|Plumber1||I have no personal experience with a LA kit other than seeing them dragging a lot on the Rubicon. And a Jerry stated above I also run a 4" SA Currie kit and it rides and performs GREAT.|

|Jerry Bransford||My previous TJ with the RE longarm suspension was stolen with that suspension still in place. And yep I'm back with short arms (Currie) in my replacement TJ... there's nothing the RE suspension did that my current Currie suspension doesn't do a lot better.|

|Ironhead Jed||he switched to short arms before he lost that jeep, IIRC|

|jjvw||Very interesting, since Jerry ended up losing that Jeep. On his new one, he now uses and prefers short arms, correct?|

its interesting reading the thoughts on suspension from 5 years ago.

With everythiing else being equal, a long-arm rides better on the street when compared to a short-arm at steeper angles. COG wise, they give the same COG as a short-arm does when everything else is the same, no difference. And a long-arm doesn't require a SYE any more than a short-arm lift does either, everything else including the lift height being equal.
For most wheeling, my long arm suspension from RE performs exceptionally well. Its only real issue is that the added control arm length & exposure means the control arms can get hung up on some trails more easily. If I'm on an extremely difficult rock crawling trail like out in Johnson Valley, my long arms give me fits as I get hung up more than I like... much to the enjoyment of my buddies who aren't all that impressed with long arm suspensions.
The two below pics show two of the several locations my long arms got hung up on that day on Sunbonnet in Johnson Valley. That second pic/poster was done by a buddy who loves to give me crap over my long arms.

x2. My 6" long arm is really good on the street. But, I have a Rubi with the stock SYE setup and a Fabtech lift.
Generally, the rule I mentioned stands. Of course, I'm comparing that to a 3-4" short arm lift vs. a long arm...

Mine rode much better after the conversion to long arms than when stock on the road and naturally off road as well.

Long are advantages:
- more flex
- much better geometry (on TJ's anyway)
Long are disadvantages:
- more expensive
- not generally as street worthy
- give you a higher center of gravity
- usually requires a SYE
Short arm advantages:
- cheaper lift
- better street manners
- usually easier to install and maintain
Short arm disadvantages:
- less flex
- usually can't get high enough for 35" + tires w/o body lifts and/or cutting to clear tires.
Converting a "normal" suspension to a long arm is typical. Essentially, you do a lift for bigger tires and what type of wheeling you want to do.
Doing the lift twice is not good on the wallet, so get what you need to wheel where you want. Avoid a 4" short arm if you need the 6" and want bigger tires to rock crawl.
Get the 4" short arm if that fulfills what you want to do with the jeep.

long arm suspension vs normal suspension lift
what the difference between the two advantages and disadvantages. also can you convert a normal suspension lift to a long arm suspension lift?
