Product Description

The Skunk2 344-05-1300 Alpha Series Valve Spring and Titanium Retainer Kit is a high-performance valvetrain upgrade engineered specifically for Honda B-Series VTEC engines in Acura Integra and Honda Civic/del Sol applications. This kit combines premium dual-rate valve springs and ultralight titanium retainers to improve valvetrain stability at very high RPMs - helping prevent valve float when using performance camshafts or pushing the engine beyond stock limits. The springs are wound from super-clean chrome-silicon wire to maintain proper seat and open pressures, while the aircraft-grade titanium retainers significantly reduce reciprocating mass, promoting quicker rev response and improved reliability.

Titanium retainers are precision-machined using advanced CAD and FEA methods, featuring radius-cut edges, lightening grooves, and reduced profile heights for optimal clearance and weight savings. Designed for racing and high-revving engines, this Alpha Series kit enhances valvetrain performance for applications such as 1999-2000 Honda Civic Si, 1994-1997 Civic del Sol VTEC, and 1992-2001 Acura Integra GS-R/Type R. While not compatible with certain Pro Series camshafts, this race-ready kit is ideal for performance builds looking to support elevated RPM limits, more aggressive cam profiles, and improved horsepower potential.
