Key Features

Brian Crower’s dual valve spring and retainer kit features several advanced design elements that set it apart from stock components:

• Constructed from high-grade, super clean chrome silicone alloy wire, BC1200 springs provide excellent strength and fatigue resistance, ensuring reliable operation at high RPMs.
• Proprietary processing procedures enhance spring consistency, pressure stability, and durability, making them suitable for demanding applications.
• Titanium retainers CNC-machined from 6AL4V round bar titanium offer a lightweight yet robust solution, reducing valve train inertia and improving response.
• Precision manufacturing ensures exact fitment and compatibility with the SR20VE cylinder head, with no machine work required for installation.
• Spring pressures are optimized for high-performance use, with a seat pressure of 90 lbs and open pressure of 220 lbs, supporting aggressive cam profiles and high RPM operation.
• Spring coil bind height of 0.910" ensures safe clearance during high-speed valve operation, preventing coil bind and valve float.

Construction & Design

This valve spring and retainer kit is meticulously crafted to meet the demands of high-performance engines. The springs are wound from premium chrome silicone alloy wire, which offers excellent tensile strength, fatigue life, and resistance to heat and corrosion. The proprietary processing techniques involve multiple heat treatments and stress-relief procedures, resulting in springs that maintain consistent pressure over extended use.

The titanium retainers are CNC-machined from 6AL4V grade 5 titanium, a material renowned for its strength-to-weight ratio and corrosion resistance. Their lightweight design reduces valve train inertia, which allows for higher RPM operation and quicker valve response. The combination of these materials and manufacturing precision ensures a durable, reliable, and high-performing valve train upgrade.
