Nissan RB20/RB25 Head Stud Kit 12 Point Nuts, 8740 Grade Material

12 Point Nuts, 8740 Grade Material

Aeroflow Performance head studs greatly improve your cylinder head-to-block sealing capabilities. This is important in engines with high power adders such as turbochargers, superchargers or nitrous. They can even be a great addition to a mildly modified build as insurance against gasket failure. All head studs provide a more accurate and consistent torque loading over traditional head bolts. These head studs are manufactured from aircraft quality 8740 high tensile strength chromoly steel and cold-forged to ensure molecular integrity within the stud. Meaning these studs are rated up to 190,000 psi making them stronger than Grade 8 and OEM fasteners. All kits come complete with 12-point nuts, hardened washers and Aeroflow anti-seize grease for an even load distribution and accurate torque readings.
