I know everyone always says that when you go with 35 tires, that you should upgrade to 4.56 at least to avoid damage to the transmission. OK well what happens when you have 4.56 gears and you bring the truck back to stock, including the wheels and tires?? Besides having a shit load of torque, anything else to worry about???

You will run higher than factory RPMs and have poor gas milage. The engine will be fine though, they can run a pretty high RPM no problem. Many trucks come with 4.10 from the factory and 31" tires. Put some small 33"s and you would be very similar.
