ARP heavy duty studs are made of high strength and heat treated 8740 chrome-moly forged steel and so they are ideal for use in racing engines. Due to advanced manufacturing processes ARP studs reach highest strength and stability. Tensile strength of 200.000 psi (13,8t/cm²). Absolutely perfectly round and straight studs for a first-class assembly. All kits come with ARP hardened washers and high quality nuts. Harder, more durable, stable, and processed better than any OEM products. 10 times stronger threads than the competetive products by thread cut after curing. Highest ARP quality product for professional use. Fully reusable. If the washers do not fit in combination with the support plates, ARP recommends removing the washers and only using the support plates. In this way, the protection / baffle plate can also be refitted.
