There are many important reasons for using ARP Stud Kits for your 1.6 or 1.8 Mazda MX-5, including securing the cylinder head securely and protecting the threads in your engine block. Each ARP headed bolt kit exceeds the most stringent aerospace specifications. All kits are supplied with hardened, parallel ground discs and quality grade aerospace grade nuts. Bolts are made from 8740 chrome moly steel, heat treated in house to 190,000 psi tensile strength, and fitted with precision J-shape threads that are rolled after the heat treatment to create a fastener that has a 1000% stronger thread than others. The ARP Pro Series kits are also available with 12-neck nuts.
Of course, we also use the product ourselves in our racing cars and also in the private cars of our employees in order to be able to offer you the best possible service. We also had the opportunity to extensively test the product itself to see if the product meets our needs. We recommend these studs for use up to 1.1 bar boost pressure.
