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 adjust the height of the stabilizer hitch cup so that it surrounds the king pin. 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 your trailer will be stable and supported.

Quickly and easily stabilize your unhitched fifth-wheel trailer with this sturdy steel tripod. Adjustable hitch cup makes setup a snap.


I purchased this for a 2021 Grand Design 31MB 5th wheel. The King Pin tripod along with the X-chocks I purchased from e-trailer were a perfect match/fit for our 5th wheel. We immediately noticed the difference with these installed just as described in the video on e-trailers web site. Thank you e-trailer for your awesome customer service and abundant information for items when making a decision for purchase!


I am quite satisfied with the quality and functionality of this product. However, the product brochure and other information about the product indicated an appropriate security padlock was included with the product. I didn’t receive such a padlock. I’ve checked at Home Depot, Walmart and Gibson’s and have not been able to locate a padlock which fits in the hitch cup. Can you assist me in securing a padlock which fits? I am attaching a picture of the hitch cup with pre-drilled holes for the padlock. Thank you in advance for your assistance.

Thank you for your review. Unfortunately the padlock does not come with the Ultra-Fab Economy 5th Wheel King Pin Tripod Stabilizer any longer. You can add Replacement Padlock and Keys for Ultra-Fab Tripod Stabilizers part UF19-001022 to lock the tripod cup to the king pin. If you would like to purchase a padlock at the hardware store the holes are 1 apart so you would need padlock that is 1 wide.

My order shipped on time, as promised but the package arrived damaged with missing parts.I called etrailer and talked to Carol,I sent pictures and after verification Carol sent me a whole new 5th wheel stand.The damage occured by the transport co. Who taped both ends of the box but left mutiple holes in the box where some parts were missing.I was surpised the carrier even deliverd the package that damaged, they should have taken care of it, by replacment on their own. The box was sturdy and proper for the product but was crushed during transit. Carol sent me out a brand new complete one right away instead of just the parts that were missing. I have used etailer for several rv parts and I will continue using etrailer in the future, they stand behind their product after the sale...thank you etrailer and Carol.


Packaging was horrible and instructions were very vague. Had to figure it out on my own.

Sometimes with these type of products the manuals are less than ideal. I recommend watching the video review listed below.

simple to install under your king pin on the 5th wheel the finish fit welds simple to carry and stow


Ordered this product to provide more stability in our 5th wheel, as it was quite wobbly... Packaging was damaged, both exterior and interior box. The retaining pin for one of the feet was missing and the the exterior box had been taped up where the damage was. Won't be until after the third foot is attached that I will know if it provides stability to the front of trailer.

I will have our customer service team reach out to you.

Still working good. The only thing that I noticed on this is around the top were the legs go into the top there is rust and paint flaking off. We full time so it’s been from Cali to NY in the weather all year.


I ordered the tripod just to get some extra stability on my 5th wheel camper. As soon as it came in I put it on and it made a HUGE difference! The front end of my camper used to have a little wobble to it and didn't feel very sturdy but now it feel 100 times more stable. I haven't had the tripod very long so I can't comment on weather or not it's extremely durable but it seems to be very well made.


Easy too find, Easy to order, Arived promptly Exactly what I ordered And exactly what I needed.


You did me great!!!
Great service and
I am grateful.
Thank you!


Light and easy to use. Thanks e-trailer.

Excellent. Really helps stabilize my rv. Recommend to anyone with 5th wheel. Also great security lock.

always great deals and shipping easy tr ans


The tripod stabilizer is easy to set up and stores easily in original box. It definitely makes a difference as far as wiggle and shake inside the coach. A fifth wheel needs support under the hitch when parked, there's too much overhang past the stabilizer feet on the main frame of the coach.
I feel the unit could have been a heavier built to take more weight but I have had it tight and it held!

The stabilizer offers good value for the money. Still working well, havent used the extensions yet. Etrailer is a good company to do business with.

Makes a huge difference in reducing trailer movement and vibration. Heavy duty enough to get the job done. Light enough to not be a bother.


My 5th wheel was constantly shaking when walking inside the trailer. Once I install this "Ultra-Fab Economy 5th Wheel King Pin Tripod Stabilizer", the shaking stopped. I could not be more happy with this product. I highly recommend this Tripod.

I am very happy with this product, I would recommend this Tripod to everyone that has a 5th wheel.

The tripod stabilizer works great and sets up easy.wish we would have bought it a long time ago.
Emily was very helpful .


Works great


Good product at a great price. Simple to setup and a noticeable improvement in stability with other people moving inside the camper.


Easy to setup and install


It heavy duty and works great to stabilize my 5th wheel. I purchased the ball assy so I can use this with my Anderson hitch setup. I also had to purchase the leg extensions so it would work with my 2018 Genesis Supreme 28CR Toy Hauler. The negative is it's heavy and awkward to store for travel. It does not come with a travel bag. I carry it in the back of my truck due to the sharp edges on the foot pads.


The process was fast and easy. The young assistant answered all the questions and followed though. Alway love doing business with you.


I like etrailer because they sell you exactly what they say they're going to sell you, at a very reasonable price. If you're in doubt about anything they have a video that will show you what you need to know. And if you still have questions you can call them and they will have the answers. However you access them they have exactly what you need.

Still works great. Thanks

I have been very pleased with the way this stabilizer has worked. My fifth wheel seems to be much more solid with this stabilizer on it. It helps eliminate a lot of the bouncing that I could feel before when someone was walking around inside. Only complaint is that the lock that came with it would not fit. It was impossible to get it to lock because it just wasn't long enough. I'll have to either buy another lock that is bigger or hope no one steals it while I'm camping!


Stabilizes the trailer. Have only used it on 1 trip. We'll use it in Tucson this winter when we live in the RV for 4 months


Easy to set-up. Really helps stabilize the RV. Wish it came with a storage bag.
