Re: Weight Distribution Hitch for 4x4 Hemi with Quadralift pulling 3,200 lb trailer?

It doesn't matter if you have QL or the "regular" suspension...the WDH is still a requirement over 3500 lbs to insure weight is distributed to the front axel in a balanced way. The difference in height between "normal" and "aero" isn't all that much height. I personally wouldn't worry about it. If you set up your trailer ball height correctly...which makes the trailer ever so slightly nose high normally, the little bit of extra drop at the ball if "aero" kicks in just shouldn't go lower than level. You need to test for this while you do your trailer and WDH setup. (You can force into aero for your testing by going into sport mode)

I've always read that the trailer tongue should slightly below level when adjusted properly. I'm going to dig around and see what I can find.

Edit:
Found this in the Equalizer hitch manual:
Quote:
• Trailer coupled attitude: Attitude refers to the angle that the trailer is
tipped to. It is generally accepted that a trailer should be towed sitting
parallel to the ground, or with the front (coupler) tipped slightly
down. The front tipped too far up or down may be an indication of
improper trailer loading, or a need to adjust the ball height or weight
distribution settings.

Interesting. That exact same warning box with "mandatory" appears on page 561 of the '14 Cherokee (not Grand) OM but later in my OM where talking specifically about the GC (and not class I and II hitches) it says "recommended". Big difference.

Re: Weight Distribution Hitch for 4x4 Hemi with Quadralift pulling 3,200 lb trailer?

I bought a Blue-Ox Sway Pro WDH to tow my travel trailer with my GC.

Blue-Ox recommends disabling the air suspension before setting up the WDH, then leveling the trailer and measuring the tongue ball socket height. Then connect the WDH to the vehicle and install the ball so that it sits 1-2 inches higher than the ball socket height. This height is adjustable but the target goal is that the trailer will sit level when the trailer is hooked to the vehicle.

Attach trailer and then re-activate the air suspension.

I haven't done this as the trailer and Jeep are new to me but this all makes perfect sense and should probably be used with other air ride suspensions and WDH systems.

Blue-Ox SwayPro

Interesting...and contrary to what we do in the horse trailer world, for sure. Nose is always up slightly for stability as well as to insure that, um...liquids...drain to the rear.

The last bit is definitely a good thing.
