Atomic Billet Crank Sprocket – Ford Barra DOHC | Heat Treated & Case Hardened | Precision Fit
Description:
The factory crankshaft sprocket in Ford Barra DOHC 6-cylinder engines is prone to wear, noise, and movement under the extreme loads generated by high RPM, big boost, and stiffer valve springs. The Atomic Billet Crank Sprocket solves these issues with a case-hardened, heat-treated steel construction and tight manufacturing tolerances for precise fitment and maximum durability.
Whether you’re building a street car or a 1500hp race engine, this sprocket ensures accurate cam timing, reduced vibration, and long-term reliability — and is a key component in every Atomic timing chain kit.
