T think they told me once that they were superlift springs? but I'm not sure on that. I'd be surprised if they weren't pro-comps, since they're all about shoving pro-comp everything down everyone's throat, no matter what it is. but I know when I was just price checking on a lift, he started checkin on that one (even though it wasn't what I wanted), and when he started adding it all up, he ended up working on a different kit, because it was gonna be cheaper in the long run, so I'm not sure how complete that kit is. but, I don't think it was on sale at the time, so...that might make enough difference in cost for it to be worth it.
