Brian Crower BC3961 Valve Springs and Titanium Retainers Kit

The Brian Crower BC3961 valve spring and titanium retainer kit delivers precision-engineered valve train components designed for high-performance and high-RPM applications. This system-matched kit combines premium valve springs with lightweight titanium retainers to provide superior valve control, prevent valve float, and support aggressive camshaft profiles.

Valve Springs:

• Manufactured from highest grade super clean chrome silicone alloy
• Proprietary processing procedures including chamfering and deburring for consistent spring pressures
• Engineered to prevent premature valve float at extended RPM ranges
• Maintains consistent seat and open pressures over long-term use

Titanium Retainers:

• CNC machined from premium 6AL4V titanium bar stock to exact tolerances
• Approximately 40% lighter than OEM steel retainers
• Reduced reciprocating mass improves valve train dynamics and allows higher RPM operation
• Precision matched to work seamlessly with included valve springs

Complete System Benefits:

• System-matched components engineered to work in unison for optimal performance
• Supports greater lift camshafts for increased performance potential
• Improved valve control at high RPM for enhanced reliability
• Essential upgrade for modified engines with performance camshafts

This kit provides the critical valve train components needed to support performance builds requiring reliable operation at elevated engine speeds and camshaft lift profiles.
