My rear diff came from a 06 G35 automatic, you can use a G35/350 doesn't matter as long as its from a auto. The automatic cars are the only ones that come with a 3.3 final drive. This is a direct swap you take out your diff and swap in the other one.






I think it has to do with the speed being off for cruise to work in 6 gear.


If you have a OSG LSD already and it's for a manual car it wont work in the automatic diff. The pumpkin housing are the same it's the internals that are different ring and pinion.

If anyone wants a rear diff I spoke to my friend that works at the junk yard where I got my from and you could order one and have it shipped.

PM me for details in your interested .

I wanna take you up on this so bad. But have no desire to try and sell this LSD and find another one..

Yeah. I think 3.3 is going to be too low for me. I do use cruise in 6th. I'm lazy on road trips!

You can always keep your LSD and get 3.53 diff it will fit that.





I can see this being a problem ,but I wouldn't really switch to the 3.3 on stock block unless I was pushing at least 525whp. I think anything lower than that its a waste my low boost spring pressure is 600whp I need it .

That's a good point. For Phase I, I am only shooting for 500 WHP. Where would one get a 3.53 gearset? Does anyone make a plug-n-play diff for the Z with different ratios?

No one makes plug and play diff with different ratios where stuck with the ones that are available.

You can get the 3.53 from my contact from the junk yard over here in my area

check you Pm.

Thanks! What does the 3.53 come off of?

It comes from a 350z/G35 manual transmission 03-08 anyone will work direct swap .
