anybody know about 2-post hoists?

it includes the truck risers. he wants 2500. what's with the assymetrical arms? is that for more stability?

That's high, IMO, I don't care what brand it is.

You can get this 12K Atlas lift with FREE truck adapters and a five year warranty for just a little more.
