As long as you don't have an inverted coupler with the 800 lb SC kit, you'll be fine with the Reese SC. If you have an inverted coupler, the 800 lb kit won't work. The 1400 lb tongue weight kit will but the brackets reach way down to the spring bars taking up a good bit of ground clearance. I almost ordered the 800 lb kit before I found this thread from years ago.

I've seen some old Equalizer hitches both 4 point and 2 point and wear on the brackets and spring bars is surprisingly minimal.
The Steady Flex looks like it should work very well.
