The ARP 400-8539 is a high-performance washer set designed for demanding engine applications. These premium washers feature an inside diameter chamfer and are constructed from chrome moly steel for exceptional strength and durability.

Key Features:

  • Chrome moly steel construction for superior strength
  • Precision parallel-ground surfaces ensure consistent clamping force
  • Heat-treated and hardened for maximum durability
