99 XJ stock. Rear sags by almost 2 inches. I am looking at replacing the rear leaf springs with the Rusty's 3.5" leafs. Will this put the back up more than 3.5" or will it be more like 5.5" If I regain the sag and then add 3.5"? I want to do more than just the AAL to compensate for the problem by just replacing the leafs all together. It seems that the Rusty's leaf would be better than OEM leafs for only $20 more.

 

If you are replacing the leafs then you get what is advetised for lift, maybe a little more. I have Rusty's 3" leaf packs under my Jeep and they look almost like 4". Great product for the price, just make sure you order the whole 3" kit not just the rear springs. Also get a TC drop kit, you'll need it on the newer body style XJs.
