The ARP VQ35 L19 Head Stud Kit for the 2003-2007 Infiniti G35 was 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.
The ARP VQ35 Main Stud Kit for the 2003-2007 Infiniti G35 is a must have for anyone looking to rebuild their VQ35DE motor.
This package is a MUST for anyone looking for 600+ Rwhp out of their VQ35 motor.
