Construction & Design

The ARP Washer Kits are constructed from high-grade chromoly steel, known for its exceptional strength-to-weight ratio and resistance to fatigue. The washers are precision-machined to tight tolerances, ensuring a perfect fit and uniform load distribution. Their flat, smooth surfaces minimize the risk of surface damage and facilitate proper seating during assembly. The 0.120-inch thickness provides a reliable spacer or load-bearing surface without adding unnecessary bulk, making them suitable for a wide range of automotive applications.

Performance & Use

While these washers are not designed for high-stress engine internals such as cylinder head or main bearing applications, they excel in general fastening and accessory mounting tasks. Their chromoly construction ensures longevity and resistance to corrosion, especially when used in conjunction with proper hardware and torque specifications. These washers help support secure, stable connections, reducing the risk of loosening or component failure over time.

Installation & Fitment

Installing the ARP Washer Kits is straightforward and requires no special tools beyond standard hand tools. Simply place the washer between the fastener and the surface being secured, ensuring proper alignment and seating. No cutting, drilling, or special tuning is necessary. These washers are designed to fit standard 7/16" fasteners and are compatible with a wide range of automotive applications, making them a versatile choice for your build or repair project.

• Ensure the washer is properly seated before tightening.
• Use the appropriate torque specifications for your fasteners to prevent over-tightening.
• Inspect washers periodically for signs of wear or deformation during maintenance.
