The one I have isn't offset. If yours is offset, I bet you installed it backwards!! The reason that the mounts are offset is because the right side mount bolts to the outside of the rear subframe, while the left side mount bolts to the inside of the subframe!!
Flip it around and I bet it will be balls on!!!
I got one of these and am very happy with it

Just like an AC racing one, only cheaper!! Probably better made also!! When I first installed it, I installed it upside down, and it was all crooked and such....I was like WTF?!?!!?!! And then I realized what I had done!! Now it's ballz on. Love it. Way easier to grab onto the rear and yank it out of the mud!!
