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.
Engine assembly requires precision, and ARP 1/2 inch ID insert washers (200-8574) are the gold standard for ensuring your fasteners perform under stress. These insert washers are specifically designed to provide a flat, stable surface for bolt heads or nuts, ensuring even pressure distribution across the mating surface. This is critical for preventing gasket failure and maintaining consistent torque values in high-compression engines.
These insert washers are an essential upgrade for any high-performance build. By providing a hardened, smooth surface, they allow for more accurate torque readings, which is vital when working with aluminum cylinder heads or engine blocks. Don't risk your engine's integrity with inferior hardware; rely on the proven strength of ARP components. Whether you are building a street machine or a dedicated track car, these washers provide the peace of mind you need. Find all your essential engine hardware and performance components at GGCRACING.
