for the 1-st and 2 gear. Does enybody knows enything about this? I read from Legendary Ford, but I dont find enything on their home peige. Thanks!
Basically it gives you a steeper first and second gear so you can get out of the hole quicker without running tall gears in the rearend. If you are not racing I wouldn't worry about it.
Thats the idea, I race little bit and I mast drive interstate too, the raceing is on the different places, more/less 100miles one way.
