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.
✅ Key Features:
✅ Suits all Ford Barra DOHC 4.0L 6-cylinder engines ✅ Set of 24 lightweight titanium retainers – full engine set ✅ CNC-machined from aerospace-grade titanium ✅ Reduces valvetrain mass – improves RPM response and control ✅ Ideal for high-lift cams, heavy springs, and performance builds ✅ Recommended for use with HD roller rockers and 1–2mm oversize valves ✅ Trusted in Atomic-built heads making 1000–1800+hp
🛠️ Why Use Titanium Retainers?
✔️ Less mass = better valve tracking and less spring stress at high RPM ✔️ Allows more stable operation at extended engine speeds ✔️ Helps prevent valve float and lifter instability ✔️ Perfect match for performance valve springs and cams ✔️ Precision fitment for stock or Atomic performance valves
📦 What’s Included:
Set of 24 titanium valve spring retainers – full coverage for all 6 cylinders
