Well I finished up my lift and new tires, see sig, and it is awesome. I still have 5th on the highway,my spedo is only off by about 4 mph, but the funny thing is that I am actually getting better gas mileage now. I have 104K on the truck and she is running awesome and is driving better than I could have imagined. I was thinking of re-gearing, but now I don't think it will be necessary. Take it easy guys.
