Atomic Barra Tool Steel Headstuds with OS Washers

Atomic Tool Steel Head Stud Kit – Ford Barra DOHC | 12mm Standard | Strongest in Class

Description:
The Ford Barra DOHC 4.0L is one of the most boost-hungry engines around — but factory head bolts simply can’t keep up when you start turning things up. Enter the Atomic Tool Steel Head Stud Kit (12mm Standard) — the strongest 12mm head stud kit on the market, engineered to clamp harder, hold longer, and resist failure where others don’t.

Manufactured from ultra high tensile H13 tool steel, these studs are built to survive extreme combustion pressure, high boost, and repeated heat cycles without stretching or losing clamping force. Ideal for XR6 and FG builds making anywhere from 400 to over 800 horsepower.
