do a shackle, add a leaf will just sag out on you again.

My daily driven weekend warrior has 216k miles on it and does 130 mile round trip commute every day. It is also lifted, but only running slightly larger than stock tires.

Just get a set of Cheap full length add a leafs, it will stiffen teh ride a bit but it will work just fine. Rustys are wicked cheap, like $60 and wicked easy to install.

do a shackle, add a leaf will just sag out on you again. That is prolly the most wrong statement i have ever heard. An aal will never saf as much as a shackle will sag a worn out leaf. I have done both, within a year the sagged leaf with the shackle was worse than before and the jeep that had the AAL was still sitting higher than stock. AAls are not that bad of a setup yea the ride sucks but for the money and for DD use they work great. stock with 30s, Looks pretty high but is really low, just pic angle.  2 Year old RE 2.5" aal, 30s  that AAl, rustys flares, and 32's (RE uses a 2.5" aal for the 3.5" kit.)  after 3.5" RE leaf packs not that much higher,  Pre aal lift with stock 225's  |

so thats just a 2.5 inch lift and u can run 30 inch tires with it? now what are the pros cand cons if i just did a body lift? someone told me they will eventually rust through the floor is that tru?

this is my brothers cherokee with a 2 inch AAL kit from rustys (the green one) and petes(pedro) in the middle before his lift. the green one has 30s on it.  |

how is it the most wrong statement you've ever heard? AAL's will affect the springs and over time sag. Shackles will be replacing the stock jointies and making them longer, in effect increasing ride height. Do yourself a favor and think about how a leaf spring works when it's concave and the shackle is behind the eyelet you can't sag any more.

I'm in the same boat with a saggy rear.....original springs on a '97 XJ that's been worked hard carrying/pulling weight. I figure the springs are shot - so why add another leaf to something that's already worn out? Why add height with shackles when the springs beneath are shot? New springs seems like the only way to go....then AAL or shackles for more height if desired.
My plan is wait until I have the funds and then replace with new springs - maybe a RE 3.5" kit.
How's my logic on this?

Do yourself a favor and think about how a leaf spring works when it's concave and the shackle is behind the eyelet you can't sag any more. A sagged xj leaf sages int he middle, and when you put a shackle on it that puts more downward pressure at the ends and over time it sags around the axle, My question to you is how does an AAL sag, ive run 2 of my own jeeps with aal's w/o any sagging, one for a year and one for 4 years with wheeling. stock leafs are too weak for a shackle. Believe what you want but i am workign with first hand experience. Shackles cause sag aal doesent. BTW did you notice how much that aal caused that second xj i put it in to sag? whooooooo it sagged so much the jeep actually looked lifted after i installed a used 2 year old all in old very sagged stock springs. |

"A sagged xj leaf sages int he middle, and when you put a shackle on it that puts more downward pressure at the ends"
you tell ME how a shackle put's more downward force....
kind of impossible since neither the weight of the vehicle is changing nor is the length of the spring, ie. leverage on said spring..

Thanks Will, i couldn't quite figure the wording to say that but ive seen it happen. I will put AALs in an xj any day over doing a shackle. its all about leverage and thats how the shackle causes the leaf to sag, i wish i had taken pics with the shackle BB on that second jeep before putting the aal or the leaf pack in. It was nasty upward arch with the shackle, then the aal to my amazement LIFTED the jeep and arched the springs correctly. Then omg the leaf packs lifted it more. 2 yrs later the aal went in to more nasty upward arched springs and OMFG again it lifted it like it was brand new. |

Will, lift blocks add leverage in a different direction and spot along the spring, so when torque is applied the spring is farther away from the center of the tube, causing longer travel in the leaf because it's farther away. Please don't try to get into "my logic", because you ended up welding your steering a week after I suggested it. We are talking about a different direction here, up and down travel, not torsional. when a leaf is flat it's at it's longest length. the shackle is a hinge. when it's on a lifted vehicle with properly arched springs (upward) the shackle is there to be able to give the leaf extension abilities. Sagging, or down-arched springs will sit the shackle in a similar position, which is certainly true with stock shackles. A longer shackle will force the body up along the angle of the shackle. The spring doesn't get longer, the shackle just provides more height off of it's pivot point, which is the body (not changing) and the leaf (not changing). When the suspension is cycling up and down with a worn out leaf flat, or sagging, it has to pull the bottom of the shackle in to take up the missing extended length from the leaf. when the shackle goes from a more horizontal(at rest) position to a more upright position (because the leaf is getting shorter from flexing, the distance between the leaf and the body increases.. how do you guys not understand this??.. If I have to I will draw a picture next post.
