I just got some pullies for my 5.3 and I was curious to know if anybody knows where I can find out what size belts I need? Any help is appreciated. Thanks.

 

That really is a stupid pulley question,J/K. The part number for the accessory belt with crank pulley only is Gates K060895, AC belt Gates K040345. With crank and alternator pulley, the accessory belt is Gates K060900, and the A/C belt is same as above.

 

What Do You guys suggest. Using the UD pulley only or using UD pulley and Alt pulley? Thanks for any help.

 

When and where did you get them? I've been trying to find just a asp crank pulley and can't find one.

 

I got them 2 months ago but I got them directly from ASP. I don't know why I ordered them direct becaues it cost me more money (arround $40.00 more). But you can order them from them. I have heard that a good place to go and get them is TBYRNE.

 

Does Anybody have any suggestions?

 

Is it the OD alt pulley? It depends on what other electrical components you are running. Stereo/amps, extra lights, DVD, e-fan, etc. If you are using a lot of volts/amps then go with the OD alt pulley. Otherwise just use the UD pulley.
