I haven't been able to find anything on this. I am planning on buying an underdriven crank pulley soon but I can get belts at work for a good price. Does anyone know what Goodyear size/part # is needed for underdriven crank pulleys? If not, what numbers of other brands are being used? I'd like to get the WRP pulley but I'm not sure it's even available yet.

 

Nobody on here with a pulley can post this? Come on! Help me out here!

 

Gates K040353 and K060445

we have the UR pullies, and belts in stock if interested

 

Sorry to bring this thread back... I am using the gates belt part #s above and my belts are squealing. I cant tighten them anymoee as my tensioner is maxed out. Are there alternative gatorback belt part #s? I bet those would get rid of the squeal.
