Only problem is the unit isn't tall enough. With my 33's, the unit just barely has enough lift to raise the tire 1/2" up off the pavement. <img src="/forums/images/graemlins/confused.gif" alt="" />

I've gone with either a big monstrosity of a floor jack or my hilift.

Oh, after the initial incident in Utah several years ago where my jack had not been oiled, I now relube mine every 2-3 months.

Regarding danger, yes they can be if you aren't careful when switching from lifting to lowering, the arm has a tendency to kick back. Not severely, but enough to smart quite a bit if you're not careful. You just need to be careful when lowering for the first 3-4 strokes of the hilift. (boy, in a different state of mind, that would sound quite obscene.. <img src="/forums/images/graemlins/evil.gif" alt="" />)

You have to apply downward pressure to the jack arm on the way up when lowering your vehicle, versus applying the pressure when pushing it down during the lifting.
