What control arms for a 2.5" lift?

I'm putting a 2.5" lift on my LJR with 32's. I have the springs and shocks and need to get the control arms. The plans are for 38's and an LS but that's a few years down the road due to lack of time, so for now I just need to freshen up the worn out suspension.

I wheel the Heep several times a month. What short arms would you recommend?

Stock arms, until you get rich enough to properly run 38s.

What "good set" of adjustable arms are you running?

Currently Rubicon express non adjustable
I will be getting some RockJock arms when I lower my Rubicon this fall.

Factory arms, why spend coin on something you plan on replacing

unless you are going with a tummy tuck as well, it doesnt make much sense to swap out the arms. most aftermarket arms are a downgrade so why cough up $200+ per pair for a decent set that will be a tiny upgrade over stock when you'll be going to a fully custom suspension when going to 38's? i guess the argument could be made that you could reuse the johnny joints from a decent set of arms, but if you're going full custom why not start with exactly what you want.

Stock arms are certainly fine for a small lift. However, I tend to think that a lift can make worn components more visible. Even the newest TJ is 15 years old at this point. The bushings in some original arms may be worn. If you decide to keep stock arms due to their flex, it might be good to put a new set of stock arms in so that you have new bushings. A set of cam bolts for the front/lower arms will allow you to add a small amount of caster back in after the lift, so adjustable arms are not necessary.

The 38s and LS swap are most people's pipe dream. My brother's tuned F-150 Ecoboost twin turbo puts out more HP and torque than a Hemi V8. Hmm. Maybe if he wrecks it I could do a swap.
p.s. I waited on his viper v-10 Dodge truck for the same thing. Not happening.

You sound like my accountant. Very sensible. Cam bolts are a BS thing to sell crap to uninformed people. I will put them on my list for tax deductions.

What was the final verdict on the Metalcloak Duraflex arms?
I can't remember the forum member that started the big write-up on them.

I disagree on the cam bolt. There is quite a bit of adjustment that can be achieved. You just have to keep both sides the same.

I have MC arms. I like them.

Imped did the write up.
