I'm looking into replacing my serpentine belt on my 2005 Tahoe 5.3L engine. I heard Goodyear's Gatorback belts are a good replacement. The OEM belt my Tahoe has is a 6KP2365, which I believe measures out to 93.1 inches in effective length. Gatorbacks do not come in 6KP2365. The closest they have is a 6KP2360, which is 93 inches in effective length. They also have one slightly longer, 6KP2375, which is 93.5 inches in effective length.
Does 1/10th of an inch shorter on belt make a difference (i.e. stress on tensioner, pulley damage, etc) if I were to go with Gatorbacks 6KP2360? What about going with the 6KP2375, which would be 4/10th inches longer? Or, am I better off buying the OEM? Trying to save myself some money here.....OEM replacement at dealership costs an arm and a leg.

Sounds good fellas. Thanks for the responses. Going with the gatorback belt will save me $45. Dealer wants $74 for the belt....ouch! My current belt has 81,000 miles on it and still looks good; however, the ac belt is cracking. Figured, I'd change serpentine belt (preventative maintenance) since I have to remove it to replace the ac belt.
