It was a 5.3 and I never did research the rear end gear ratio. Truck went like a raped ape when not towing. But put a trailer behind it and it was not a good day. I towed that trailer twice from Massachusetts to Montana and back. The last trip I got home on a Monday and Wednesday I had a Dodge Diesel!
This Diesel will tow my 5 place , 10,000 motorcycle trailer like it isn't there. It has NEVER downshifted going up any hill. And towing I'm getting 15mpg. I have to use cruise control to stay under 75mph. Nothing like a diesel for towing.
Must have been something wrong with my 5.3 or my expectations were simply too high.
