To make things easier for those looking for the tools list: For install without the hitch ball preinstalled: * e2 Owner's Manual * torque wrench - 250 ft-lb capable * torque wrench - 430 ft-lb capable * ratchet wrench * 1 1/8" wrench or socket * 1 1/16" socket * (2) 3/4" wrenches or sockets * 15/16" wrench or socket * measuring tape * pencil * 1 7/8" thin walled socket * 1 3/4" wrench

4005 - 3925 = 80 not 75. Same on Rear - 3650 - 2795 = 855 not 845 as your summary shows. The e2 distribution shows load being shifted to trailer axles, but only shows total load. I would have liked to see two scales on each trailer axle - to show that you are overloading the front trailer axle when not level, and with the e2 you are level and distributing the load equally back onto both trailer axles. Do this again to show if the e2 is distributing the trailer axles as well.

I would love it if you would have done one more test, after equalizer hitch, put a little air in, see what happens

I have the top of the line equalizer hitch and it works well when I’m on a nice smooth road, but when it’s rough, the road cause’s bounce and just gets a little squirrelly. I plan to get the lift bags to give it a little more support. It seems on 1/2 ton trucks, it’s just necessary to add some support?

Be sure to take into account how much stretch those cables have before they will disengage the plunger. The coil tension will not provide any ability to achieve that unless the cable is nearly straight. So stretched length adjustment is critical! 😊. I have seen many that will not provide any braking unless the complete hitch fails and drops off the tow vehicle.

Hi, can you confirm the overall combined weight increases when using the WDH compared to using no other devices for levelling vehicle??

Where did you get a size XXXL pink bunny costume? Awesome!

Wow- Very professional video! well done!

Thanks so much for the research and video! Leaves me curious, weight distribution hitch seems to be the way to go. Does that affect the 60/40 rule though?

Great video!

Angle set bolt needs to be tightened on my E2 every 200 miles or so. Always so comforting

Airbags do not have any leverage and cannot replace the weight taken off the TV steering axle when pulling a trailer. A PPP WD hitch, (Hensley or ProPride) moves the fulcrum point from the ball to the TV rear axle, 37 years of using the Hensley Arrow absolutely no trailer sway ever, with a level fully loaded for camping rig. i.imgur.com/9aECWOt.jpg YMMV

Helpful video. Having a downloadable PDF of the measurement table would be really useful to add to this video.

How is this product even certified! Chains that are too long and dragging would be extremely dangerous and tethering them up in the "chain up " or twist ties or rope or any other way is extremely dangerous. if the trailer were to disconnect it simply would tear such adjustments apart and the tongue of the trailer would end up in the asphalt or !! ...chains are supposed to be just the right length and criss crossed in order to support the tongue OFF the ground in the event of a disconnect !

What is the brand and type of grease you are using in this video?

I've used the chain WD hitch for years on a construction trailer on short wheel based vans with the friction anti swaybar. On Long wheel trucks I did not need the sway bar. Got use to the chain adjustment fairly easily. When setup properly towing is a pleasure. I just bought a new enclosed cargo trailer and the old Huffy would not fit. I would need to cut holes in the floor to link the chains up. Bought a newer style WD hitch setup called a Curt True track #17499 WOW what a pleasure to tow with this! It has square spring bars that allows shorter placement of trailer frame clamps. And this system doesn't use chains. So the anti sway is built-in to the product.

A. Couldn't the same affect be had by moving the trailer load back on the trailer?

Good, helpful info.

Thank you guys for the clarification. Very helpful 7 years later 🤗

Next time show us how to hook the bars up the sway bars

Hey guys, what about vehicles with self leveling suspension, Landrover lr3/4 etc?

If your chains are so long that they drag or are close to the ground they are too long to use, if the tongue comes loose it will dig into the asphalt and flip the trailer or the tow vehicle, use safety chains that have about 3" of sag so they will cradle the tongue like they are supposed to do.

Ok you have a good ride height now, but now your trailer axles have more weight on them which could wear faster on the trailer and cause more blow outs and put more stress on the tongue which could cause it to crack.

Did you know if your airbags are right above the axel, that is the weakest point of your pickup frame, and it is going to bend right there above the axel because there is a multiple amount of pushing force down at the hitch it is like adding a cheater bar to a wrench to get more force to break free a bolt.

Yes, but most people are interested about using both systems. Why not bring that part up? I don't know many people that just one one vs the other, most realize the importance of the WDH systems, but it would be nice to see a summary of the advantages/drawbacks of using both systems in tandem (and the best way to set them up if doing so)

Surely if you loaded the trailer properly with the load over the axles and 10% of the gross weight on the tongue, you would have a much more balanced and safer combination. Why would you put so much load on the tongue and not on axles where it's meant to be?

So heavier needs more spacer washers or less?

Absolutely hate when my coworker tells ppl "if you have air bags you should be fine, you dont need a WD"

Would love to see what happens when combined! Great video!

Just load the trailer correctly, problem solved 😂

The place I bought my camper from set up the weight distribution hitch. Everything sits nice and level, however when I am connected to the trailer the distribution bars have little to no weight on them. In fact I can move them quite easily with the full weight of the camper on the truck. do I need to to raise the brackets that the bars set on?

Just enquiring if Jason calculated the load reactions on the chassis frame verses the Frame RBM and factor of safety needed and also on the differential housing with the air springs were inflated to 55psi which is generally 5 to 10 psi under the maximum pressure you see on a loaded vehicle fitted fully designed for air suspension.

Airbags do just what they are designed to do, take away the squat. Nothing more nothing less. Weight distribution hitches are far more affective at fixing the transfer of weight that adversely affects the safety of towing a trailer. Airbags are a waste of money

I’m so glad I found this video. In General, having your RV dealer install these doesn’t mean it’s done correctly.

Wish I could get the frame bracket to quit moving on mine..smh.. I really don't know why you guys don't make the inside link plate thicker so it doesn't bow. I followed the book exactly as the tightening procedure recommended and torqued to spec with a $500 Snap on torque wrench and it still bowed and moves an 3/16" either way on one of the brackets..

Thanks! Quick, informative video. One question: I’m leaving my trailer hitches for three or four days while I travel. Is it ok to wait that long to lubricate? Thank you.

I would have liked to see a combination of say 30psi or so in the bags with the weight distribution system. I replaced my rear leafspring suspension with a 4-link and airbags with a auto-leveling valve so my suspension automatically adjusts the pressure in my bags to keep the rear of the truck at the height I chose(level front to rear empty) from any weight adjustments, the same as a semi. Due to this I really wonder what kind of weird effects would come out of using a weight distribution hitch, if any.

very helpful

Should the measurements and adjustments of the Weight distribution hitch be done before or after the bed of the truck is loaded with contents? Firewood, chairs, coolers. I try to keep things in the bed vs in the camper.

Great video even at 7 yrs old... now it would be nice to do an updated video using both WDH & Airbags

I had this system installed by a dealer but when I arrived home and started unhitching, I just could not remove the spring bar on one of the sides. I had a large wood block under the tongue jack and I literally used the whole jack length and had both my vehicle and the trailer lifted at something like a 25 degree angle to the ground, and yet there was still tension on the bar. I ended up having to hammer the bar out of the L-bracket with a big hammer, and after I did that, the rear of my truck just slammed down hard to the ground. I am not sure what the dealer or I did wrong, maybe someone can help.

Great illustration. Thanks for the work. I realize this is an older video but still very relevant still.

love the scientific approach, very helpful, thanks

I was just about to buy air bags for my truck to tow my trailer. Thank God, I saw this and thank you for this information and effort to bring it to a larger audience. Very much appreciated. Thank you.

Superior content fellas. Thank you so much for the additional effort of adding the graphics with the weights! It was so easy for me to pause while multitasking compared to others who auction off the numbers... AND NOW A TWO FIFTY!!!! Also I was starting to get a little worried about Jason since he wasn't speaking, he's good ;)

Excellent video, Thanks guys.. I now understand my airbags on My 2015 TRD offroad are not even needed now when towing my trailer, (actually they are the wrong approach) I will only use the Weight Distribution hitch, this style hitch makes a HUGE difference when towing. From Slightly scary to NICE Controlled ride. I do use the Airbags when hauling loads of wood stone etc. in the Bed to level it out.

I had the system fitted oct 2022 by the caravan dealer after using the H/R WDH before . Must say its a big improvement over the Hayman Reece WDH. One thing tho is it normal fir the friction points on the L bracket to show signs of a brown colour ( rust)? I rang my dealer and he said its ok but do not put anything oner the friction pads like silicon spray/ wd40 ect

Tks guys, I’ve got a weight distribution hitch for my RV but was thinking I might need air bags too. That might be for fine tuning. Great video.

I’ve had my e2 for two seasons now and it has been nothing but disappointment. The left side L bracket won’t stay tight and I’ve had the bar come off twice. I’m not sure what’s going on but I’ve torqued every thing to spec. I have the thousand pound bars and I’ve been told I need the 1200 pound bars because of the length and weight of my trailer. I get a lot of bounce and barely any sway control.
