The time has come... long or short arms, I can't decide.

I have been on short arms at 4 to 4.5" lift for about 9 years. I ran drop brackets to improve the on road behavior but I did not like the rock anchor experience that drop brackets delivered. You can get short arms to flex tremendously well if you put some time into shocks selection and getting your brake lines long enough:



I found that the best money I ever spent was on good skid plates and then raising my rear shock mounts level with the axle center line. Cheap and a huge improvement in wheeling performance. Long travel soft springs (V-6 T-Bird) and good dampening (12" travel 1960 F-100 Monroe) shocks on short arms have been a great combo for me.

That said I am now installing long arms. I need more travel and I want to go a lot faster off road. With speed the steep angles of the short arms are unacceptable. Trail riding and crawling short arms at 4-4.5 was not a problem. Speed demands shallower control arm angles to keep the tires under control.

You might want to look at you spring rates and shocks before jumping off the long arm cliff. If your rates are below 180lbs/in and your ride is too rough for your tastes then your only answer is long arms. If your rates are over 200lbs/in you can easily improve the ride with less spring and more shock.

Edit: Dont get the metal cloak variable rate springs (I think they may be JK only, so it may be a moot point). Seems like a good idea but the small number of free coils at ride height give a stupid high initial rate.

I do have Rusty's 'light duty' 2" lift springs. I think they are 180lbs. This along with the ACOS give me 4-4.5" lift. I also have 5150 shocks... it's still somewhat harsh. I'm thinking long term and will be adding a bumper and possible winch so I'm looking at heavy duty 3" lift springs. I really want to stay around the 4.5" height range. At this point I'm 99% sure it will be long arms over the shorts.
 
Im confused as to why or how this is even still a question..
 
4"+ I'd go long arm.
Under 4" I'd stay short arm.
3-3.5" short arm will ride well on road and with the proper length shock and rear suspension setup it will have great articulation off road.

I'm new to all of this.. I just got my last XJ last year in stock form. So I'm learning as I go. Also, alot of folks build their rig just for offroading.. I'm shooting for a compromise between an overlander/offroad crawler/DD set up. All the info posted is valuable to me here as most of the folk has run may different setups, and there are a lot of ways to go. Plus we are talking $700-1000 expense, so I have to be sure... I only want to do this once.
 
Long/mid arms for sure.
 
Are you going to build or buy a kit?
I would recommend bushings on the axle side, and good quality heim joints on the frame side.

Is this a good setup up for a rig that daily drives at least 30 miles everyday? I hear heims are just not the way to go on a DD. I like the idea of heims but flex joints seem to be the choice for any DD rig

I have mid arms with bushings on the axle side and 1.25" heims on the frame side. No issues, rides much better than short arms. My DD is down currently, so I have been driving my heep. No issues. Even drove it to Moab for the 30th last year from California and back.
Barnes4wd has some enduro joints that I may try eventually. Brian from HDOR gets a decent discount from them.
 
I'll get some pics when it's not raining and wet outside.
