Question YJ springs on a CJ7

I need new springs for my CJ7. Im trying to decide between a RE 4" leaf for a CJ or a 4.5" leaf for a YJ... Im keeping the springs SUA, boomerang shackles on all corners, and running 33" tires. Is it worth the work to change to the YJ springs? Advantages? Disadv.? Thanks in Advance.

I did the swap to YJ springs years ago. I used BDS 2 inch YJ springs on an 86 CJ and it was awesome. The 2 inch YJ springs give a little more on the CJ because of how they are mounted, and I ran 34x10.5 Super Swamper LTBs on it with no issues. It rode better, cornered better, and wheeled better.

I would run the 2 inch YJ springs and cut a little of the fender for just 33s. Even SUA you do should not need the extra height in the springs and all the extra headache it causes, like driveline vibes, weird steering, etc., plus, it will keep your COG lower.

I have YJ springs on mine too.

I had OME leafs, they rode great, but after 10 years of wheeling, they were all bent up. Swapped to BDS 2" leafs, wheels great.

It opens up more options in regards to brands and lift choices.
