpha Valve Springs and Titanium Retainers are a product of the company's years of racing and engine building experiences. Like all of its valvetrain components Skunk2 designs develops and tests its valve spring and retainer lineup in-house to ensure superior quality and maximum performance gains. During development each valvetrain component is tested both on the dyno and the road. Skunk2's industry-leading Alpha Titanium Retainers are designed to significantly reduce valvetrain mass resulting in more horsepower and improved valvetrain stability. Similar to Skunk2's already popular Pro Series Titanium Retainers Alpha Titanium Retainers feature radius-cut edges for additional rocker arm clearance and reduced weight strategically positioned lightening grooves and reduced overall heights for better valve seal clearance and even further weight reduction. Alpha Titanium Retainers are manufactured using the latest 3D CAD Computer Aided Design and FEA Finite Element Analysis to ensure that each is optimized for strength as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno as well as the race track. Once approved for manufacturing only medical-grade titanium that's been ultrasonically inspected and certified is used. Following CNC machining each retainer is then individually inspected to ensure proper hole diameter taper and that each are free from machining defects to ensure proper installed valve spring heights and pressures. Finally each retainer is serialized for your protection including valuable information like material batch specifics as well as production and inspection dates.
