I lifted my truck 3"s using 2'' light load spring and 2'' spacers as my rig has a arb bull bar and rear bar full belly bash plates and roof rack it brings it to three where i wanted it to be so its practical for my family to get in and out, now with my rear lower arms i can near deffinate say they are under stress constantly with the lift where the arm meets the chassis cause the bush is squashed at the bottom of the mount on 1 side and on the other at the top as if it were flexing out witch is where my droop being only about 2 inches comes in, i took into concideration cranked arm but i belive i have a better idea but dunno if anyone has tried it?? here goes, ill buy another set of arms cut the head off that mounts too the chassis and the to the diff throw the arm away, now using the other arm i cut off the chassis mount end again and weld on the diff mouting point i cut off the other arm (keep in mind i want the total length of this to be the same as standard in total) from here the chassis mount i cut off the arm i weld a bracket to it that the arm can bolt to and when bolted making a full 180degree point so to speak when it isnt in the car refit the unit and do the same with the other side. assumeable i believe it would work better than cranked arm as it thieoreticly has no real droop or squash limit by the bush as the arm can free swing and all the bush will do is rotade its position as the diff moves up or down, what are your thoughts?
