I've had front 2.5" Superlift Superride springs for probably 5 years now. No breakage or sag yet. They were used with a diesel 6.2 for a couple of years, 33" tires for all but the last year, now they're 37" tires.
The rear is okay, but the 3" TC springs have only been in for a year or a little more.
