i'm am getting ready to put the UD Pulleys on and i noticed that the crank pulley is smaller than the stock one, am i going to have to get a smaller belt? or am i able to use the stock one?

If you have the full kit with the water pump pulley and alt pulley than no new belt is needed. If you just got the crank damper then it is possible you will need a smaller belt.

Your stock belt should be fine. Now go put them pullies on and tell us how you like em!

Depending on how small of a pulley you're going with, you may need a new belt for everything to fit snug.

Aeron.. he shouldnt need a new pulley.. it's not like the s/c pulleys...

The UDP kit you have should actually make up the size in other places (i know my UDP kit did)... but be careful if you're installing the crank pulley... make sure you take your time with it, you don't wanna screw anything up...

Should being the key word, most aftermarket companies are not that thorough when putting their kits together.

I have never seen a kit that didn't.

Might want to throw a fresh belt in there anyway while you there and taking it off.

don't get rid of your stock pullies too quickly. If you ever want to S/C your car you'll want your stock pullies.
