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

• 8740: This is a chrome-molybdenum steel with standard strength properties fully suited to tuned engines. This steel offers a tensile strength of between 1240 and 1447 N/mm2.

• ARP2000: More resistant than 8740, the ARP2000 alloy can withstand clamping/tensile loads of up to 1516 N/mm2. This range of bolts is frequently used on track and drag cars and can be used with hydrogen.

• L19: This is a higher grade treated steel offering tensile and fatigue strength properties significantly higher than the 8740 and ARP2000 ranges. Its tensile strength can reach up to 1792 N/mm2. This material is more sensitive to corrosion and must therefore remain oiled and not exposed to moisture. It is not recommended to use hydrogen with this range.

• CA625+ (Custom Age 625 Plus): This "super-alloy" has significantly superior technical properties while being resistant to corrosion and oxidation. Its tensile strength can reach up to 1930 N/mm2.

All ARP hardware is designed and manufactured in the United States. Manufacturing of ARP hardware begins with cold or hot forging, then heat treatment (different depending on the range) is applied, followed by shot peening to remove irregularities. Next comes precision grinding to achieve perfect concentricity, then the thread is cut. Finally comes the finishing stage, during which a coating is applied such as black chrome-molybdenum oxide or stainless steel polishing, depending on the product range.

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