I can tell you how to easily determine the correct over/under conversion kit for your 2017 K-Z Sportsmen Classic 180THT, though we would not be able to verify a specific fit for any trailer. It's easy to determine the correct over/under lift kit though because all you have to do is measure the diameter of your trailer's axle.

- 2-3/8" Round Axle: Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00

- 3" Round Axle: Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00

I have added links to the instructions for you to check out as well.

To drop the front of the pin box and thus lower the front of the fifth wheel, you'd need to RAISE the pin box, not lower it. Lowering the pin box would raise the height of the fifth wheel at the front. If you have an available set of holes at the…

If the leaf spring stack is currently attached below the axle, which is what it sounds like, then you can use an over/under conversion kit. If the axle is 3 inches in diameter then you can use #K71-385-00. If the axle is 2-3/8 inches in diameter use…

You said your axle is 2.5", however that is not a typical size. I suggest that you remeasure the axle, and verify that it is 2.5" and not 2 3/8". Measuring a round tube can be difficult to get a accurate measurement, you could use…
