How long would it take for a experienced installer to install a complete 4" cognito kit?I have a longer front drive shaft so I can drive in 4wd at higher speeds without vibration. The front steering is your weak link, but not because of the lift. I have the cognito pisk system(pitman/idler support bracket).
On the old frame a 2 inch rear will probably be pretty level. If i did it on mine it would have an ass high position. You could level the older frame and still be decent ride. If you truly try to level these the angles and ride suffer big time. So I have absolutely no lift just bags in the rear. I did not have to put a carrier spacing. With a 2inch rear I would be shocked if you did.
My steering box lasted over 100k. It will go but not due to the lift. I run kryptonie pitman arm, idler arm, tie rods, wheel hubs and lower ball joints.
I think that covers it.
