Atomic Harmonic Balancer Bolt Kit – Ford Barra 4.0L DOHC | High-Tensile + Nord-Lock Washer
Description:
When you're pushing big boost and revving your Ford Barra 4.0L DOHC hard, the harmonic balancer is under stress. The factory crank bolt just isn't up to the job — and if it backs out, the results can be catastrophic.
The Atomic Harmonic Balancer Bolt Kit is the essential upgrade to lock your balancer in place and protect your crank, oil pump, and timing gear from failure. This kit includes a high-tensile, deep-thread crank bolt and a genuine Nord-Lock washer — a dual-wedge locking system used in motorsport and aerospace that won’t loosen under vibration or torsional load.
