Skunk2 – Alpha Series Valve Spring and Titanium Retainer Kit – B-Series VTEC

Skunk2 Alpha Series Valve Spring and Titanium Retainer Kit – B-Series VTEC

The Skunk2 Alpha Series Valve Spring and Titanium Retainer Kit is engineered for high-revving Honda and Acura B-series VTEC engines, delivering outstanding valvetrain control and reliability under extreme conditions. Designed for both street and race applications, this kit combines dual valve springs with ultra-lightweight titanium retainers to maintain precise valve motion at elevated RPM.

Each dual spring is wound from premium chrome-silicone wire for consistent pressure and durability. The titanium retainers are CNC-machined and radius-cut for reduced mass, improved strength, and superior heat resistance. Together, the system minimizes valve float, enhances stability, and allows engines to safely reach beyond 10,000 RPM when paired with aggressive cam profiles.

Features:

• Dual chrome-silicone valve springs

• Titanium retainers with precision-machined lightening grooves

• Optimized spring rate for high-lift camshafts

• Maintains valve control under extreme RPM and boost conditions

• Designed for reliability and endurance in performance builds

Applications:

• Honda Civic SiR (92–00) B16A

• Acura Integra GS-R / Type R (94–01) B18C

• Compatible with other Honda B-series VTEC engines
