Product Description

The Brian Crower BC0040 Dual Valve Spring and Titanium Retainer Kit is engineered for high-performance applications in Honda K20A, K20Z, F20C, and F22C engines. This kit is designed to support cam lifts up to 0.550", making it suitable for high RPM and high-lift camshaft setups.

The dual valve springs are wound from high-grade chrome silicone alloy by PAC Racing, ensuring consistent spring pressures and durability at elevated RPMs. The CNC-machined 6AL-4V titanium retainers reduce weight, allowing for higher RPM potential and improved valve control. The kit also includes steel spring seats (BC2904), facilitating direct installation without the need for machining in compatible heads.

With a free spring length of 2.025" and a coil bind height of 1.030", this kit provides optimal preload and prevents spring bind at high RPMs. The BC0040 kit is ideal for enthusiasts seeking to maximize their engine's performance potential without compromising reliability.
