Heya everyone, I have an '03 Silverado with an STS equiped 6.0L + 4L80E + 9.5inch SF 3.73 geared rearend. My question is, I have a spare 11.5inch 14bolt (4.11 geared) that would bolt right up to my truck if I wanted too, and I tow a 5th wheel that weighs 10k dry and about 12-13k fully loaded. Will the 9.5inch hold up for the occasional recreational outing? Or should I just swap out the rearend to the 11.5inch one and be done with it?
Anyone know the towing capacity of the 9.5inch?

If you already have it I say do it just for the gearing. 9.5" is stock in your truck right? if so then just go off what the truck is rated for.
