Stiffer bars for Blue Ox hitch?

Just an fyi. The head on the Blue Ox is not adjustable like the Equalizer hitch. Tension and weight transfer is determined by the chain.

Not sure about that.

HERE is a manual for one of the BlueOx versions.

Page 5 mentions..

"8. Position head assembly on shank. Slide head up or down to the nearest bolt hole alignment
position which corresponds with the “TARGET” ball height determined in Step 4 and Insert (1) ¾” x
4.5” HEX BOLT item #4(see Parts Listing pg 13) into bottom hole of channel.

9. Place four (4) hardened washers item #7(see Parts Listing pg 13) on pin item #6(see Parts Listing
pg 13) and insert pin into the unthreaded hole in the upper portion of the head channel. The
number of washers may have to be changed later.

10. Rotate head up until pin head touches shank, the hitch ball should be nearly vertical or tilted slightly
rearward (adjust number of washers under pin head until you get the desired angle) and then place
(1) ¾” x 4.5” HEX BOLT item #4(see Parts Listing pg 13) cone washer item #8(see Parts Listing pg
13) and insert into upper oval hole of channel through the corresponding shank hole.

11. Place a second cone washer #8(see Parts Listing pg 13) on upper ¾” bolt and then thread ¾” hex
nut item #5(see Parts Listing pg 13) only finger tight to both bolts. Then insert 5/8” bolt item
#18(see Parts Listing pg 13) into bottom hole on channel and tighten against shank, the WD head
should then move upward until the pin head contacts the shank then turn the 5/8” bolt an additional
1/4-1/2 turn."

See parts number 6 and 7 in the pix..

To change hitch ball pitch (and the angle of the bars), you add or remove shims (#7) from pin (#6).

The top hole of the hitch head should have a "slot" instead of round hole, the slot allows the adjustment to be made to the pitch.

Not sure which Blue Ox hitch the OP has but I suspect they should be similar for this adjustment.

Since OP had to move the hitch head on the shank they may have missed or lost shims in the process which would result in the ball to pitch towards the vehicle which will point the bar ends up towards the trailer frame..
