LCA installation

Ive just purchased 4.5" Fixed LCA's, i plan to throw these on there when i nstall my 2" spacers, how do i got about the installation of them? Also if im installing the Spacers at the same time, do i need a spring compressor? or will the axle droop enough for me to get them in there?

If you have as much flex as badger you shouldn't have a problem dropping a spring...

I envy his rig.

If you are replacing LCA's during coil spacer install, you should not have any problem as you should have plenty of axle droop. If you do get a compressor, make sure it is a strut compressor not a spring compressor.

Any imparticular advice as to geting the stock arms off? are they difficult to get off? when i unbolt them will the axle fall and if so, should i jack it up?

You'll want to have support underneath it. Also, spray the crap outta those bolts and stuff with some PB Blaster in the few days before the process. Good luck with the install.

i just repalced mine, and added a spacer. jack up the jeep, place jack stands underneath, and dont completly lett he axle droop but just about..remove the arms from the axle, and disconect the track bar and sway bar and ur axle will droop enough to not need spring compressors. then chuck on the spacer put the coils back in place push the axle forward. put on the arms. and u should be good to go. o yea dont forget to disconnect your shock on the axle mount. u dont want the weight of the axle hurting them if u leave them connected.

And you didnt have to touch the upper arms?
So, correct me if im wrong, but your at 5.5" and you did not need new UCA's? Becasue im really hoping that im not gonna need Uppers.

"should have" and "need" are big differences.

Yes, you should get new UCA if you're going 5"...

No, you don't need them...

You will probably get less vibes with new UCA as they will help to correct the front pinion angle. When you put the longer LCA on, it will point your pinion more towards the ground than before, but not enough to do any real damage, other than prematurely wearing out ujoints.

i need to fix my sig...im at 4 inches. i replaced the uppers and lowers...but this thread was only discussing the lowers. i dont have the money for a while to go to 5.5

i would get yourself a set of uppers as well, i just re read ur orignal thread the short upper arms are gonna pull the axle upwards, and make the driveline angle really off. i dont see things going to well if u leave the uppers stock.
