Skunk2 908050300 B16 Titanium Valve Spring Retainer Set Honda B-Series VTEC

The Skunk2 908050300 is a precision-engineered titanium valve spring retainer set designed for Honda B16-series VTEC engines. Built to significantly reduce valvetrain mass, these retainers deliver measurable horsepower gains and improved valvetrain stability at high engine speeds — making them a go-to upgrade for performance and racing builds alike.

Key Features:

• Medical-grade titanium construction — manufactured exclusively from ultrasonically inspected and certified 6AL4V titanium for maximum strength and minimum weight
• 42% lighter than OEM steel retainers — reduced valvetrain mass translates directly to improved high-RPM response and power output
• Radius-cut edges for additional rocker arm clearance and further weight reduction
• Strategically positioned lightening grooves and reduced overall height for improved valve seal clearance
• CNC machined and individually inspected — each retainer is verified for proper hole diameter, taper, and freedom from machining defects to ensure correct installed valve spring heights and pressures
• CAD/FEA optimized design — engineered using 3D Computer Aided Design and Finite Element Analysis for the ideal balance of strength and reduced weight
• Serialized for quality assurance — each retainer carries a unique serial number encoding material batch specifics, production date, and inspection date
• Dyno and race track proven — validated in environments exceeding 11,000 RPM drag racing engines

Skunk2 designs, develops, and tests its entire valvetrain lineup in-house, ensuring every component meets the demands of competitive motorsport.
