Skunk2 Alpha Series Honda/Acura B Series Valve Spring and Titanium Retainer Kit

Take your engine to the next level with the Skunk2 Alpha Series Valve Spring and Titanium Retainer Kit. This kit is designed for Honda's B-series VTEC engines and includes high-quality dual valve springs and race-proven titanium retainers.

Each Alpha Valve Spring is manufactured from super-clean, chrome-silicone wire milled in Japan, ensuring exceptional durability and performance. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs prevent valve float and maintain valvetrain stability at engine speeds over 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. Featuring 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 further weight reduction.
