I have a 2" bb i am going to add to my 4.5" lift. how do i put the shackles on? do i just unbolt them, do i have to jack the jeep up? also the coil spacers should just be use a spring compressor and put them in right?

 

yes you will have to jack up rear of jeep. Just unbolt leaf springs first then undo shackle and install new ones.

remove brake calipers to allow axle to drop a little farther for front coil install.

 

^X2^

 

not trying to steal your thread and sorry if i do, but if you are doing a shackle drop then dont you need to adjust the pinion angle as well?
