Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000 lbs
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.

Curt Air Ride 5th Wheel Pin Box - Lippert 1621 & 1621HD - 21,000 lbs
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.

Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 or 1621HD - 18,000 lbs
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!

Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs
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.

Trailair Air Ride 5th Wheel King Pin - Fabex 730, RBW 7019 - 21,000 lbs
The pin box worked out very well. You still feel the bumps but almost no chucking. My wife likes to sleep in the truck with her head against the head rest, but she could not do that with the old pin box. The only thing that I had to do with the new pin box was drill out the holes because the old pin box had bigger bolts.

Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000 lbs
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!

Lippert 1621 5th Wheel Pin Box - 15,500 lbs
Hitch king pin box was a perfect fit and installed easily. I just finished hauling the trailer with it on a 5000 mile trip and it worked flawlessly.
First time using etrailer so I wasn't sure what to expect. But they were fast, efficient and keep us updated throughout the shipment. This was a replacement part for a customer shipping their cargo on us to Nome and it had to get here on time, very pleased with the service and follow through. Thanks Tom

Trailair Air Ride 5th Wheel King Pin - Leland 7920 - 21,000 lbs
The Trailair pin box is a great product. I installed it before a 700 mile trip and it does what it is intended to do. Etrailer was very helpful in selecting the correct pin box for my trailer. Thank you.
I just got the pin box, so I don't have it installed yet. It seems very well built. I wish it had a removable eye in the top so I could lift it with the crane that I have in the bed of my truck. No complaints though. Can't wait to try it out.

Curt Flex Air 5th Wheel Pin Box - Lippert Rhino - 21,000 lbs
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.

Lippert 1621 5th Wheel Pin Box - 21,000 lbs
The product is exactly as described and as shown in the pictures
When I got it, there was like eight or nine scratches the bracket that hooks to your camper that hooks to the plate the lip that bends over was bent up so I had to use a hammer to knock it back down and a couple other places where it was looks like it’s been dropped It’s far from his heart, but it don’t look the best.
