Hey guys Im in the process of installing a 6.5 inch lift. In the rear I'm using 4.5 rough county full leaf packs with 2" shackles. I already purchased the IRO hack n tap. My question is are the supplied degree shims sufficient enough or will I have to re shim them with this set up? And is anyone running this as well

Gotta assemble and drive only way to tell.

alight well the jeeps sitting on all fours and i took some measurements last night in preperation for cutting. I measured 33 3/4" from the flats of the yoke to the output shaft and it only leaves me with just about 1/2" of splines. should i just cut it so theres an 1.25" of splines left? and my pinion seems to be pointing pretty much right at the output shaft altough i do not have a gauge to see what exactly my pinion angel is really at.

Angle sounds good ,where do hnt say to cut?

Fire_Busch92

It says measure 33 3/4" from the flat of the rear yoke to the output shaft and cut

What would that give as a center to center shaft length of u joints ? Just curious...

Fire_Busch92

Not sure I didn't have another set of hands to hold the drive shaft

freegdr

lol I meant measure between yokes on xj no drive shaft ...

Fire_Busch92

Oh lol I'll have to check tonight after work but I think I found the answer here

They say as long as I have 1" of splines left I'm fine I will most likely have to cut down the yoke as well

freegdr

You already have a shaft for rear ?

Fire_Busch92

Yeah my buddy had one from his old cherokee that he gave me

So I just called iron rock and they said that I need to leave an 1.5" of splines and i will have to get a custom drive shaft. I'm so confused now

Fire_Busch92

Well measured the shaft compressed and extended then remeasure the length from the pinion to the output with 1.25 splines and turns out I will be fine
