King Pin Tripod

King Pin Tripod Hitch Cup

After unhitching your fifth-wheel trailer or RV, steady it with the Ultra-Fab tripod stabilizer. Simply position the tripod beneath your trailer's king pin and release the chain that holds the stabilizer hitch cup in place. The hitch cup will rise and surround the king pin. Reattach the chain by hooking a bottom link around the bracket on the tripod leg. Now use the handle on the hitch cup to fine-tune the height of the stabilizer. Turn counterclockwise until the cup is sufficiently snug against the fifth-wheel king pin. Once everything is in place, insert the included padlock and your trailer will be stable, supported and secure.

Quickly and easily stabilize your unhitched fifth-wheel trailer with this sturdy steel tripod. Adjustable hitch cup makes setup a snap, and the included padlock provides an effective theft deterrent.


I did not do enough research and wish I would have bought an easier to use product. My son-in-law has a stabilizer that works much better.


The ultra fab fifth wheel king pin tripod works excellent the leveling jacks on my fifth wheel were leaking off and the tripod did it’s job I am very pleased with this product and have told other fifth wheel owners about itOne of the people I told but one I don’t know if the other people have yet or not but I would recommend it to anybody


It works, but a bit of a challenge to set up & install. It’s like a puzzle.


Delivery was incredibly fast( within a couple days!). Like other reviews, I was very please how good the stabilizer minimized movement on our 5th wheel camper.
I have made several purchases from and have been satisfied each time with prices,product and speed of delivery!


Cannot say enough good things about etrailer. While away for the winter in Arizona I ordered a tripod for our 5th wheel. By mistake I switched mailing and billing addresses around and did not notice it until checking tracking. With one call to etrailer everything was taken care of and received the package in a few days. Thank you for your outstanding customer support!
The tripod arrived well packaged and is of excellent quality! I recommend this item to anyone who is looking for a well designed tripod. I have purchased many items from etrailer in the past and am still amazed at the customer service!

Its been a year and the tripod looks as good as new. This is a good product and a great choice. Highly recommend and etrailer is a great company to do business with.

Very easy install product works great in windy conditions & washer & dryer running also walking around. Added the 8” extensions so the tripod can be fully extended for the best results.


I'm giving it 5 stars because it came on the day they said it was going to get to me. I haven't opened it yet ill do that in a few weeks when we are going camping. If anything is wrong with it I'll get back on and let you know

This is working our just fine the camper doesnt move around as much when doing laundry

Looks sturdy. Well built. Took the wobble out. Good for stabilizing. Came with lock. Glad I was able to purchase. Shipping was fast.


The Product is excellent however the extensions and the foot plates are not quite right and had to be persuaded to go together. It other wise worked well.


Very good product, light weight but strong, easy to use and does a good job. Used for a month in Florida and helped stabilize our unit.

Works great, easy to use.stabilizer does help.

Very well made.


Order came in and was wrong one...Second one came in and there wás no return shipping label like there was suppose to be,......


I have not owned a fifth wheel until now, so alot of the equipment necessary is rather new to me. My son-in-law is the GURU when it comes to this and he was impressed w ith the quality & price for the tripod stabilizer and the slide-out stabilizers Wheel chocks will also serve their purpose. I was very impressed with the speed in which I received all this equipment. I will be sure to use you in the future for further purchases.

Everything is still in grerat condition. These items are used on our fifth wheel that is located on the Gulf Coast of Florida next to salt water and they have held up remarkably well.

Excellent product we use with our Jayco 5th wheel. It stabilizes the unit nicely when it is parked.


Since the bolts for the feet are not in the package. Im not capable of putting it together.

It is very unfortunate that you are missing these items. I have sent this information over to our customer service department for them to get in contact with you.
-- Etrailer Expert Katrina B - 04/25/2022


This is a good product, however it has some drawbacks. My trailer has the trail-aire air ride fifth wheel pin box. This stand doesn't work very well with it. There isn't enough travel in the adjustment bolt to compress the jaws of the pin box. Without that, the stand doesn't really offer much support. I have found I can let the air out of the bag, and jack the trailer up slightly higher than where I want it, and then let the trailer down on top of it. Once the trailer is down on the stand and level, I put some air back in the bag just to put some weight on the stand. I have used it only twice, I will figure out the best method as time goes. Note: I suggest you order the extensions. There are times where you will need the extra length.


Fast shipping.. product was as described. I will defently use Etrailer again.


Very solid product. I needed the extension legs for my particular 5th wheel not a problem to install them. Etrailer costermer service was very helpful to guide me to the right products I needed.. I would definitely recommend this product!


Nice product would recommend make sure to purchase the extensions with your order arrived in a timely manner great job etrailer will be ordering again from you

Works great helps stabilize the unit

Just wanted to let people know I have ordered other products from etrailer before and each item has met my expiations and the price is the best part the lowest of any other site I looked at that's why I will keep coming back.

We use it all the time it helps stabilize the 5th wheel when its windy out and when were walking around

I ordered this stabilizer for my Keystone Raptor fifth wheel. The stabilizer arrived very quickly and it was obvious that it had been returned by another customer prior to it being sent to me. The box was held together with a ridiculous amount of tape and there was no styrofoam left inside the box which allowed the stabilizer to destroy the box while en route to my house. The stabilizer is of good quality but, it is too short for my fifth wheel. I ordered the extensions, which I would highly recommend for this item. Together with the extensions, the stabilizer works very well.


I purchased the UF19-950001 rv jack after watching a video that showed how easy and fast it was set up. I was having to use blocks under my rv jack and adjust the chains on the bottom of the legs for height . This process took for ever.The UF19-950001 sets up in just a few minutes just like the video showed.


This works great at stabilizing the front end of the fifth wheel. I will they made a small version for the back end of the trailer as the side sway of the back end could definitely use this level of support.


This works great, would have given a 5 star rating except the cup at top is too deep for our hitch pin. Have to carry some large washers to lessen the depth.

Works well, still need to add washers as cup too deep for my king pin!

Good product - would have liked it to have longer leg adjustments for some higher level positions. When blocked up it works well.
