I need thoughts and concerns on this setup. I am running a 5" fab tech short arm and would like to add a 2" spacer lift on top of that. Is this safe to do.

 

What size tires???

 

37" would like to go to 38"

 

I personally would not think about adding the spacers or any additional lift. There are people running 40's on 4" or less. That would be an uneccesarily high center of gravity. Just my 2 cents

 

I wouldn't think it to be unsafe but with short arms I would think your control arms are at a steep angle.

 

X2. I would rather keep the cog low and run 4" of lift and cut the fenders.

 

You would be better off with flat flares or a body lift for the extra tire clearance.

But, it's your jeep. If you want to add spacers: (and assuming you have the kit I am looking at on their site)

Front upper 'fixed' and lower adj ca's - shouldn't be an issue adjusting caster, but you'll be deciding between poor caster or driveline vibes. Consider cutting and turning the housing?
Rear lower adj ca's - you will want the uppers as well.
Front tb bracket / drop pitman arm - get rid of both, and buy a drag link flip and adj trackbar. (Synergy would be my choice)
Rear trackbar bracket - the axle will be offset. Get an adj trackbar, and then when you add the front flip, replace the fabtech tb bracket with a synergy.
Non-adjustable links - both swaybars will be angled down. Get longer links or adjustables.
Bumpstops - get new, taller, bumpstops.
Brakelines - it came with brackets? Get longer lines!!

Cam Bolts - Seriously ??? They replaced both upper and lower front control arms, and still uses CAM BOLTS ??? Remove them, have the holes welded back up. Remove the fixed upper arms. Replace with adjustable arms.

 

Your right I've decided not to go that route thanks

 

Nthinuf good advice ill hold on to that
