I have 285's on my 2014 JK and want to lift it 1.5-2". I was looking at the TF leveling kit or possibly their kit that levels using new springs. When I mentioned the leveling kit a local "expert" says watch out for them the spacers wear out. Need input.

I can't see how. There is nothing to wear out. I've never heard of a single spacer failure either.

Well, technically the spacers are hard rubber, so it is possible over the years they do compress a bit. I'm just throwing this out there, I've only had my spacers on a year so no real world experience with compressing.

The spacers are polyurethane not rubber and are actually more durable then metal spacers as polyurethane doesn't corrode from the elements and is very very strong.

I remember holding them in my hand....thought they were rubber. No matter.

Back in the day (before internet) I made my own coil spacers for my TJ out of composite deck board material. Using a jigsaw and a router I made a nice 2" spacer that lasted the five years I owned the TJ before trading it in at the dealership.
So, I'm sure the current options on the market will last forever.
