you just provided the torque spec

My best guess is BOLT **1B6-8501A

Part Detail

FYI, the SEC # information at the top of the drawing is the corresponding parts catalog page(s).

i searched in FAST and came up with nothing

it's also bigger than p/n 081B6-8501A

Here,Knock yourselves out playing the Part # game.

Call these guys if you can't find what you're looking for. I'm sure they can help.Good luck.

I looked over FAST using a CV36 instead of the Z34, just in case FAST didn't include the part on the Z34. When you stated its bigger than 081B6-8501A, I assume you have it off the car and have physically compared them. What are the dimensions of the bolt? I can't believe Nissan FAST don't tell hardware dimensions-very weak and lame on Nissan's part.
Here's what I came up with, in order of preference:
54459-1EA0A: '09'- Z34 stay tunnel assy bolt
08157-0602F: '08-'10 G37 stay rear suspension bolt
081A7-0601A: '11 G37 stay rear suspension bolt
081A7-0201A: '12 G37 stay rear suspension bolt

op - let's not.

Now why didn't i think of using the g37 as a reference :icon14:

I didn't completely remove the bolt since the tunnel stay (pc 3 in the service manual pic) was in the way, but it uses a 14 mm socket where as 081B6-8501A uses a 12 mm socket so i figured 081B6-8501A is smaller.

54459-1EA0A is also uses a 12 mm socket.

Thanks for the info. I'll check with the nissan/infinity dealer to see if they have the first two g37 bolts and see what's the difference.

Thanks for the help :tup:
