Not a direct answer, sorry. I've owned both the Blue Ox BX1500 and the Equal-i-Zer 10K hitches. I weighed all components of each assembly including head, ball, shank, bars, brackets and fasteners. Equal-i-Zer weighed 96.8 lbs. Blue Ox weighed 79.0 lbs.
My goal was to determine how much was added to tongue weight by each system. I gained 17.8 lbs. CCC and a higher rating by switching to the BX.
The BX head is lighter, and so are the bars. I no longer have my notes, but would estimate the BX head/shank is about 7-8 lbs. lighter than the Equal-i-Zer.
