Different materials and processes are used by ARP to manufacture their products depending on the intended applications. Here is a recap:

• ARP 8740 (Chromoly) : This is the material with the unbeatable quality/price ratio. To date, it offers excellent results and performance for most so-called "racing" applications. Thanks to its various surface treatments and heat treatments used by ARP during the design and manufacture, this material is at a resistance of around 200,000 psi.
• ARP 2000 : This high-performance steel alloy has been specially designed to offer you 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 being in very intensive disciplines such as circuit or drag racing or drifting.
• L19 : This so-called "premium" steel has undergone successive treatments which gives it a much higher resistance than ARP 2000 (260,000 psi). L19 steel solutions are often installed in very extreme applications on circuits and in dragsters and on very high performance engines. However, like the ARP 2000 and the 8740, the L19 is particularly sensitive to corrosion and therefore requires somewhat special precautions for use.
• Custom Age : This new alloy, designed by ARP , has extraordinary strength properties (up to 280,000 psi tensile strength). The Custome Age series is Completely Stainless, this alloy is exclusive and unique to ARP . To date, it is THE best solution offered and existing on the market.
