Message Hi folks,

I'm trying to finish up installing my Unorthodox Racing UD Pulley but recognized that it has a significantly different offset on the power steering pulley relative to OEM. This difference in offset is about 1/4" as seen in the below pictures. The difference between the inner and outer belts on the OEM pulley is 2.5" whereas the difference on the UR pulley is over 2.75". Along with the fact that the '95 uses a 3-rib PS belt whereas the UD pulley uses a 4-rib belt, this is a very significant difference over the short distance the belt travels -- you can see the divergence angle on the bottom picture with the ruler aligned to the UD pulley.

UR says that their UD pulleys are all the same from 90-96 but the other associated accessory pulleys are different between both the TT/NA and early/late model Zs.

I have a '95TT. Can someone please send me a picture or dimensions of the power steering pulley associated with UR for either the '95 or '96? I want to confirm that if I buy the right PS pulley from UR it will actually take out this offset and divergence. In my conversations with UR directly they have not given me the PS pulley dimensions or confidence that if I buy an extra PS pulley it'll match my car and/or UD pulley serial number.
