I started with the OME HD springs and eventually swapped them out. They didn't really net the lift I was looking for, and it was crazy easy to drop a spring on the trail when disconnected.2004 with the 4.7 and QTII sitting on OME HD springs and Bilstein 5100 shocks with IRO extended sway bar end links. IRO high clearance trans crossmember and tcase skid plate (sitting in garage). I have an NP242Hd tcase sitting in my garage to rebuild with a SYE kit. JK 17" wheels with 31" Falken AT3W's. Fawkes Fab shackle tabs with bullbar relocation running a Texas Hunter bullbar with Amazon LED's and a custom tab for the CB antenna. Yakima LoadWarrior w/ extension running an ARB awning on FourTreks mounts. Breather extension in the works. Bout to address the sag in the rear end before much longer. Lots of interior mods.

I moved over to IRO 4" springs and have been very happy. The 4" IRO springs are about 4" taller than the 3" OME Spring when sitting side by side. The taller softer spring has never come out. To be fair I also added spring retainers at the time of the swap but I've seen no evidence they have come unseated.
Got yourself a nice build going on!
Great photos!
