Product Details

The ARP 135-6401 cylinder head fasteners are precision-engineered studs designed to provide superior clamping force and reliability in high-performance engine applications. Manufactured from ARP's premium 8740 chrome moly alloy steel, these fasteners deliver exceptional strength and fatigue resistance far beyond OEM specifications.

Key Features:

  • Forged in-house at ARP using premium 8740 chrome moly steel for tensile strengths between 180,000 and 210,000 psi
  • Heat-treated using specialized vertical racks to ensure complete 360-degree heat penetration
  • Threads rolled after heat-treatment to provide up to 10 times longer fatigue strength compared to cut threads
  • Precision CNC-machined to exacting tolerances for consistent, reliable performance
  • Black oxide finish for corrosion resistance and professional appearance
  • Complete kit includes all necessary fasteners for proper installation

ARP 8740 Chrome Moly Advantage:

  • Excellent fatigue properties for racing and high-performance street applications
  • Superior grain flow structure from specialized forging process
  • Consistent clamping loads prevent head gasket failure and cylinder head warping
  • Reduced risk of stress corrosion when properly installed and maintained

ARP fasteners are the gold standard in performance engine building, trusted by professional engine builders and racers worldwide. Each fastener is proudly stamped with the ARP name as your assurance of quality and precision manufacturing. These head studs provide the reliability and strength needed for turbocharged, supercharged, nitrous, and naturally aspirated high-performance engines.

Great customer service and product pricing! Received tracking number very quickly and will recommend to anyone!!!!<br><br>Thanks

For the over-the-winter garage storage of my 911, the Rail Ramps Flatstopper product has eliminated the need to move the car over the winter in order to avoid the tires developing flat spots.

Fast Shipping. Good packaging. Very good pricing. Will shop from again.
