ARP VQ37 L19 Head Stud Kit - Nissan 370z/Infinti G37

The ARP VQ37 L19 Head Stud Kit for the Nissan 370z and Infiniti G37 were produced due to head lift issues at high WHP where additional clamping force is needed. While standard ARP studs can be torqued down to 65-70ft/lbs, these ARP made with 262,000psi tensile strength L19 steel can be torqued down to 90-95 ft/lbs easily, without breaking the stud. These are a direct drop in replacement, and require no special block modifications or machining.
