I have a 2004 4x4 later on down the road I want to turn it into a prerunner. Since the 4x4 is not necessary for my application I want to know if the only difference between 2wd and 4x4 torsion is the spindles? I have seen the Dixon bros kit and I think it's sweet but for the money saved on coilovers I could put it in the rear suspension. I want to use the camburg upper control arms and spindles and use some better resi shocks than the crappy 5150 bilsteins it comes with.
