My Trigos are not FIA's but yes, it seems the rears may be thicker because the do not seat as low as the fronts. I've never measured them but the eyeball test says there must be a difference there.

I have 12k on mine over 10 years so it hasn't been an issue for me. Just make sure you use liberal anti seize, whack the snot out of the spinner (with the wheel on the ground. Pounding on the suspension at full droop no bueno) and use safety wire.

HTH,
