can i throw in 2'' AEV spacer kit into a RC 2.5'' suspension lift kit?

i just got a 2.5'' suspension lift kit on my 2012 JKU, but want to put on a set of 37s tires in this summer. i think it will be much better if i get a long arm kit and at least a 4'' lift. can i just add a 1.5'' or 2'' spacer kit on the RC 2.5'' suspension lift? will the jeep be screwed up by the spacer kit?
and please give me any advice if i want to put on 37s tires even changing the whole set of lift.
thanks...

Yes you can.

You don't need a long arm kit to run 37's

my friend said the long arms will make the jeep much more comfortable. haha...

i still need to put on new sway bars, track bars and so many things like those to fit my 4'' lift, eh? cause my 2.5'' lift kit just came with shocks and springs, nothing else.

You friend has a lot to learn
2.5", a good mid arm setup and longer shocks. Flat flares is all you really need for a great setup

4" you are probably going to need new driveshafts. CA's for angles. Adjustable track bars. Sway bar links. Possibly a flipped drag link/high steer kit.
Longer shocks or your just going to max them out.

37's and your looking at regearing/ball joints and other means of strengthening the front axle.

I know I am missing some stuff. Just know what you are getting into at 4"

i thought about just running 37s with the 2.5'' lift, but i prefer higher lift for bigger tires. i will regear and get a diff guard to make the axle stronger. by the way, what the "CA's" meeans? i think if i am running 37s with 2.5'' lift, i will need fewer things than a 4'' lift. sway bars, track bars, regearing, diff guard. anything else?

By strengthening the axles I mean gussets/sleeve or some sort of truss.

CA= control arms. At min front lowers and rear uppers for pinion angles.
At such a high lift the axles get pulled in so its best to run all 8 arms.

You still should be running longer sway bar links even at 2.5"

Google 2.5" and 37's. see how people are set up.
