Hitch Ball Question

I use a WD hitch, sway control, etc. and have no towing problems but have a question.

I see some WD hitches with the ball tilted at an angle. What is the purpose of this?

What you are probably seeing is a WD setup where the ball mount is tilted to get the correct spring load on the weight distributing bars. Sometimes just setting them up level is all that you need, but other times that may not give enough spring effect to have the truck & trailer level. As you tilt it down, it puts more load on the springs and raises the trailer tongue.

x2. Also, you want the spring bars to be, roughly, as parallel with the frame as you can. If they are way off, that's why you pitch the head down. Every hitch I install gets pitched down some.

The angle of the hitch ball is used to fine-tune the weight distribution.

Step one in adjusting the hitch is to get the spring bars tight enough to remove 40% to 50% of gross tongue weight off the rear axle.

Step two is to adjust the angle of the ball so that about the same percent of tongue weight goes to the front axle and trailer axles

Ideal setup will result in 20% to 25% of the tongue weight going back to the trailer axles, and another 20% to 25% of the tongue weight going to the front axle of the tow vehicle, and 50% to 60% of the tongue weight remaining on the rear axle.

So with 1,000 pounds tongue weight, adjust the spring bars so you have 500 to 600 pounds of tongue weight on the rear axle. Yes, this may take a couple of trips across the scales. After you have the spring bars right, then mark them or otherwise know exactly how to get the same tension when you hook up later.

When the spring bars have the right tension, then note the weight on the trailer axles and front axle. With 1000 pounds total tongue weight, if the weight distributed to the trailer and front axles is not 200 to 250 pounds each, then work on the angle of the hitch ball. On mine, the spring bars are fine, but I still have too much weight going to the front axle and not enough going to the trailer axles, so I've still got some adjusting to do.
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 EcoBoost SuperCrew.
