Hey everyone, I'm just curious to see if there are many Rebel owners out there running the 3.21 rear ends. I purchased my rig off of the dealer lot and wound up with it as an added option. I wasn't wild about the idea at first because it sounded a little weak for a truck. I don't do any serious off-roading or towing too often so I figured I'd go with it. Now that I've had the truck for a little while I have to say that I'm happy with the rear. Pairing that ratio with the eight speed transmission seems to be a good combination. I don't think it sacrifices too much pulling power and it adds nicely to the gas mileage.
