Which rear gear ratio '13 EB

[Willie2]

Which gear ratio did yall go with? I assume the 3:15's get the best gas mileage and the 3:73's will get out of the hole better. I plan on doing a ecoboost tune.

Also, can you tell me what the difference is between the non-limited slip and the electronic locking axle is?

thanks.

3.73's is what I have and it moves out. I get around 20 mpg on highway

Non LS rear ends are an open differential and only drive one wheel. The elec. locking rear diff. is where it's at.......just a flick of the switch and both rear wheels will be locked in together and transfering power to the ground together resulting in much better traction.

On my 2011 EB the FX4 package had 373 gears. I get around 20mpg still and it has awesome throttle response.
