hi,

I have been trying to search for the Diameters for the 2005 OEM 350Z crank pulley and UR underdrive crank pulley.

I could not find anywhere here or on the internet.. the Diameter of the UR Underdrive crank pulley.. and the Unorthodox website does not have it

I only found 2 different results for the Stock Diameter..

165mm's ( approx 6.5") and 5.75"

I beleive the 5.75" is the correct stock diameter..but still not sure.

I need to know the exact size of the stock Diameter and underdrive diameter crank pulley for 2005 350Z.. please


thanks

Tony.

 

I happen to have one (2005 OEM) laying here. Took a look with a tape measure.

 

I have a UR pulley in my back seat of my car, I will measure it at work tomorrow

 

wicked man thanks..

look at that so it is 6.5"

 

5 1/8th for ac, 4 7/8 for the rest
