I've spent the day combing threads for info on OEM rear leaf springs for the XJ. Someone else may find this helpful. A grain or three of salt is needed on specs, I'm relying on other Jeepers in main.
There are [8] part numbers listed by Ma Mopar for the 2001 XJ:
1] ZPS/ZUS 52000-050AB Standard Duty coded LB
(no other info)
2] ZFT/ZUT 52000-051AB Standard Duty coded LC, EC
3-1/8" free arch, 405# rated (standard 2WD)
QUADRATEC Standard Duty 56010.12
3] ZGU/ZVU 52000-707AB Heavy Duty coded LM
5-5/8" free arch, 605#
4] ZFU/ZUU 52000-706AB Standard Duty coded LN, ES
6-5/8" free arch
5] ZGS/ZVS 52000-544AB Heavy Duty coded LK
(Either 5-1/8 or 5-3/4") free arch, 575#
QUADRATEC Medium Duty 56010.10
JEEP 4886187
6] ZGT/ZVT 52000-545AB Heavy Duty coded LZ, EL
7] ZGV/ZVV 52000-390AB Heavy Duty coded LS
6.0" free arch, 675#
JEEP 4886185 (CROWN H-D; 6-3/8" f/a?)
8] ZGW/ZVW 52000-329AB Up Country (+1" height) LT code
7.0" free arch, 755#
QUADRATEC Heavy Duty 56010.11
JEEP 488186
JEEP TSB (NOV 1996) "Leaf Springs Sagging/Low Ride Height" may have info on spring rates, etc.
I'll post more if I find it.
Second job today is to hopefully find rate info on the fifteen [!!] coil springs posted for XJ's by Mopar. I'd like to change the rear springs from 405# to 575#, but, as I have a 2WD I'm stumped at this point as to what front spring to change to. This XJ may have a little towing to do in the future, so a slight rate increase would be helpful. (If I find nothing else, maybe a new set of ZFT's plus a full-length AAL and straight replacement front springs, hmmmm. Or, since I'm already running OME shocks/stabilizer maybe I'll give Dirk a holler and let him ponder it for me. He already thinks I'm half-nuts [probably] for this being the second 2WD I've changed this to).
Good luck with your searches.
