I do have a cheap, longer, Harbor Freight shaft with a 1 7/8ths ball I use for light weight trailers, but bought the official, shorter BMW hitch from ECSTuning, I believe, that I use when my trailer/load exceeds a ton or two. I have a 2" ball mounted on it. |
Yep. The manuals with the hitch are very clear on what the extension and drop max. limits are for the ball position. It is largely due to the offset of the receiver and the moment an extended load puts on the system. Specifics regarding trailer and tongue weights depending on conditions (live load, 6 vs V8, auto vs manual, off road, etc.) are also clearly defined in the manual.
