Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kit for Honda's B-series VTEC engines. Each kit includes Skunk2's high-quality dual valve springs and race-proven titanium retainers that are the result of nearly two decades of racing and engine building experience. Each Alpha Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm. 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.

All Skunk2 products are carefully planned and designed in-house using the latest computer simulation and modeling techniques, followed by careful testing in controlled laboratory environments using state-of-the-art equipment. Each product is then subjected to rigorous dyno, street, and race track testing to ensure proper performance in the most extreme conditions. For these reasons, top street cars and race cars worldwide rely on Skunk2 products.
