ARP Chrome Moly Performance Washers

ARP Chrome Moly Performance Washers are hardened flat washers for high-load fastener applications in automotive, motorcycle, and powersports builds. They are also sold as chromoly hardened washers or performance flat washers. They are made to spread clamping load evenly under a nut or bolt head, which helps protect the mating surface and keeps fastener tension consistent.

Key Features:

• Chrome moly steel construction gives high strength and resists deformation under heavy clamping loads
• Heat-treated and hardened so the washer stays flat and doesn't crush or dish when torqued
• Black oxide finish adds corrosion resistance and a clean, uniform look
• Precision-made to match ARP fasteners and other performance hardware
• Load-spreading design reduces galling and surface damage on the clamped component

ARP is known for engineering and manufacturing high-strength fasteners in the USA for racing and high-performance use. These washers suit engine, drivetrain, suspension, and chassis assemblies where standard washers may not hold up. Pair them with ARP bolts, studs, and nuts for consistent, reliable torque and clamp load.
