Upgrade the performance of your BMW S63 engine with 5150’s custom-designed Head Stud Kit, brought to you by ARP – the world leader in fastener technology.

This kit comes with all studs, nuts and washers, offering increased clamping force and enhanced head gasket sealing, which can prevent head gasket failure. This is particularly crucial for high-performance or turbocharged engines, as the increased cylinder pressure puts additional stress on the head gasket and bolts.

5150’s 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 S64 builds.

Description

Installation 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.

Please note: After initial assembly, it is necessary to allow the engine to complete a full heat cycle, then re-torque your head studs to spec. This means allowing the engine to warm up to its normal operating temperature, remain at operating temperature for several minutes to ensure each component is uniformly heated, then turned off and cooled completely to ambient temperature.
