Rancho shock part number
 
Anyone have the correct part number for a Rancho 9000 shock that fits the front on a 2 1/2 lift for a 84 CJ-7?

Do a search on these, but I'll post anyway.

What I do, and it's never failed me, is take my own measurements. I measure the shock length at rest, then measure the space between the axle and bumpstop (or frame if you don't run bumpstops). Then subtract the axle to bumpstop distance from the shock length. This gives you the minimum shock distance you need, I usually subtract another 1/2" for good measure. Then I go to http://reality.sgi.com/rogerb/4x4/Rancho.html and look up the shock, with the right ends, that matches the "collapsed length" and find the longest one I can use. My older brother bought RS 9000's "for a 2.5" lift" and demolished them because his springs settled. I run a 5" lift and my springs are just right. It takes into account the sag and other lifts in combination. Let me know if I can be of further help and good luck.

JEEPN,
Thanks for the measurement advice. I am trying to cross reference a part number from Rancho to another brand. Then I was going to pull some measurements off that cross referenced part number. I recoginze how important it is to do a measurement. It's not only the springs that come into play, but the shackle length.

DRM,
They were Monroes. Thanks for the offer. I'll skip what I was going to try. I'll wait until I can get my hands on them and do a side by side comparison of the lengths.
