ARP Main Stud Kit VG30 Engines
Nissan VG30 ARP Main Studs come with 12-point nuts and high-quality, parallel ground washers. These main studs are manufactured by ARP from premium 8740 chrome moly steel and heat treated to 190,000 psi. They are thread rolled after the heat treating process, which vastly improves their fatigue tolerance compared to studs threaded before heat treatment.
A must for any high performance Nissan 300X Z31 engine. By installing an ARP main stud kit, you can eliminate main cap walk and fretting and protect cylinder block threads.
Now available from Whitehead Performance and in stock, the correct VG30E and VG30ET Main Stud Kit. This is not a reboxed SR20 main stud kit which does not work correctly on VG30 engines.
Each Kit Includes:
- Main Studs x8
- Washers x8
- Nuts x8
