Skunk2 Alpha Series Honda D Series VTEC Valve Spring Set

Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kits for Honda’s B-series VTEC and K-series 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.
