I am thinking of getting these to help the sag in the rear of my xj. Anyone had any exp?

These show to be for coil sprung applications. Not sure if they would work, but check out ride rite by firestone. They make them for leaf sprung vehicles and I have heard good things about them.

 

Could I use them for up front? Or should I not bother

 

I wouldn't bother, but it's your rig.
I'm not really sure what good they would do. The way I understand it, these are designed to be helper springs for trucks when carrying a heavy load. Basically, when you have a bed full of crap or a trailer attached, these inflate to level the rear of the truck. They may work, just not sure exactly...

 

I am just wondering what to do to help my rear since I will eventually pull around 800 to 1k of weight in the back.

 

Those firestone bags may be the way to go then. If you're going to be carrying a lot of extra weight around, they would help if you can get them installed on there. Just dont know how to do it myself. I know they work well in trucks.

I was originally thinking you wanted to use these in place of lift springs... which would be a bad idea.

 

No I just want to fix the sag. I was going to do a basterd pack

Just install the proper set of good quality leaf springs and be done with it, either lift or just HD OEM's like from Dorman. I carry a lot of weight in my cargo area all the time and add more at times to the roof carrier. I have a very heavy rear swing out tire carrier bumper with receiver hitch.


Even with everything loaded down I have less than a 1/2" of sag and that's only when I have extras on the roof. Leaf springs are cheap and you will know the job is done right. You could go to a spring shop if you have one close to you and have a set built for your XJ's needs.
