Not it's not I pretty sure my Hoe has 3.42 gears but also has the tow package, but only rated to tow 7500lbs, sure yours don't have 4.10 gears? I found this about 2001 Suburbans: For a 1500 2wd w/ 3.73 gearing-7800lbs, w/ 4.10 gears-8800lbs. If it is a 4wd w/ 3.73 gears-7600lbs, 4wd w/ 4.10 gears-8600lbs. Vehicle gearing is indicated by vehicle RPO codes, which are on a sticker in the glove box. It is a sticker with many 3 digit codes. If you see a GT4 you have 3.73 gears. If you see a GT5 you have 4.10 gears.
