The ARP Main Stud Kit for the 2JZ fits both the twin turbo and base model engines, perfect for any amount of horsepower your build will take on. ARP uses top-notch 8740 alloy, which is way better than what's typically used in aircraft. They heat-treat each stud meticulously to 200,000 psi, ensuring they're super strong. This process ensures the studs can handle high-performance engines' intense heat and pressure, unlike cheaper alternatives.

After heat-treating, ARP grinds each stud precisely to make sure it's perfectly straight. Cheaper studs skip this step, resulting in uneven parts that can cause alignment issues. With ARP studs, everything fits together smoothly, reducing the risk of leaks or damage.

ARP also rolls the threads after heat-treating, making the studs much stronger than those threaded before. This extra step ensures the studs can handle the constant stress of engine operation without failing. With ARP, you're getting top-of-the-line quality that's unmatched by other brands.

So, if you want the best for your engine, look for ARP stamped on each stud. It's your guarantee of quality and reliability.
