4.30s f250
Ok, I decided to go from 3.73s to 4.30 in my 2004 f250 4x4cc 5.4 with stock tires. I needed the extra pulling power. Am i going to have to get my truck reprogramed for the different gears? Do I need a new speedo pickup? I am getting yukon gears, I am not to familer with gears. Are these a good brand?Anything else I should consider with the gear change? I know about the 500 mile breakend, and they are going to us amsoil oil in it. Should you change the oil after the breakend period?Thanks for the help.
