ARP VQ35 HEAD & MAIN STUD KIT

Unlike the venerable Z32, the OEM head and main studs on the VQ35DE are not strong enough to handle the extra demands placed on them by a Forced Induction kit. There are many important reasons to use ARP main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block.

The studs are manufactured in ARP's own factory using the best materials, processes, designs and engineering. Every ARP main stud kit exceeds the most stringent aerospace specifications. All kits come complete with hardened parallel-ground washers and aerospace quality nuts. The studs are manufactured from 8740 chrome moly steel, heat-treated by ARP in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others. Don't settle for anything less than the best. On the basis of superior material, a special heat treating process, and advanced manufacturing technology, ARP Pro Series head studs are clearly the very finest on the market today.
