Atomic Harmonic Balancer Bolt Kit – Ford Barra 4.0L DOHC

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.


Key Features:

✅ Suits all Ford Barra DOHC 4.0L engines
High-tensile crank bolt – extended thread for maximum clamping force
✅ Includes Nord-Lock vibration-proof washer system
✅ Prevents balancer walk, crank key damage & oil pump misalignment
✅ Designed for boosted, high-RPM & competition applications
✅ Trusted in Atomic 1000+hp builds across Australia


🔧 Why You Need It:

✔️ Factory bolts can loosen or stretch under extreme RPM and torque
✔️ Nord-Lock washer system locks into place under load – won’t back off
✔️ Essential for engines with large turbos, high stall converters, or nitrous
✔️ Protects your bottom end — affordable insurance for high-power builds
✔️ Direct-fit upgrade with no modifications required


Whether you’re daily driving your turbo Barra or chasing 1000+hp at the track, the Atomic Harmonic Balancer Bolt Kit ensures your engine stays locked together — no matter what you throw at it.
