    What is the optimum way to raise the rear about an inch or two. I was thinking add-a-leaf but that would stiffen the rear. I know I cant do shackles in the back. Any suggestions?

    82 4in Lift. rear-blocks.

    "If it aint broke don't fix it" is like a 4 letter word.

    The best thing I would recommend is to contact the company where you got your lift and upgrade to 4" rear springs. Safest and longest lasting fix.

    I personally would ditch the blocks and put a 5 or6" spring out back. Otherwise the ORD zero-rate spacers rock. I have them on my rig... work great except for my current block setup [​IMG]

    Try laying off of the Twinkies.. LOL

    Really though, you could rearch the springs, get different springs (and ditch the blocks) or check out the shackle flip that was posted on here a while ago using a pickup rear shackle.

    Why do people keep calling it a Bronco!!!!! [​IMG]
     
  6. Yeah, and while you're at it, get on a Stairmaster! Really though, blocks are nothing but a detriment, they eventually wear out your springs. Any of the fixes suggested will work, but my personal opinion would be a shackle flip.

    Some of the people here have been recommending the shackle flip and so forth. I guess that would eliminate the need for the blocks, but I don't see what that would do for the rear spring sag. The only way to get rid of the sag is to either put in a spacer (like the ORD) or to re-arch the springs (by buying new ones or re-arching the ones you have) or a combination. I would be very cautious about adding a spacer without eliminating your blocks. You essentially already have 4" spacers in there anyway. Adding a spacer or an add-a-leaf is essentially like adding another set of blocks.

    I really think the best and safest route for you is going to be to either replace the springs with new stock ones and flip the shackles or to replace the rear springs with new lifted arch springs. I bet cost would be about the same while the new lifted springs would be less work. However, they would also sacrifice ride quality.

    Best of luck, but I definitely wouldn't insert more spacers if you already have 4" blocks.

    I had asked before about re-arching, and the only things I heard were that they sag kind of quickly, and add-a-leaves tend to make the ride harsher.

    Local shop wants to charge $275 to re-arch springs, AND put in an add-a-leaf. They pull them, they supply the add-a-leafs, all you have to do is tell them what height you want, and they do all the work. Not that I *like* people doing work on my truck, but the simple fact is that I can't re-arch springs myself, and there is no other way to guarantee your ride height will be correct.

    I'm probably going to have the shop do it, because I have seen problems with leaf spring kits not being the height as advertised (too much or too little) and if the frame is a little tweaked, or some other error in the height side to side, you can't correct it. 9the height problem, not the underlying cause) You can with re-arching springs.

    Just to clarify, the "spacer" that you are refering too is not another block. It actually goes into the spring. Not a big deal, even if you have blocks. Add-a-leafs are the same. You are essentially adding another leaf, the differnce is that the 0 rate leafs from ORD don't effect ride quality. I put an add-a-leaf in my 89 to bring the back up. I honestly noticed NO ride change in the truck.

    add-a-leafs MAY effect your ride. In mine, they didn't do anything to bother me. I honestly could notice NO change other than the back end sat up about 1 1/2" higher

    ORD's Zero Rate Spring.. it's actually more like a small 1-inch lift block you can add to the rear..
