Alpha Valve Spring and Titanium Retainer Kit

The Skunk2 Alpha Valve Spring and Titanium Retainer Kit is engineered for Honda's B-series VTEC engines, offering a significant upgrade for high-performance applications. The Alpha Valve Springs are constructed from premium, chrome-silicone wire sourced from Japan. Utilizing an inner and outer spring design with differing frequencies, these springs effectively prevent valve float and ensure consistent valvetrain stability, even at engine speeds exceeding 10,000 rpm. Skunk2's industry-leading Alpha Titanium Retainers are engineered using advanced 3D CAD and FEA to optimize strength while minimizing weight. Features include radius-cut edges for improved rocker arm clearance, strategically placed lightening grooves, and reduced overall heights for better valve seal clearance. These retainers are manufactured from medical-grade titanium, ultrasonically inspected and certified for quality. Each retainer undergoes individual inspection post-machining to guarantee proper dimensions and defect-free construction, ensuring correct installed valve spring heights and pressures. This kit is compatible with a range of Honda and Acura models, including the 1992-2001 Acura Integra GS-R, 1997-1998 & 2000-2001 Acura Integra Type R, 1999-2000 Honda Civic Si, and 1994-1997 Honda Civic del Sol VTEC.
