Alternator Belt Length For Alternators Of Different Amperages

[Z'06]

My '06 Tahoe 5.3 Flex-Fuel came from the factory with a 160-amp alternator (KW1). Question for the techs:

 

How much longer (in inches) is the alternator belt (the one between the crank pulley and the alternator) for a 160-amp KW1 alternator than for the two smaller size alternators (100-amp and 140-amp) that were commonly shipped on my body style truck? I know that aftermarket belts are sold by a product number identifying their length down to a tenth of an inch, so it's much appreciated if you can answer down to a tenth of inch. Thanks!

In Gates your belt is a K060930, the 6 is the # of ribs, the 930 is 93.0 inches. The other alternator belt is a K060923, so it is 92.3 inches. This number system goes for all Gates belts.
