The item you selected, Reese Weight Distribution Shank, part # RP63971 does have a lower drop than part # RP54970, but you will need to measure to determine which shank you will need for your towing setup.

To do this, there are a few steps involved. First, you will need to measure from the ground to the top of the receiver on your trailer hitch. Then, while your trailer is not connected to the vehicle and is on level ground, measure from the ground to the bottom of the trailer coupler.

Now you will need to calculate the difference between the hitch height and coupler height. If the height of the coupler is greater, then the difference will be the rise needed. If the hitch height is greater, then the difference will be the drop needed.

With part # RP63971, the maximum drop is 6-1/2 inches when used with round bars, and 4-3/4 inches when used with trunnion bars. If you calculate that you need a drop of 6-1/2 inches or less, then part # RP63971 will work great for your towing application. If you find that you need more of a drop, you will need a different shank. If you need a greater drop than 6-1/2 inches, I would recommend the Reese Weight Distribution Shank, part # RP3344, which has up to an 8-5/8 inch drop when used with round bars, and 7-5/8 inch drop when used with trunnion bars.

I have linked an FAQ on ball mount height below and a video that shows the measurement and setting up of a weight distribution shank and and ball mount. I have also linked an FAQ video on weight distribution systems.
