Question:
Hello,,,, wondering the shank amount I would need for a 2017 F250 Super Duty to get truck and 2021 315RLTS Reflection travel trailer level. 7, 9 or 11 hole. If its different than the standard 7 hole that come with a set-up, can the different shank come with the set-up and I pay the price difference or does the set-up come with the 7 hole and we must purchase the other shank completely separate?

In order to choose the correct weight distribution system shank length, you'll need to measure. In regards to the Blue Ox 13K TrackPro Weight Distribution System, they come with a 7-hole part # BLU27FR and 9-hole part # BLU59FR. The max drop for the 7 hole is 1.97" above the center of the receiver and the max drop for the 9 hole is 0.78" below the center of the receiver.
If you need a different shank for your setup we do have other options which I have attached below but they would need to be purchased separately.
