When it comes to high-RPM performance, every gram matters. The Atomic Titanium Retainer Set for Ford Barra DOHC 6-cylinder engines is designed to significantly reduce valvetrain mass, allowing your engine to rev harder, faster, and more reliably — all while improving valve control under extreme boost and high RPM.
CNC-machined from premium aerospace-grade titanium, these retainers are ultra-light yet incredibly strong, making them ideal for engines with aftermarket camshafts, high-lift profiles, stiffer valve springs, or those chasing big RPM targets. Used in every top-tier Atomic engine build, this is the go-to upgrade for serious Barra heads.
