8740 Chrome Moly Head Stud Kit

The ARP Main Stud Kit is engineered to provide enhanced durability and reliability for Nissan VQ35 engines. It addresses critical issues such as main cap walk and fretting, which can compromise engine integrity over time. By upgrading to these main studs, you also protect the threads in your engine block from potential damage during high-stress operation. The precision J-form threads are rolled after the heat-treatment process, resulting in fasteners that are significantly stronger than conventional threads. This meticulous manufacturing process ensures that every ARP main stud kit meets stringent aerospace specifications. Each kit is supplied with hardened, parallel-ground washers and aerospace-quality nuts, ensuring a secure and precise fit. Some applications may also include provisions for mounting windage trays, featuring specially designed standoff studs and serrated lock nuts to securely position and retain the tray.
