Atomic Head Stud Oversize Washer Kit – Ford Barra DOHC | 14.3mm Stud | 28mm OD | Hardened & Precision CNC
Description:
When pushing serious boost and cylinder pressure in high-power Barra builds, clamping force isn’t the only thing that matters — load distribution is critical. The Atomic Oversize Washer Kit is specifically designed for use with 14.3mm head studs, delivering maximum surface area to protect your cylinder head from crushing under extreme tension.
Each washer is precision-CNC and hardened, with an oversized 28mm outside diameter to fully cover the head boss and maintain even clamp pressure. Ideal for 1000+hp engines using large-diameter studs, this kit ensures your head gasket seal holds — without damaging the alloy casting beneath.
