I bought my jeep a few months ago since then I put in a spacer shackle budget booster and my back end seems to be sitting rather low. I looked at my leaf springs and there is almost no arch to them. Should I buy new springs? Get them re-bent?
The extended shackle has put extra stress on your 14 year old leafs and accelerated the sag that comes with age. Longer shackles are not a great choice for stock leaf packs - especially old ones.
You need to either replace the stock leaf packs, or rebuild what you've got into a bastard pack. If you were to grab the main leaf from another XJ, cut just the curving up part of the eye leaving as much flat leaf as possible, you could rebuild what you've got.
Other BP donor choices are Explorer, Dakota, S10, Dodge Van - any 2.5" leaf will do, but you do not want to get a thick leaf that will stiffen the ride too much.
Stock leaf packs are soft, flexy and lightweight for a smoooth ride and don't deal well with the extra stresses extended shackles bring. Those leaves are worn out and lost their arch. Get some new leaf packs, but not OEM if you're looking for added lift.
"You can set my jeep on fire and roll it down a hill,
But I still wouldn't trade it for a Coupe DeVille."
if you want stock ride and height they replacing these with oem's is the fix
if you want to change height then you have quite a few options in regards to the packs (bastard pack / add a leaf / different now oem leaf pack)
its kinda a preference deal
I already have the shackles, I want to make the clearance in the rear a little more, every time i go wheeling the rear only hits. I just want my back end to look lifted, to me it looks stock now. I'm not too trusting with used leafs, but would i just be better off getting AAL or 2 new leaf packs.
I am going through the same quandry...i've gotten in touch with Morris 4X4, since on their site, they list 9 different springs with 9 different arches. Anywhere from 5 1/8 arch to 7" of arch. All of them have 4 leafs. Dont want to ride like I'm on a sled...my YJ does that, BUT, I don't want to feel like im on a marshmallow either. So when I hear from them, I will let anyone who is interested know. By the way, the jeep is a 98 with 85,000 miles, no rust, everything works, and it was free...lol. so I think I'll keep it and get rid of the TJ I have..Will keep you all posted if your interested....
Don't add AAL's to your saggy OEM leaf packs.
Look up "shackle relocation brackets". Depending on the length of your shackles, and the angle you install them at, you'll add about 2" to what ever height you are at.
If that's all the lift you want, then get new OEM springs and spacers for the front coils to level it out.
If you want more lift, just keep in mind the 2" the brackets add.
There is also a way to net less lift by using one brand of bracket that requires you to cut out the factory shackle pockets.
