All of that stuff comes with the gear (or at least it did when I purchased from Z1). The only thing I needed was shims but you wont really know which ones you need (theres like 12 different ones) until the installer measures with a dialer for lashback. Let the shop deal with that headache lol

Did you see my post a few back? lol I did the same thing already.

IMPORTANT NOTE FOR 7AT GEAR SWAP WITH QUAIFE DIFFS

YOU NEED TO GET THE QUAIFE DIFF FOR A MANUAL TRANSMISSION OR YOU WILL NOT BE ABLE TO INSTALL THE 4.08 GEAR.

THE QUAIFE DIFF FOR AUTOMATIC TRANSMISSION WILL NOT WORK WITH 4.08s

Thanks for the advice. Def not doing it myself and didn't want to buy a sport manual pumpkin if it isn't necessary. Sounds like you're saying that if I have the correct install kit (bearings, seals, washers, shims, etc.), the manual quaife lsd and 4.08 would fit the open diff on a base 7AT. Is that right?

you will want to get a quaife for a manual , base car and whatever gear set you choose (except 3.333) and then you can use your 7at non-sport case and stub shafts with a lot of shimming at that point i would take it to a shop and let them buy everything else you will need

Review:

The Quaife diff + 4.08 gears with whiteline bushings and redline gear oil = awesome :)

I've got a 38301-EH53D for sale.

I have a 09 370Z auto with VLSD. I want to have 4.08 final with an aftermarket LSD.

Do I need to purchase a manual non-VLSD pumpkin from a base model or a manual VLSD pumpkin from sport package to make this work?

Both will work, I'd get the Sport just to be safe. If you get non sport you'll need to order the aftermarket LSD with stub axles I believe. Someone correct me if I'm wrong please.

your fuel milage is terrible! i get 25+ with my 370/7at & drive aggressive at times.

i may be reviving dead thread, but some of the terms used in these kind of threads are unclear to me. when people talk about swapping pumpkins(differentials?)are they simply referring to carrier assembly, or are there other parts necessary? can i simply swap my base auto carrier with the mt vlsd carrier and then install the gears

on the a/t model's...not many gear ratio's to choose from,,,the "pumpkin"is the center section...unbolt c/v axles,drive shaft,2 speed sensor's,2 mounting bolts & 1 nut from stud through crossmember.
drop it down & you can buy a second one & have it built.
pumpkin's from manual trans. Z's offer gear ratio's from 3.54....up to 4.36:1.
you may have to swap one of the stub shaft's for it to bolt in.
Newer Z's...15' & up...came with a 3.69:1 in some A/T models & 3.92:1 in manual Nismo models.
I swapped the open carrier in my 11' A/T & added a Quaife ATB helical locker....but no lower gears were available at that time...haven't checked in a while.

seems good for me because my car have drone at cruising RPM

sorry to kinda resurrect this thread, but do i need to buy a manual pumpkin/carrier, or can i just get the diff itself and swap that into my sport auto? because im trying to do the 4.08 FD but im a little confused as to what i need exactly.
