ARP uses different materials and processes to manufacture its products, depending on the intended applications. Here is a summary:

• ARP 8740 (Chromoly) : This is the material with an unbeatable price/quality ratio. It currently offers excellent results and performance for most so-called "racing" applications. Thanks to its various surface treatments and heat treatments used by ARP during design and manufacturing, this material has a resistance of around 200,000 psi.
• ARP 2000 : This high-performance steel alloy has been specially designed to offer increased resistance compared to the famous 8740. It can withstand pressure peaks of up to 220,000 psi. The ARP 2000 is often used for engines in very intensive disciplines such as circuit racing, drag racing or drifting.
• L19 : This so-called "premium" category steel has undergone successive treatments which give it a much higher resistance than the ARP 2000 (260,000 psi). L19 steel solutions are often used in very extreme applications on the circuit and in dragsters and on very high-performance engines. However, like the ARP 2000 and the 8740, L19 is particularly sensitive to corrosion and therefore requires somewhat special precautions for use.
• Custom Age : This new alloy designed by ARP has exceptional strength properties (up to 280,000 psi tensile strength). The Custom Age series is completely stainless, this alloy is exclusive and specific to ARP . To date, it is THE best solution offered and existing on the market.
