As much as I'd like to believe that post....I'm not sure. I thought the 03's were going to come with BFG's and not Goodyear F1's...but then I could just be losing my feeble mind....:??:
I read where supposedly they replaced the "Blower Pulley". I've also read that it is better to replace the lower pulley that runs off the crank instead of the blower pulley. Replacing the blower pulley could damage the blower or reduce it's life and the smaller pulley could cause belt slippage.
It would be better to hear that they replaced the lower pulley...I'm still interested in how the aftermarket people will provide a solution for increasing the size of the '03s lower pulley. Since there is an idler pulley in very close proximity to it and also has the altenator running off the same belt.
