Choosing the Correct Rise for Weight Distribution Shank

Question:

I bought a 2016 Expedition EL. Need to buy a new shank for my Reese trunion style weight distribution. Had a Ford van before with my current tailer. The height from the top of the hitch ball to the ground was 24.75 in to maintain a level towing vehicle and trailer. Need to maintain that overall height with the expedition. The height of the 2 in x 2 in receiver on my expedition is 20 in from the measuring at the top of the receiver. The current shank does not get me my desire rise. What do you recommend? Here is what I think... Reese Weight Dist Shank - 12-1/4inch Long - 2inch Drop to 6-1/2inch Rise - 1,500 lbs TW Item # RP54970 Or Equal-i-zer Weight Dist Shank - 12inch Long - 7inch Rise, 3inch Drop - 600 to 1,400 lbs TW - EQ90-02-4100 Or Other?

To choose the correct weight distributing shank, you will just need to determine the height of the top of your Expedition's hitch receiver as well as the height of the bottom of the trailer's coupler. The difference between these two measurements will be the rise (or drop) that is needed.

You did mention the height of your trailer hitch receiver at 20 inches in your question. For the most accurate measurement, I recommend also measuring the height of your trailer tongue when it is level. But using the information you provided, we can assume that since the 24.75 inch trailer hitch measurement on your old Ford Van was sufficient, that you will need a rise of around 4-3/4 inches on your Expedition.

The Reese Weight Distribution Shank # RP54970 referenced in your question with a maximum rise of 6-1/2 inches should work great to keep your trailer level and is compatible with your Reese trunnion-bar weight distribution system. It has a gross towing weight capacity of 15,000 pounds and a tongue weight capacity of 1,500 pounds.

The Equal-i-zer Weight Dist Shank # EQ90-02-4100 you mentioned is designed to work with Equal-i-zer systems so it may not be compatible with your current setup.

I have attached a video demonstration of this shank as well as a helpful article on choosing the correct ball mount, which will be the same procedure as choosing the correct weight distribution shank.
