What's the deal! I put rear waggy springs on the back of my cruiser and they're too soft. Should I have used front springs.

I used front waggies at all 4 corners.

Interesting that those rear waggies are too soft for your fj(40 I'm assuming) considering they hold up those fat and heavy waggie boats. Are you SOA or SUA? Did it appear that the overload leaf was missing?

what kind of mount relocation is needed for this swap?

6 out my 8 mounts are custom and it has been so long since I had a "stock" spring on there I can't remember where the stock ones sat so I can't help you too much...sorry.:(

that's what I thought, that the waggy was a tank. I did take out one spring that was about the third longest, but it is really soft, or maybe it's stronger than I thought..I moved the front hanger foward about two inches and the rear one back not enough, that might be part of my problem. It ended up with too much shackle angle. I was looking for 35 degrees but got a lot more which is no doubt adding to my problem.It's soa.
