When building a high-performance KA24E engine for your 1989–1990 Nissan 240SX, you need hardware that can handle the pressure—literally. That’s why ARP Pro Series Head Studs are the first choice among top engine builders and racers around the world. Whether you're running a naturally aspirated setup or pushing serious boost, these head studs are engineered to provide superior clamping force, ensuring your cylinder head stays sealed tightly to the block under extreme loads. They eliminate the common issues caused by head lift and gasket failure, especially in high-horsepower or turbocharged applications.
Each stud in this ARP kit is made from premium-grade 8740 chromoly steel, which is heat-treated to an incredible 200,000 psi tensile strength. After heat-treatment, the studs are centerless ground for perfect concentricity, ensuring easy and accurate installation every time. Unlike lower-quality alternatives, ARP studs are thread-rolled after heat-treatment, which improves fatigue strength by up to 1000%—making them exceptionally durable and reliable in the harshest conditions. This attention to detail ensures consistent torque readings, uniform clamping force, and long-term reliability for your engine build. ARP studs are the gold standard in engine fasteners and are stamped with the ARP logo as a guarantee of quality and performance.
