They're just average. Not the best, but far from the worst.
If you want a good lift go with a brand like Currie or Savvy. Zone is a good brand if you're on a budget.
Rokmen also makes some nice stuff as well!
Thanks Chris... Zone huh? Interested that you and Jerry both mentioned them. I really don't know much about them. Trails here in N. Georgia are disappearing quickly so leaning towards a more budget friendly suspension since I'd not have the trail system to justify going big. I really appreciate the info.
