Brian Crower BC3917 Valve Springs and Titanium Retainers Kit

The Brian Crower BC3917 Valve Springs and Titanium Retainers Kit is a matched valve spring and retainer set (also searched as a valve spring kit or spring and retainer kit) designed for high-rpm engines. The springs and retainers are system matched to work together, giving better valve control at extended rpm and supporting greater-lift camshafts for added performance and reliability.

Key Features:

• Valve springs: Wound from high-grade, super clean chrome silicone alloy, with proprietary processing (including chamfering and deburring) for consistent pressures over long-term, high-rpm use. Quality valve springs are critical in preventing premature valve float.
• Titanium retainers: CNC machined to exacting tolerances from 6AL4V titanium bar stock. Brian Crower titanium retainers typically weigh approximately 40% less than factory OEM steel units.
• System matched: Springs and retainers are designed to work in unison as a kit.

A lightweight retainer and spring combination like this helps the valvetrain stay controlled at higher engine speeds, making it a solid choice for performance builds.
