LOOKING FOR PART NUMBER FOR LS1 SWAP SERPENTINE BELT WITH ASP CRANK PULLEY

GOES AROUND CRANK,WATER PUMP,ALTERNATOR,POWER STEERING PUMP AND TENSIONER PULLEY

ANY SUGGESTIONS? PART NUMBERS?

 

It's the stock ls1 belt. The ac pump runs off a separate, short belt behind the main accessory drive. GM made it easy for us non ac guys.

 

DO YOU HAVE A PART NUMBER

 

LOOK IT UP ON ROCKAUTO.

 

I have a aftermarket crank pulley(ASP) What belt to use?

 

Check with vendors that have the ASP pulley. I know thunderracing used to sell them, and they had the belts listed right below it. Or try ASP's site?

 

Or measure it. You'll find the PNs for a given application will vary from vendor to vendor since it is subjective from the tensioners throw. FYI, you want to measure with the tension at 1/2 throw, this usually takes a second person

Belt mfrs put the belt specs into the PN for quick identification. Parts store monkeys usually dont know how to read them so dont ask them for a xx" belt
