ready lift

I was just looking at these leveling kits called ready lift and I have to say that it looks like a badass product. It claims to not interfere with the ride at all, guaranteed for the life of the vehicle, and only costs about $230. Does anyone have one of these kits and does it live up to what it says? Still ok to do some off roading?

 

what kind of lift is it? suspension? body? spacer?

if it is a spacer type of lift i would think off roading would void the lifetime warranty, those kind of lifts are fine if you never leave the pavement... better ready the fine print on this one.
