This is an old thread on what I did for a budget lift
Gen 1 Budget Lift

I've had these spacers in for some time now and have had no problems.
Ray,
I don't think they will come out on their own (extreme flex) as I had to compress the coils so far to get them in. No problems yet but I do still have the rear sway bar on.
Happy Trails
Bob
