say what you want about the Sh!ttiness of the RC lift. I run AND wheel it, HARD too. i've had no sagging issues yet, its not that i dont expect them but i'm happy with the lift, the way i see it, a leaf spring is going to sag, yes in the future i will invest in a "better quality" spring. But the RC springs do actually work and they have a lifetime warranty, so if they sag, they get replaced. i got no problem with that.
