Read all the posts for more info Right above your post I said that I just swapped mine and do not need adjustable arms. To each his own though, I guess some need it and some don't. I think you can get away with it more on the front, definitely not on the rear though.

 

je reel 1310 now that is "adj" front lowers right..

 

Has anyone read this thread or just see "control arms" in the title and reply with a question. It's all in the second post of the thread and quoted just a few posts before this one. Planman laid it all out and I dont think there could be a more clear explanation. Go back and read it and if you don't understand then post up the part you are having a hard time understanding so it can be explained.

 

that is the best response on arms I have read on here but in response to this for 2 door.... what about 4 door and 4 inch teraflex.....

for 2 door.... 4 door?????

At 2.5" to 3", you can go with either adjustable front uppers or lowers to inprove your caster specs.

At 3" on a 2 door, you may eventually need to run an aftermarket driveshaft along with adjustable rear uppers.

In either case, at 2.5"-3" there is no need for all 8 adjustable arms, and the money could be better spent on other upgrades.
