How much overdrive should I have in the front axle of an Outlaw stock truck?

Overdrive wastes power.... keep it down around 2 or 3% to help you go straight... if nothing else, run the same final drive front and rear. (never slower in the front whatever you do!)

With the gear combo I have I can get .07% or 3%. whitch would be better?

If you run deep stuff most of the time, run 3... if you want speed, try the .07, but you might be steering a little. The 3% would probably be my first choice if you run both types of tracks.

Also make sure you take into account the difference in tire size if you change tires( using 44 boggers and 36" scoops) They will give you different rear numbers so you have to adjust accordingly with your front overdrive. I have 1 % overdrive with my 44's and 6 % with my 36" scoops.
