The ARP Pro Series Cylinder Head Studs are the gold standard for high-performance engine builds, particularly for RB engine enthusiasts. These head studs are made from premium 8740 chrome moly steel, heat-treated to a remarkable 190,000–200,000 psi to provide superior strength and durability. The studs undergo a rigorous manufacturing process, starting with cold-forging to ensure molecular integrity, followed by heat treatment and centerless grinding to guarantee perfect concentricity. The thread rolling process after heat treatment improves fatigue strength, making them significantly stronger than those that are threaded beforehand. This attention to detail ensures these studs can handle high-boost, high-performance setups without fail.
Designed for the RB20DET, RB25DET, RB25DET NEO, and RB30 dual cam conversion, these head studs are a must-have for any serious engine builder. ARP’s high-quality parallel-ground washers allow for more accurate torque readings and better load distribution, while the 12-point or hex nuts provide reliable and even clamping force to prevent cylinder head lifting. With ARP’s commitment to excellence, you can trust that these studs will keep your engine sealed tight under extreme pressure, preventing blown gaskets and ensuring a long, reliable engine life. Whether you’re rebuilding an older RB engine or pushing your build to the limits, these ARP head studs are a top-tier choice for any high-performance application.
