For all you Honda H22 builders out there, this BC0030 spring and titanium retainer kit is exactly what you need for race or limited street applications. Brian Crower created these specifically to fill the gap for high-quality performance components that are actually affordable and in stock. The titanium retainers are lightweight but super strong, reducing valve train mass which means you can safely rev higher. The springs are designed to handle aggressive cam profiles and high RPM situations without coil bind or fatigue. Everything is manufactured right here in the United States with strict quality control. Installation is pretty straightforward if you're familiar with engine work, and the flexibility of this dual setup means you can tune it for your specific needs - whether you're building a full race engine or a spirited street machine. The quality is immediately noticeable when you get your hands on these components - no rough edges or questionable tolerances. They're designed to work perfectly with other Brian Crower components too if you're doing a full build. Seriously, if you're pushing your H22 beyond stock limits, this spring and retainer kit provides that reliability and peace of mind you need. It's one of those foundational upgrades that protects your investment in other performance parts. The value is incredible compared to what you'd pay for similar quality from other brands. Your valve train will thank you!
