i picked a set of comanche shackles today at the bone yard so im wondering how much lift it will give on average? and can they be hung from the factory xj shackles for even more lift? ive seen guys have other shackles hung from the stock xj ones. i got some teraflex 1 1/2" coil spacers for the front but there not in yet

 

i think it'll give ya 1 inch lift over stock.

2 inch shackle gives 1 inch of lift.

 

im not sure, but i thought it was 3/4" over stock

 

its about 3/4"

 

they look twice as long over stock...can i hang them from the stock shackle? or will that cause problems folding up?

 

it will cause problems

 

replace the stock shackle

don't double them up

 

yeah, only use one shackle, don't double them up.
you can use an xj one or the mj one. not both.

 

why do people do it?i geuss they could be welded together if you do it right but the amount of lift vs work proabably isnt worth it unless one is very bored and itching to fabricate im going to just swap em out tomorrow after i see what things look like after the front coil spacers are in

 

You can also use chevy drop shckles form the 80's they measure 83/4 eye to eye

 

i've never heard of people doing this, maybe they want a ghetto redneck version of the teraflex revolver shackles.

sounds quite dangerous to me. maybe if it's only a field truck, but i still don't think it's a good idea. it can and probably will fold up and drop the driveshaft. not to mention, it will bend or break on a side load.

be safe. build it right.
