[walawala]

Hi guys.

 

i'm totally a noob.

i've purchase a cusco lsd for my 2006 350z 6mt.the part number is LSD 251 L15.

but it's not compatible.i don't know why.

my vin is:JN1AZ34E56M100018

and the rear differential pumpkin part number is:383110c000.

please check the pic.the left is cusco,right is oem part.

 

 

now i was plan to purchase quaife lsd.

but don't know which is the right part.i don't want take the wrong part again.

and what is the difference between QDF11L&QDF13L.i've compare the cusco lsd.

they have the same dimensional.

 

looks like the QDF10L will fit with my oem pumpkin.

 

 

is there anyone can help me.

 

thks

Did you have open diff or vlsd? When you say fit is it the axels you mean? Ordered the wrong quaife for open (since peeps told me I had open without fins) turned out I had vlsd so had to buy new axels from the U.S. Feck all open diffs in Europe
