Brian Crower BC3900-2 Valve Springs and Titanium Retainers Kit

The Brian Crower BC3900-2 valve spring and titanium retainer kit is a precision-engineered system designed to deliver superior valve control at high RPM and support aggressive camshaft profiles. This matched set combines premium valve springs with lightweight titanium retainers for maximum performance and reliability.

Valve Springs:

• Wound from highest grade super clean chrome silicone alloy for exceptional durability
• Engineered specifically for high RPM applications to prevent premature valve float
• Features proprietary processing procedures including chamfering and deburring
• Maintains consistent spring pressures over long-term high RPM usage
• Supports increased lift camshafts for enhanced performance

Titanium Retainers:

• CNC machined from premium 6AL4V titanium bar stock to exacting tolerances
• Approximately 40% lighter than factory OEM steel retainers
• Reduced reciprocating mass allows for higher RPM operation
• Superior strength-to-weight ratio for ultimate performance

System-Matched Design:

Brian Crower valve spring and retainer kits are engineered to work together as a complete system, providing optimized valve train control at extended RPM ranges. This matched combination allows for greater lift camshafts while improving both performance and reliability over stock components.
