well here is another question for you, i have an aftermarket bumper on my xj and because it is all 1/4" steel my back end sags like 2-3 inches and it looks like crap cuz it has a 4" lift... would an ad a leaf be a good fix or is that going to just temp. solve it, should i just get new leaf springs? and if i need to get new leaf springs do i get the OEM or is there a different type that will hold its curve longer? cuz it loks like **** when it sags so much at the back but the front is still lifed...

 

I would try extended shackles.

 

add a leafs wont fix the sag new springs is the way to go full leaf packs for a 4 inch lift are available through just about every lift company out there rusty's has a 4.5 leaf pack pair for $249 plus shipping rubicon express you can get a pair or 4.5 full leafs for $350 i run rusty's 4.5 with a 2" bb on top of it i have 7" total the 4.5 actually measured out at 5
