Time, patience and engineering
Really, the truck started out as 59/41 bias and 3,900lbs with me in it. Last time at the tack it weighed 3,525 and had a 51/59 bias.
It started by putting an alum block and alum headed LS motor in it. (but that netted the 59/41 bias).
1) Find and remove everything you can in the engine bay you don't need:
2) Removed the front bumper
3) Moved the batterey from the front to the way back right (this does 2 things, takes weight of the nose front of the axle which has a leverage ratio making the batterey heavier on the front than what it really is, then it does the leverage thing on the rear making it heavier on the rean and actually lightening up the front more)
4) Went from power steering back to a manual box
5) Fabbed up a front crossmember from 2x4 square tube but retained the factory control arms.
6) Added 100lbs to the tailgate (Makes a huge difference on the rear and again takes weight off the front)
The fuel cell is also as far back as possible and the more full the tank is, the more on the rear/less on the front.
