What type of lift if you're planning on adding a bunch of heavy crap to your car.
I mean Jeep.
I wanted about a 2.5-3", but I'm eventually going with new bumpers, and 35's, which means a 35" spare on the rear.
I've read threads about sagging with new bumpers and such. At that point, it is OK to correct it with a spacer or should a certain type of lift be considered? IIRC, the OME kit on one site had HD springs but other than that I haven't seen anything specific for this. I was originally planning on going with the AEV 2.5 or 3 as it's my DD and mostly going to be driven on road. However, I'd not want to get a 2.5" lift just to have it sag .5"-1" after putting all that crap on it. Also, how badly does that affect handling. If the springs aren't originally intended to take that much of a load, they'll probably ride rougher as they'll already be compressed from the extra weight. Rough is no fun when you're driving up concrete highways in PA.
First rule of thumb is progressive rate springs, also is yours 2 or 4 door? If 2 door then you wil have less movement as they are lighter than 4. I have AEV 3.5 on my 2dr and loaded it down with everything...zero sag. If you spend for a quality lift, you won't have much trouble.

Lifts with progressive springs generally handle weight well due to as more pressure is applied the coil gives more resistance. Atleast this is as I understand it. Companies such as AEV and others use these.
