Upgrade the performance of your BMW N63 engine with our ARP Head Stud Kits, specifically designed for the turbocharged V-8 N63 engine. As you increase the power output of your engine beyond its factory specifications, the head and block may start to separate, causing factory bolts to stretch and fail. Our ARP Head Studs are designed to be stronger than factory bolts, ensuring your race engine stays together even under extreme conditions. Our Custom Age 625+ kit is made from a material with a tensile strength of 260 ksi, substantially higher than the 190 ksi of the ARP 2000 head stud. It's an ideal choice for individuals who want to push the limits of their N63 builds.

For engine builders pushing the absolute limits of high-performance engineering, the ARP Custom Age 625+ Cylinder Head Stud Kit represents the pinnacle of fastening technology. While standard aircraft-quality steels and even the renowned ARP2000 alloy are impressive, the proprietary Custom Age 625+ super-alloy provides a massive leap in capability by increasing tensile strength by an additional 40,000 to 60,000 psi. This specialized hardware is engineered specifically for ultra-high-boost applications, offering superior fatigue resistance and the unique ability to maintain its structural integrity under extreme temperatures that would cause lesser materials to weaken.

This ARP head stud Kit is designed for the BMW S14 B20, S14B23, S14B25, S14B27 engines found in the E30 M3. Installing ARP head studs can provide several benefits, including increased clamping force, improved head gasket sealing, and greater overall engine strength. This is especially important in high-performance and racing applications where the engine is subjected to increased stress and higher temperatures. Before installing ARP head studs, it is important to properly clean and prepare the engine block and cylinder head mating surfaces. It is also recommended to use ARP Ultra-Torque Fastener Assembly Lubricant during installation to ensure proper torque and clamping force. Instructions: 1. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with ARP Thread Chaser. 2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit, length and dimension. 3. If the cylinder head studs protrude into a water jacket, lubricate the block threads of the studs with ARP THREAD SEALER. 4. Screw studs into the block “HAND TIGHT ONLY”. 5. Install the cylinder head(s) and check for binding or misalignment. 6. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Then install the washers and the nuts onto the studs and tighten them hand tight. ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil or other low quality lubricants are used.
