What is the primary benefit of using titanium retainers?

Titanium retainers are significantly lighter than stock retainers. This reduction in mass at the top of the valve spring assembly helps decrease valve float, allowing the valvetrain to operate more accurately and reliably at higher engine speeds.

What kind of camshafts is this kit designed to work with?

This kit is intended for use with more aggressive camshaft profiles that require stronger valve springs to maintain proper valve control at higher RPMs. It's essential to ensure compatibility and check valve-to-piston clearance, especially with aftermarket camshafts.

Does this kit include everything needed for installation?

This kit specifically includes the single valve springs and titanium retainers. It does not include camshafts, seals, or other valvetrain components. Always refer to the manufacturer's installation guide for a complete list of recommended parts and procedures.

Product Details

Brian Crower is well-known for making high-performance engine components, and their BC0220 single spring and titanium retainer kit is a prime example of that dedication for Nissan VQ35DE engines. If you're looking to rebuild or upgrade the valvetrain on your Nissan or Infiniti, this kit offers a solid foundation for improved reliability and performance under demanding conditions. It's designed to handle higher RPMs and more aggressive camshaft profiles than stock springs can manage.

This kit includes precisely matched single valve springs and lightweight titanium retainers. The springs are made from a strong, durable material that resists fatigue, ensuring consistent valve control even at high engine speeds. The titanium retainers significantly reduce the mass at the valve spring's upper end, which helps to decrease valve float and allows the valvetrain to operate more smoothly and accurately. This reduction in mass is crucial for preventing valve-to-piston contact when you're pushing your engine hard.

This kit is a popular choice for enthusiasts working on a wide range of VQ35DE-powered vehicles. You'll find it commonly used in builds for models like the Nissan 350Z, Infiniti G35, and Nissan Altima, among many others. When installing, remember that this kit is designed to work with specific camshafts and requires careful attention to valve-to-piston clearance, especially if you're using an aftermarket camshaft. Always refer to the manufacturer's installation instructions for detailed guidance.
