Rear Springs Lift

I just put Crown heavy duty front coil springs in my 99 Cherokee 4x4 and now the front is 1.5” higher in the front than the rear. What is the best and cheapest way to raise the leaf springs up in the rear 1.5 inches and a quality install.

Some version of an add-a-leaf.

The easiest way without changing the spring rate would be some longer shackles. If you want stiffer springs then use an add a leaf. I am not a fan of blocks.
You could also do shackle relocation brackets that will give you more articulation if that is what you are looking for.

Like I related in the linked thread about low cost options to add lift, extended shackles will ruin a stock XJ leaf spring pack, and a full length AAL is slightly firmer than stock, but is not objectionably firm. Using a stock XJ Cherokee leaf pack for a donor add-a-leaf results in practically the same spring rate.

I’m going with Dorman or Crown heavy duty rear leaf springs probably Crown. For the money I think that’s best per the posts here. Thanks again.

I bought the Crown 4886186AB HD Leaf Springs. So confusing with different part numbers and letter designations (AA, AB, Etc.) and arch height. Some say these are equivalent to UpCountry some say not. Anyway those are going on my ole 99 next week. I think they will be a little harsh without load but that’s ok. I have the same brand Crown HD coil springs on the front and I like them. Time will tell.

Add a leaf will change the spring rate from what is currently is. Longer shackles will keep the same spring rate.

Like I related in this thread about low cost options to add lift: https://www.jeepforum.com/forum/f11/c...vs-rls-640285/
.
  • short add-a-leaf are very stiff and are not a good lift option
  • long full length add-a-leaf only slightly increase the spring rate
  • extended shackles on stock leaf springs have a substantial risk of ruining the leaf springs.

Had my order in for a week and today Morris Tells me out of stock with no ETA. Crown Springs 4886186AB and Dorman 929-301 for Cherokee are imposible to find right now. I did find OMIX-ADA HD and cheaper. Anybody have experience with OMIX-ADA?

I don't understand how this will happen, please explain, I was going to put on 1"-2" shackle extensions

Since they are longer they allow the spring to flex more. Bend the leafs too far, too often and they lose their spring. So eventually they will sag and possibly invert.
