Eating Crow - the "new" Blue Ox Sway Pro
OK, so I will admit upfront that I was one of the first to warn people about the new design of the Blue Ox Swaypro hitch. I had tried to order the original design last year and all that was stocked w...

George...Thanks for measuring and posting...new thought is that the arc centers
are NOT on the same line...hmmmm...maybe a compounding effect...gotta noodle that
Good to hear you spent the time to set it up and that you got it right !
I'm old school rule of thumb...even drop
Agree that the height measurement does not always correlate to weight on that
corners tires
One aspect of even drop that is missed by so many is that there is a dialed in
proportion or ratio of weight. So many think or are unconscious that the front
vs rear axle suspension spring system are DIFFERENT weight ratings and that they
also have or may have different curves (weight vs drop)
My opinion is that the WD back to the front axle are for steering control and
avoiding an over steering condition (that would also be a snap transition). An
over-steering setup is very dangerous (jack knife) and tough to have the presence
of mind to do whatever (I'd say getting the trailer brakes on WITHOUT the TV
brakes). Used to have to manually initiate the trailer brake controller, but
with my current setup on the Sub, just touch the brake pedal without going far
enough to get the TV brakes to initiate
Height measurement just confirms that weight has been transferred. Not how much
Plus with some (GM in particular) their front suspension has very different
spring systems. GM has the bump stop touching in a null position (no added
weight). So WD'ing weight back to the front axle will have two spring systems
in play...so how much vs height????
All of these metrics are just ways to get you into the ball park. There are
many other attributes, both inanimate and the driver. Also assumes a stock TV
Folks adding a rear anti-lean bar without increasing their OEM front bar have
created a snap transition to over-steering condition
That snap transition happens when the outside tire rolls over, rolls over some
more...till it's traction limit has been reached. Some lower profile and wide
tread may lift the inside of the tread if their PSI isn't high enough to maintain
the tire's shape. Rim width plays in this
