Supertech Titanium Valve Spring Retainers with PVD Coating Honda & Acura K-Series

Supertech titanium retainers with PVD coating are a serious valvetrain upgrade for high-RPM Honda and Acura builds. Made from military-certified titanium alloy and CNC machined for consistent fit, these high performance titanium retainers cut a noticeable amount of valvetrain weight while keeping the strength you need when you lean on the limiter. Less mass on the valvetrain means your K20A2, K20Z, or K24A engine can rev cleaner, hang onto valve control at high RPM, and stay happier when youre on cam for long pulls.

Each Supertech titanium retainer gets a PVD coating that hardens the surface and helps fight friction and wear. That matters when youre sitting at 8,000+ rpm in the heat, not just doing a couple dyno pulls. The PVD titanium retainers from Supertech hold up under track abuse, boosted setups, and long street miles without the faces chewing themselves up. Theyre built to work with high-lift cams, support up to 15mm max net valve lift, and keep things safe with an 18.5mm coil bind spec, so youve got real headroom for aggressive cam profiles.

This set (SKU: SPT-RET-K20A2-T2-16) includes 16 titanium engine retainers Supertech specs for a wide range of Honda and Acura applications. They drop in with compatible springs on K-series heads, so whether youre freshening a stock-style head or finishing a fully built bottom end, these titanium retainers CNC machined by Supertech give you the strength and weight savings you want for a reliable, high-RPM setup. We run Supertech titanium retainers Honda and Acura setups on our own cars, including K-swapped chassis and track-driven K24 builds.
