Product Details

These washers feature a no-chamfer design and are engineered to provide consistent clamping force and load distribution when used with ARP fasteners.

Key Features:

  • Constructed from premium chrome moly steel for superior strength and durability
  • Parallel-ground surfaces ensure even load distribution across fastener contact area
  • Hardened construction resists deformation under high clamping loads
  • Black oxide finish provides corrosion resistance and professional appearance
  • No chamfer design for specific head bolt and stud applications
  • Precision-manufactured to tight tolerances for consistent performance

ARP washers are essential components for proper fastener installation, particularly in critical engine applications where precise clamping force is required. The parallel-ground surfaces ensure optimal contact between the fastener and component surface, while the hardened construction prevents crushing or deformation during torque application. Each washer is manufactured to exacting standards to ensure proper fitment and performance in demanding motorsports and performance applications.
