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.
Maximize the reliability of your engine assembly with these premium ARP flat washers. Featuring a 5/16 ID and a 13/16 OD, these chamfered washers are specifically designed for applications requiring a larger footprint to distribute clamping force effectively. Constructed from high-strength chromoly steel, they are built to handle the rigors of competitive racing.
The chamfered edge is a critical feature, allowing for proper seating against bolts that have a radius under the head, preventing the washer from 'riding up' and causing uneven torque readings. This ensures that your fasteners maintain consistent tension, which is vital for engine longevity and performance. The black oxide finish provides excellent corrosion resistance, ensuring your hardware looks as good as it performs. Whether you are performing a top-end rebuild or a full engine swap, these washers are an essential upgrade for any serious builder. Don't let inferior hardware compromise your hard work; rely on the proven strength of ARP products. Shop for all your high-performance engine fasteners and specialized components at GGCRACING.
