Video Transcript for Review of Lippert Components Fifth Wheel King Pin Parts - Replacement Shock for Trailair - LC177223

Ellen: Hey everyone. I'm Ellen here at etrailer.com and we're taking a quick look at the Replacement Shock for your Trailair Air Ride, and also your Flex Air Fifth Wheel King Pins. So if something happened with that original shock, it got damaged, bent, broken, what have you, this is a direct replacement part from the manufacturer.Now it used to be that there was a big sticker on here to let you know how much to inflate the airbag on that King Pin. There is still an indicator, but it's a bit harder to see, and I'll show you that in just a second. But I just want to point that out that this is still the direct replacement part, but it does have a different way of showing you where to fill up too.So you want to make sure that you inflate it to that line to make sure that everything is working properly. So it's just etched into the metal now.

So inflate to this line and then an arrow going up to this etched in spot. I am not a huge fan of this change. I mean, the nice thing about it is that it can't ever rub off or get damaged because it's etched into that metal, but it's really hard to see. So, might want to add like a paint marker or a little bit of paint to this, just to kind of fill in those lines and give you a clearer mark. That would maybe be something that I would do.

But overall, it's kind of up to you on what you want to do there.This does work for a lot of different fifth wheel pin boxes. To see the complete list of compatible part numbers, you can check out our website here at etrailer.com to make sure that this does work for you.But again, it works for your Trailair Air Ride models and also your Trailair Flex Air models, so it just helps to keep your airbag from breaking down, make sure that you keep everything at the right level and so on.So whenever it's at its compressed length, it's about 8-3/8" long and whenever it's all the way extended out, it's 11-5/8" long. So right now we have it all the way extended and that's going from the center of the attachment point, to the center of the attachment point at the top. So that's going to be our distance there. And again, when it's fully compressed, it is 8-3/8 inch.But that's pretty much all there is to it for our look at the Replacement Shock for your Air Ride or Flex Trailair King Pins.

I hope this has been helpful in deciding if this is the right replacement part for you. We do have a lot of other replacement parts available here at etrailer.com, along with a lot of other accessories for any of your towing needs. So check us out.Thanks for watching.

The visual appearance was not what I was expecting. The paint was very scuffed as shown in the pictures. It appears to have been in your inventory for a long time an potentially handled roughly. Hopefully it will be functionally fine.

I will have customer service reach out to you.

Perfect replacement shock absorber for the Flexair hitch on our Redwood fifth wheel. We had a mishap that left the original with a bent case and it was difficult to set the pressure in the air bags as it would often stick. Simple to install and has my has my hitch back to proper operation. Ordering process was easy, part arrived on time in perfect condition.

The replacement shock is still performing as it should.

I ordered replacement shocks for my trailair hitch. they arrived on the promised delivery date and were identical to the OEM shocks. The ride of the trailer improved, the old shocks were 10 years old.

by:

The shock works great, but the arrow etched into it appears to be a different size than my original one and therefore inflates the bag way too much to even come close to the top of the arrow. I have since just put a new mark according to my original shock arrow and inflate to this new line

I chose Etrailer parts because they had a good selection of high quality replacement parts for my AirRide 5th wheel hitch (and everything else I need for my truck and trailers). My original equipment was very old, and I expected it to be impossible to find a replacement that fit, but George at Etrailer had them NEW. I installed the parts a year ago and I have been very happy. The quality is clear after a year of hard use--the parts still look and perform like new (better than the rest of the trailer!). The pictures show it ... the shock absorber and air bladder and steel yellow valve stem still in top shape with almost a thousand miles on them. So glad I have Etrailer a try!



- LC177223
by:

Easy to replace, and made a huge difference on the comfort of the ride in my truck. Noticed that I needed a new one when it took extra air pressure in the air bag to raise the shock to the proper height. Wish I had noticed that earlier. Well worth replacing, and the service from etrailer has always been top notch. Got a B&W fifth wheel hitch earlier, and that is completely amazing!! Worth every penny!

I have not had a chance to install my new shock absorber. After I have installed it and tested it, i will write a better review. I was very happy with the order process and the delivery.

Needs to have the full pressure marking like the original shock has. Would make it much easier to know when you are getting the proper amount of air in the bladder.

I replaced the shock on my Flex Aire pin box that had been damaged due errant parking. It was a diprect replacement first all, two day shipment, simple, easy to install and I feel confident of the future performance. This a great set up too, smooth riding all the way.

  • Replacement Shock Recommendation for Trailair Pin Box
    Sounds like you are looking for a replacement shock for the Trailair pin boxes. For that you would want the part # LC177223 which is exactly what you'd need.

  • How to Know It's Time to Replace Shock of Trailair Pin Box
    Shocks slow the rebound and movement of the two parts they are installed on. So if all of a sudden your Trailair pin box becomes much harsher when at the correct air pressure for your trailer that would indicate that the shock is bad and in need of replacing. Or if it looks psychically damaged as well.

  • Trail Air Pin Box Shock and Air Bag Replacements?
    What you're experiencing is exactly what a Trailair is supposed to suppress and would tell me that some of your components are worn down. While some chucking is inevitable, your shock shouldn't really move freely like you're suggesting, so replacing the shock would likely help fix some of your current problems. I can't say that I've seen a Trailair pin box that has a 24,000-lb capacity; I've only seen them go up to 21,000-lbs. If you do end up having a 21000-lb version opposed to a 24000-lb...

  • Can Trailair Flex Air King Pin be Replaced or is New Pin Box Needed
    The bolt-on section that has the king pin on the Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 # LC369535 is not a part that is replaceable, likely because it is so vital to the integrity of the entire pin box and its 21,000 lb capacity. So while it may not be the news you want to hear, in order to ensure you are able to tow safely you will need to replace the entire Trailair pin box entirely.

  • If Lower Plate of Trailair Pin Box Replaceable
    The lower plate of the Trailair pin box is not replaceable but if you were in a situation where it would need to be replaced you'd need to replace the entire pin box. There isn't an exact figure or dimension that gets checked to know if the lower plate is bad or damaged but you'd just have to look at it and look for signs of wear or damage to the king pin and plate.

  • How the Shock Works on Trailair Air Ride and Flex Air 5th Wheel King Pins
    The Replacement Shock for Trailair Air Ride and Flex Air 5th Wheel King Pins, part # LC177223, is a shock that also serves as a dampener for kickback. What that means is this shock works in conjunction with the king pin's air bag to absorb road shock from bumps. This keeps the air bag from bursting. Then, after everything is compressed, it dampens the kickback (upward rebound) from the air bag to its natural position. This position is not fully extended like a traditional air bag suspension....

  • Is Uneven Shape of Trailair Pin Box Air Bag a Problem
    Thank you for the photo of your TrailAir pin box's rubber air spring. The shape/position of the bag are not necessarily an issue. Just in case I do suggest that you check that your air bag is inflated to the correct pressure. There is a simple way to determine the correct pressure. Hitch your trailer and them slowly add pressure through the air bag's Schrader valve. Add pressure until the two black arrowheads on the yellow sticker on the shock are just visible.

    There are a couple different Trailair pin boxes for the 18,000 lb capacity. There is the Flex Air like # LC328492 and the Air Ride like # LC179879. With either model, the air bag should be inflated until the outer cylinder of the shock rises high enough to fully expose the yellow inflation indicator sticker that you can see in its entirety on part # LC177223. There is not a listed max psi.

  • Should Cracked Air Bag for Trailair Air Ride 5th Wheel Pin Box be Replaced
    There isn't really a life expectancy rating for the air bag # LC432404 in your Trailair Air Ride 5th Wheel Pin Box simply because there are too many factors that go in to determining this (how often the trailer is used/not used, how much air is in the bag, climate, how exposed it is to the sun, etc...). With that said, from the picture you sent in I'd definitely go ahead and switch that out because yours looks really worn and 5 years service really isn't too bad. One tip I do have though...

    The Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs # LC369535 will have an air bag pressure range between 20 and 120 psi. Lippert techs say that sticker is there to assist but is not always accurate due to the fact it is a sticker that can be slightly misplaced. If your air bag is within the 70-100 psi range then they said not to worry about the sticker. It is a reference point and not a perfect guide. I recommend using a pressure gauge to confirm the 70-100 psi as...
