FWIW I have loved the OMEs on my various Troopers...tried a couple others but have always gone back to the Nitrochargers. They are very durable and ride great.

Note that the Trooper spec Nitrochargers are a bit longer than factory, intended to work with their OME lift springs. I doubt this matters much either way, but it is a nice touch for those with a li'l lift.
