this is probably thw most rediculous question youve seen in a while but looking under the hood of my 05 rcsb 4.8 the fan looks like a efan what is the difference between stock and aftermarket?

What are your opinions on a good set of pullys to get for my truck?


And would putting in a stall converter at the same time as i put in my shift kit save any money on labor?

 

Never seen aftermarket but they probably have some type of mfg marking and the GM's don't.
ASP underdrive pulleys are the ones everyone likes.
Don't think so, to install the converter the trans has to come down.

 

What he said.

 

perfect thanks guys

 

you should have efans stock

05 and newer trucks came with them

 

so would there be an upgrade is stock good enough

 

stock is good enough

 

Looking around for the asp underdrive pulleys cant seem to find any for 05 only the 04 and older anyone know of any websites to get them from or should i just call asp directly
