ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Sometimes you only need one more piece to finish the job. This single Auto Racing Products 5/16 ID x .550 OD flat washer offers the same professional-grade quality as our larger sets. Precision-machined from high-strength chromoly steel, this washer is designed to provide the clamping force and durability required for high-performance racing engines.
Whether you lost a washer during assembly or are doing a custom project that requires a specific count, this single unit ensures you don't have to buy more than you need. The chromoly construction is significantly stronger than standard hardware-store washers, ensuring that your engine components are protected from vibration, heat, and torque-induced fatigue. The black oxide finish provides excellent resistance to corrosion, keeping your engine bay looking clean and professional. When building a high-performance engine, every component plays a role in overall reliability. Don't settle for inferior hardware; use the best in the industry to ensure your build is ready for the track. For all your individual fastener needs and complete performance kits, look no further than GGCRACING.
