ARP Harmonic Damper Kit for 2003-2010 Ford 6.0L & 6.4L Power Stroke – Bolt & Washer
The ARP Harmonic Damper Kit delivers a high-strength bolt and washer to lock the harmonic damper on Ford F-Series Super Duty trucks and Excursion models powered by 6.0L or 6.4L Power Stroke diesel engines from 2003 to 2010. Crankshaft flex and twist generate massive kinetic energy that this kit absorbs while providing unyielding clamping force to prevent slippage. Built for diesel performance demands this fastener kit ensures long-term engine stability under high torque loads.
Key Features
- 190,000 PSI Tensile Strength: Delivers extreme clamping load to keep the harmonic damper firmly in place during high-rpm operation and heavy towing.
- 8740 Chrome Moly Construction: Heat-treated alloy resists fatigue and maintains integrity in hot oily engine environments.
- Black Oxide Finish: Provides corrosion protection for reliable performance in harsh underhood conditions.
- 1/4-Inch Thick Wide-Area Washer: Spreads clamping pressure evenly across the damper hub to avoid distortion and ensure precise alignment.
- Extra Tall 12-Point Bolt Head: Accepts deep impact sockets for secure torquing without stripping even under maximum effort.
Product Notes
- Inspect crankshaft nose threads for damage prior to installation.
- Use ARP thread lubricant or moly assembly lube on bolt for accurate torque.
- Packaged in ARP branded box for protection during shipping and storage.
Installation Notes
- Professional installation recommended.
- Torque bolt to 250 ft-lbs in two steps with angle tightening for proper stretch.
