Product Details

ARP 254-6422 cylinder head fasteners deliver the strength and reliability required for high-performance engine builds. Engineered specifically for demanding applications, these fasteners provide superior clamping force to maintain head gasket integrity under extreme cylinder pressures and temperatures.

Key Features:

  • Forged in-house at ARP using premium aerospace-quality materials
  • Heat-treated using specialized vertical racks to ensure complete 360-degree penetration for uniform strength
  • Threads rolled after heat-treat to provide up to 10 times longer fatigue life compared to cut threads
  • Precision CNC-machined to exacting tolerances for consistent torque values and accurate stretch measurements
  • Engineered with optimized thread engagement and underhead radius for maximum reliability
  • Black oxide finish for corrosion resistance

Each ARP cylinder head fastener is manufactured to exceed OEM specifications, providing the extra margin of safety needed for modified engines, forced induction applications, and high-RPM operation. The superior material properties and precise manufacturing processes ensure consistent clamping loads and resistance to fatigue failure. ARP fasteners are the choice of professional engine builders and racers worldwide who demand absolute reliability from their engine components.
