Hi,

I have a question, i need to change my differentiel. Actually i have this ref : 3831100048. A man offer me a 3831100047 from a 2004 350z. What is the difference please ?

Thanks

 

Cool story, what is your car and what is the car that diff came from? Base model dudes are different than touring model dudes and 6 speed sides are diff than auto diffs. They should all bolt up though.

 

Hi, its a pack with brembo kit and 6 manual speed. The 2 diff can be install but it exist different technologies of diff and i want To know which are they. I called nissan but say cant answer me....

 

You could use the VIN decoder on here and figure out which Z33 model you have. It may be a track model and if so, has a VLSD (viscous limited slip differential). The other diff that came standard on USDM 350Zs was an open diff, which offers no lockup under load. Maybe the better question to ask is why do you need to replace the entire differential?.

 

Ok, i need one because the old owner has weld it... I know what type of diff i have but i want To know if the man who offer me have the same.... because it end by 47 and my 48... his diff come from a 2004 280hp z and mine 300hp 2006... as my opinion it is the same but i cant be sure...

 

Say what!!?? We need more detail here!

 

My z :

2006
300hp
Uk
Brembo
Rays
Pack


Diff come from :

2004
280hp
France
Brembo
Rays
Pack

His réf number end by 47 and mine by 48.
That s all..

 

You will be good 2 go. His should have the factory vlsd. The only automatic and base model diffs are different. Base model has open diffs, and auto has different gearing.

If you want you could go to Z1 look up their differential package and download the pdf file about all the different configurations.
