I have a 96 F Super Duty with a 10 lug Dana 80 rear on it. Its a 5.13 so my cruising speed is stuck at about 60 mph without the motor revving past about 2500 rpm. Would it be better to swap the ring and pinion for a 4.10 or just swap the whole setup for a axle that already that ratio to slow down engine speed and be able to run and tow at highway speeds? If better to change ring and pinion, anyone recommend a brand or done this before?
