AGR offers a 16/13:1 variable box (#204352) - this is the stock box for these trucks.
A 14:1 isn't a fast ratio box, it is basically a non variable box version listed above. Another words, it if isn't faster than 13:1, it is the same speed as the factory box.
Fast would be 12:1 or less (like a camaro/S10)
They pumps aren't that special either, just higher pressure valving. I have both the box and the pump...
