    Coming from the aerospace industry, Gary Holzapfel founded ARP (Automotive Racing Products) in the early 1970s to answer a major problem in motorsport: engine failures caused by bolts and studs that were not strong enough. At the time, no manufacturer was able to meet those needs. ARP now offers thousands of part numbers across several ranges and product types, such as head bolts, main bearing bolts and con rod bolts. Depending on the application, ARP offers several material ranges:

    • 8740 : a chrome-molybdenum steel with standard strength properties, perfectly suited to modified engines. This steel offers a tensile strength of between 1240 and 1447 N/mm2.
    • ARP2000 : stronger than 8740, the ARP2000 alloy withstands clamping and tensile loads of up to 1516 N/mm2. This range is widely used on circuit and drag cars and can be used with hydrogen.
    • L19 : a treated premium-grade steel offering tensile and fatigue strength well above the 8740 and ARP2000 ranges. Its tensile strength reaches up to 1792 N/mm2. This material is more prone to corrosion, so it must be kept oiled and away from moisture. Hydrogen is not recommended with this range.
    • CA625+ (Custom Age 625 Plus) : this "super alloy" offers far higher technical properties while resisting corrosion and oxidation. Its tensile strength reaches up to 1930 N/mm2.

    All ARP fasteners are designed and manufactured in the United States. Production starts with cold or hot forging, then a heat treatment (which varies with the range) is applied and shot peening removes any surface irregularity. Precision grinding then gives perfect concentricity before the thread is produced. Finally comes the finish, with a coating such as black chrome-molybdenum oxide or stainless steel polishing depending on the product range.

    Every kit is supplied with an assembly lubricant and an instruction sheet stating:

    • The installation steps
    • The thread of the bolts, studs and nuts
    • The tightening torque
    • The tightening procedure
