long arm upgrade

i'm currently using a rubicon express short arm kit, works very nice offroad, but the onroad performance isnt too hot. i know that upgrading to a long arm kit will help improve onroad handling and also improve offroad. I am having trouble picking out a long arm kit though, please help with what you recommend and WHY you recommend that kit. I wanted the rubicon express 5.5 LA kit but its very pricey and i dont know if i can afford that, if thats the best option though, ill just save up some money.

How tall is your current RE SA suspension and exactly what shocks are you running? Also, what size tires are installed and exactly what tire pressure do you run in them?

With any reasonable height suspension lift, there is no reason for a short arm suspension to not ride well. My current Currie short arm suspension with its OME shocks rides as well, does better offroad, and handles FAR better than my previous TJ with its RE long arm suspension ever did.

4.5 RE with a one inch body lift. Ive been told that the ride is superb compared to what im currently on. I just upgraded to rancho 9000's and have them at 7. the tires are 35" BFGs. It all works pretty damn well offroad, I am just looking for a better on-road ride since this is my DD. the geometry of the body lift on the short arm kit just feels almost too stretched, i could be wrong..i should probably take a ride in a jeep with the LA kit and see the difference.

Running Ranchos at 7 would make any Jeep ride like a buckboard wagon, I'd try turning them down a bit. A body lift has nothing to do with any geometry of anything on the suspension or steering. Again, what tire pressure are you running? Properly set up, a short arm can ride, handle, and offroad just as well as a long arm. Especially an RE LA as I used to run.

Standard misinformation from the mouths of the uneducated. Listen to Jerry.

Agree that Jerry is the man.

If you want to go to long arm, look at the Rock Krawler upgrade kit, it is just the arms and belly up pan, you can keep all the other stuff from your lift.

Just my 02.

ya but then it sways from side to side like a frickin boat if the shocks arnt stiff. also if i were to upgrade id completely remove my kit i have, sell it and put a whole new LA kit because id remove the BL. My tire pressure i run on the road at 35psi. off road i deflate some of course.

Might want to try a lower pressure in your 35s. I typically only run 26-27 in my 33s.

i just want to clarify my main problem here is daily road performance with my suspension setup. When off-road everything works very well! especially with my new eaton e-locker (: is it true that the geometry of the LA kit will improve on-road performance? this is my DD.

Your tires will make a world of difference at a lower psi.
