You can pick up belts at Napa, Autozone, PepBoys, almost any car parts store. I personally recommend Goodyear Gatorback belts, although I am not sure who sells them online (anyone have a link).

As for size, I do not know, I do not have UDPs installed.

Dude I just bought one off of ebay too. Not bad for $70 shipped. Anyway post the link to the auction, if its the same thing I can give you the numbers for the belts.







I got the sonic if you got the boom.

I own a Unorthodox pulley...can somebody tell me the part number/ size for both the power steering and A/C belt?

here's what i used:
GATES K040320
GATES K050490

I got mine from www.rockauto.com because nobody around here carried them.

Just finished with mine.

Yes the belts are different. I got a Cosmo Racing UDP. Really nice, top notch machining...to quote my bro.

We are building a 2gnt DETAILED w/ all the problems v-faq and should be done soon. I don't have the belt part #'s on me it you still havn't figured it out email me personally and I'll send you them when I get home. The AC belt I can tell you is the same but you have to tighted the belt pulley above the AC. The other belt we got from CarQuest and I'll look up the # on their site and tell you what car and stuff it is for giving anyone easy access to them.

Timing belt just finished, new UDP, new Headers...man... I'm back in my 2g and it's feeling real nice.

Good day gents...

These are the part numbers I got for the belts:

GATES 4040355
GATES 4050510

Any of these correct? I got a GS.

I just printed instructions for installing an unorthodox pulley and towards the bottom it said:

alternator belt
Gates K040320(32.75 inches or 830 mm)

power steering and air conditioning belt
Gates K050490 (49.5 inches or 1255 mm)

Not sure what the gatorback belt equivalent is. I plan on getting a UPD when I get a timing belt. This has been asked a billion times but what can I really expect after this mod and is it worth it?

if yall searched... not talkin shit... there would be no reason for this thread...

hit up my site (been there for 4+years and very outdated) for the udp install...
