Most Popular Upgraded Pin Box for Toyota Tundra

I haven't had a chance to put it on my trailer yet it looks much stronger built a lot better than the factory pin box exited to use it on my short bed

Great product, wish I had before I broke my back window and smashed my roof. Fast easy transaction and delivered on time in good order

This item arrived much faster than etrailer said it would. It came by truck, and the freight company driver was very nice and made sure I opened the box before he left. I installed it myself with some help from my 15 year old son. We used our forklift tractor attachment to put it in place. The Curt Flex Air totally changed the experience of pulling our 5er. It eliminates most of the chucking, and acts like shocks on a car, so ride returns to normal immediately after a bump in the road...which the Flex Air absorbs most of.

Changed out my old pin box for a Curt Flex Air pin box. This one seems to be very heavily built and should last for years to come. Haven’t had a chance to pull it yesterday but am sure it will pull and perform great. Thank you etrailer for another great shopping experience.

Hannah did an excellent job of working with me to find the correct upgrades for my towing system. 5 stars got her. Tge package arrived with the king pin poking through the box and having deep scratches. I think it will function ok. 3 stars for those handling shipments and deliveries.

No bucking and jerking has made for enjoyable RV experience this year. One of the best investments I've made in our RV. prompt handling and shipping from etrailer made it even better!

Parts where on back order per information given by my 2 other vendors etrailer had it in stock and arrived on time before original ETA As a owner of a small business etrailer is great to work with and always helpful.

Sidewinder worked great for my short bed Ram. Be sure to get the matching wedge for your hitch. Thanks etrailer. I will be using you for all my trailer components

the fit was perfert. as you can see from the pictures is attached, i drilled a hole in the top to drain water that collects. i fabercated a cover to fit over the opening.

Best upgrade to the 5th wheel you can do. Our first cross country trip and I-40 beat the snot out of us on all the bridge transitions with the stock pin box. Immediately ordered this unit and now it’s like the trailer is floating behind us. I run 65 psi in the airbag. Solid unit and easy installation.

My wife and I are very pleased with our purchase of this product. We have taken numerous trips with our rig since installing it and what a difference it has made from the standard basic pin box. We no longer feel any chucking from starting off and stopping when towing our trailer. I figured it would definitely reduce it but it eliminated it completely. We tow with a one ton F350 long bed SRW and a B&W hitch. In my opinion It is not a DIY installation because of the sheer weight of the product otherwise I think that it would be. It is not a complicated item to install its just super heavy. In addition to my praise of this product, I would like to recommend the addition of grade eight hardware to be included with the product for installation. I think a few dollars more for the price should more than cover that cost. When it comes down to it the grade five hardware is sub standard for such a massive object in my opinion. It is supporting not only the weight of the pin box but the torque under load as well so for the purpose of safety, which is why we purchased it in the first place the hardware has to come off anyway to take off the old pin box. So why not replace it at the same time. My two cents worth anyway. I would definitely recommend this product to others who are looking to eliminate the chucking felt under a standard fifth wheel pin box.

Well, The hitch was to be delivered on the 23rd. Tforce the company you chose to deliver is located in the Philippines and after speaking to 5 different NON English employees I gave up. So I called the Tforce in Fontana Ca where the hitch is now. NO One answers the phone then after 30+ attempts a female answered and before I could complete my request she transferred my call to an empty line.

Freight co delivery estimated for Friday, arrived today. (Tuesday). Borrowed a tractor, dropped the old and lifted this monster into place. 12- 15/16 bolts (originally) 18 hole mount. Not sure if the height is correct for the bed, but will adjust it down if after the rubber bumper is inflated, if it doesn’t sit level. The bolt pattern was correct. better get help! From dropping the MFG lippert, to getting the thing lifted an bolts snugged up, about 45min. Will take a bit longer to attach the deadman switch and electrical box. Well crafted, definitely heavy. This should save my truck n RV from porpoising damage as I’m going over Bridges and bad roads.

We're so anxious to try out our new Curt TrailAir. Installation went smoothly, it looks great. We can hardly wait to experience the ride!

Smooths out the ride greatly, really pleased with so far. I removed the Air chuck and installed a tee with Gauge and air chuck makes it easy to monitor air pressure before traveling, one should note that these do bleed pressure down in few weeks that is pretty much normal for air bags of this type. I have a Dewalt cordless mini compressor and it works great to quickly & quietly pressurize before trip. I usually set my at 65 PSI

I think that this is just what the doctor ordered. I have not installed it yet, but this looks very much like what I need for my trailer!

Very great product, took the chucking and jerking out when towing my fifth wheel, would recommend it to anyone, wish I would have gotten it years ago.

Dramatically reduced chucking as hoped. There is more start/stop slop than I had expected but I'm guessing that is due to my trailer being at the top of the weight rating for the rubber block. I need to put a camera on it to verify my theory. All in all a huge improvement.

It's a great pinbox. Really helped with chucking and compatible with my Demco sliding hitch. Also no issues with delivery, was helped by Pam and Jessie. They are awesome people to work with.

I have had many coach's with this hitch, that is why I am changing out the one currently in the coach to this. UPS delivery sucks. Box was misrouted to another terminal after arriving at the facility near me. Caused an extra day's delay in delivery. When box did finally arrive it was virtually destroyed and driver claimed box showed up open and that they had to retape it this morning ING before delivering it.

Delivered intact.

Replaced Rhino with this unit on my Cedar Creek 311RL. It was straight forward and simple, but not easy for this old man to do it solo. Used the tailgate as my shop. Stuck the back up in the air and drove back to insert into the bracket. I then used the levelor on the trailer to line up 2 of the holes to insert the first bolts. I used a car jack near the pin to raise the 230 pound box into line up position to insert the other 8 bolts. Torqued it down and aired it up, then test drove it. Rides like a dream. Much softer on those in the tow vehicle and I assume on the fifth wheel itself. Service from etrailer was good. The advice and recommendations for my specific rig was a little off. But I was able to do research myself. Shipping was timely. Over all another successful etrailer transaction. Thanks to everyone.

Excellent buying experience. We were able to remove and install the new pin box ourselves. E-trailer’s videos were very helpful as well. Super excited to experience an improved ride.

Entirely better experience towing, my wife and I picked up our 1st 5th wheel toyhauler camper and towing it home it started jerking back n fourth, not knowing what the hell was going on she wanted to return it. I did some research and found this Moryde cushioned pin box and it’s super smooth. We’re both very happy and feel a lot more comfortable towing places.

We used to have a lot of slop with our hitch and that has lessened immensely since our purchase of the MORryde pin box.

Product was received as expected. Installation went very well. I am eager to try it out this week on the road!

Simple design, very robust construction, made a vast improvement in towing ride quality. Easy install by myself, Engine hoist, utility cart and motorcycle jack...ya I have "stuff". I will need to lower my B&W slide about 2inches to get back to level towing. Calculator that Gen Y has for selecton is spot on , I was a bit worried as my measured tounge weight was 2700 +/- lbs 22% of GVWR (14,400) was 3168 so I ordered the 4.5k model When hiched for the first time...indicator was in the middle of the green (perfect). Very happy ... next Im adding shock absorbers to see if i can smooth the trailer hop a bit more.

The benefits of an airbag hitch without the worry of air leaks. Drastically improves the the ride and drivability. Thanks Gen-Y and etrailer

I just completed a 2800 mile trip after installing the Trail Air Air Ride pin box on my Solitude 5th wheel. I was able to install it myself from the bed of my pickup using a hydraulic bottle jack to lift it into position. I previously made the same trip with the factory installed MORryde Cushioned Pin Box and the Trail Air provides a greatly improved ride. With the MORryde, I encountered several sections of concrete highway that set up a front-to-back oscillation which persisted across many miles. I didn't have that issue with the Trail Air. I didn't order the Flex Air model that also included the flexible block because I was concerned the added height of that pin box would have been a problem. However, after installing the non-flex Trail Air I've found that the other one would have also worked out if I lowered my truck hitch an inch or two. Also worth noting, this pin box is four inches shorter than the 1621 MORryde it replaced. However with a long bed truck I have no clearance issues and can still lower the tailgate when hitched up.

I'm pleased with the pin box. Put it on my 5th. wheel. The airbag gives us a better ride than any other pin box. Its a great product.

This Pin box was a Hugh upgrade from the Roto-Flex.The ride is amazing!!

Always a great experience ordering from etrailer
