Video Transcript for Lippert 1621HD 5th Wheel Pin Box Review

Randy: Hey guys, Randy here at etrailer.com. Today, we're taking a look at the fifth-wheel replacement pin boxes from Lippert. They have several models available like the 1116, the 1716. This one's the 1621 and they have these in different weight ratings depending on what your campers weight is. And basically you're going to get a brand new pin box, which the important part there is the new King pin. We're going to get a new perfectly round non ream King pin.

And you will also get the actual mounting bracket for it.You can see this is the portion that connects up here underneath to the actual RV. And then we use these holes on the side to attach our pin box to. Now, this is going to come in really handy of course, if you've had some kind of damage, whether there's some kind of impact, an accident may be and it's twisted or shifted this, that'd be ideal where you're going to be using this component or if you're just building a new fifth-wheel. That is steel trailer, you want to add a fifth-wheel bracket to the bottom and put your King pin on it. That's going to be included as well as the hardware.

So this particular pin box uses five bolts on each side.We've got the bolts, the washers, the lock washers, and the nuts for that application. So you don't have to worry about reusing old rusted or damaged hardware. When working with customers they often ask, "How do I know which pin box I need or which one's going to be the right one for my camper" And basically on all of your pin boxes, you're going to have a stamped series of letters and numbers in the side of it. That's what you want to use to reference which one's going to be the right one for your application.Now, of course, this is a King pin that we use to connect to the trailer to a truck. So it's extremely heavy duty, has a nice black powder coat finish on it, helps to withstand any of the elements out there.

This is going to be a direct replacement. So this is the exact thing that generally is going to come on your 1621 equipped camper or your 1116. The one thing to keep in mind is oftentimes, people will upgrade this. So this is a standard, just a steel link, right Some of them have airbags on them.So if the ride quality that you've been experiencing isn't what you want or if you get some of that weight coming down in the back of the truck and you can kind of feel it through the truck, adding a pin box or upgrading instead of getting this one, maybe get one that has the air ride like the 5th Airborne. That'll give you an air cushion in there or the GEN-Y, the really nice fifth-wheel King pin that'll connect to a fifth-wheel and has like a torsion axle built into it.

Both of those are really good options as well. So, if you've been pleased with the quality you got and you don't have any complaints, I think this is an excellent replacement. So overall guys, this gets us right back to where we started from the factory, which is an excellent thing. Nice heavy duty steel connection point, perfectly round King pin.So there's no chucking or bucking that we'll have to deal with if we didn't already it in the past. And I would say, if you've been satisfied with the ride quality between your camper and truck, this is definitely the way to go. If you're looking for a little bit of an upgrade, check out one of the air-ride options like the 5th Airborne or the Torsion-Flex style from GEN-Y. They can offer you a real nice upgrade and install just the same way this one would. So definitely something to consider.

I was greatly surprised to find that the replacement hitch had been re-engineered. I was expecting to add reinforcement to the hitch before mounting it to the trailer. I had previously bent two hitches when I had to jump on the brakes when cut off by idiots on the highway. From what I seen in this hitch I believe it will now do what I need it to do!! Thank You



by:

The order was good but was delivered to 3601 Highway 4 should have been delivered to 3601 CR 424. Shipping label had correct address. Please contact shipper and tell them to READ shipping label!



by:

Exact replacement for the damaged original, easy install, good price and quick shipping!



by:

Teresa J, was very helpful she did a great job in making sure I received the correct hitch, shipping was supper fast. The price was the best that I found on the internet. The hitch is very sturdy and heavy duty thanks for the great help.

Well, unfortunately half inch off - my bad. So, had to get someone to fix it. Once it was on, it worked great.

Choosing the correct replacement pin box can sometimes be tricky. I have attached a helpful article that explains how to find the correct replacement pin box depending on what you have on your trailer.

  • Recommended Adjustments To Get Additional Clearance For Fifth Wheel Trailer From Truck Bed Siderails
    Normally, the fifth wheel hitch in the bed of the truck has a height adjustment, and may be all you need. You can also adjust the height of the pin box to gain more clearance. Ideally you want about 6-inches from the top of the truck side rails to the bottom of the trailer loft.

  • Weight of Lippert Pin Boxes LC1191151 and LC1387882
    I spoke to my contact at Lippert and the 15k Pin Box part # LC1191151 that you referenced weighs 104 lbs and the 21k Pin Box # LC1387882 weighs 115 lbs. The 21k would be the stronger one.

  • Solution for Trailer with Roto Flex Pin Box that Needs to be Taller for Bed Rail Clearance
    The Roto Flex style of pin box that you have would be replaceable with other styles of pin box but without knowing what exact model you have it's hard for me to say what would fit. Also worth noting is that the replacements won't have significant dimension differences so you'd most likely end up with the same issue or very similar. So instead you might need a taller fifth wheel hitch to give you the additional clearance so that your trailer stops hitting the bed rails. For example the...

  • Replacement of King Pin Box
    The Lippert 1716 5th Wheel Pin Box, # LC1324791 is is 12.5" in width. The Lippert 1621, # LC1387883 and the Lippert 1621HD 5th Wheel Pin Box, # LC1191151 are both 12" in width. The easiest way to replace your pin box is to find the pin box's manufacturer name along with its specific pin box number. These are both typically located on a sticker on the pin box or on the king pin itself. This pin box number will usually be 3-4 numbers long and can have letters attached to it. Some very common...

Since you mentioned you have the Venture CJ13517 pin box, this is not going to work for you, however I do have another option. Check out the: -Trailair Air Ride 5th Wheel King Pin # UF35-946219 instead. This pin box will work as a replacement for Steelco/Davis PB01, Venture CJ13515, CJ13517 and Short pin boxes. .

  • How to Increase the Clearance Between the Truck Bed Rails and the Bottom of a 5th Wheel Trailer
    I recommend that you do not remove or change the setup of the pn box on your 2006 Grand Junction 5th Wheel Trailer. There may be a reason that the Mor/Ryde pin box needs 10 bolts to mount to the trailer. Removing one bolt may weaken the mount and could cause catastrophic damage to your trailer and vehicle if there is a failure. There is one thing you can try before altering or replacing the king pin on your 2006 Grand Junction 5th wheel trailer. The Curt Q24, # C16545-16025 that you purchased,...

  • Does the Andersen Ultimate Connection 5th Wheel Trailer Hitch Adapter Work wtih Lippert 1621 Pinbox
    The Andersen Ultimate Connection, part # AM3200, works with any fixed fifth wheel pinbox. It doesn't work with rotating pin boxes. So as long as your Lippert 1621 is a fixed pin box, like parts # LC1191191, # LC1191151 and # LC1387882 it'll work just fine for you.

  • How to Reduce Chucking and Jarring While Towing a 5th Wheel Trailer
    Chucking and jarring while towing a 5th wheel trailer (or any trailer for that matter) is unavoidable because the trailer itself is not one piece with your vehicle. When your truck starts to move forward from a stop your trailer is still sitting static and so there will be a slight jolt; the same thing happens when you slow down. Since the front end of your trailer is connected to your truck, when your truck starts to slow down your trailer is still moving forward so it will give you a...

  • Can Trailair Flex Air # LC328492 Replace Lippert 1621HD Pin Box on a 2017 Jayco Seismic Wave 355W
    You are on the right track of choosing an upgrade for the Lippert pin box on your 2017 Jayco Seismic Wave 355W. Since the pin box is a 1621HD instead of a regular 1621 you need to go with a different pin box as the Curt Flex Air # LC328492 is only compatible as a 1621 replacement. If you like the Curt line then you can use the Curt Air Ride # LC158778. This is rated for 21,000 lbs and the only difference between this and the Flex Air is that the Flex Air has a pivoting head which further...

  • Replacement Pin Box Needed to Tow a 2018 Reflection 337RLS with a PullRite SuperLite
    I spoke with someone over at PullRite who said that they have heard from customers that a standard pin box that doesn't have any cushion actually tows better with the PullRite SuperLite 4P 20,000lb hitch that you are using. Since the hitch comes with an adapter for the king pin all that we need to know is the model number of your current pin box. This can actually be found on the pin box itself. There should be a sticker that has a series of numbers on it. It should reflect one of the...

  • Gaining Clearance Towing Fifth Wheel Trailer with 1116 Lippert Kingpin and 2013 Ford F-250 Short Bed
    The Lippert 1621 Fifth Wheel Pin Box # LC1191151 is considered a long pin box however the bolt holes are not going to line up the same as your Lippert 1116. The 1621 that we carry is a direct replacement to be used on trailers that were originally manufactured with a 1621. It's not intended to be used to add length on a trailer that has a shorter pin box. One option to gain clearance is to use a sliding hitch, like the Reese # RP30928 with rail adapter # RP30156.

If your 5th Wheel has a GVWR of 11,501 to 14,000 lbs then I recommend the MORryde Cushioned 5th Wheel Pin Box - Fabex 500 - 15,000 lbs Item # MR76XR. Both of these pin boxes have a the same bolt pattern as your Fabex 500 but come with different weight ratings to match your 5th Wheel. I've attached a video...

  • Would Changing Length of Shackle Straps Affect Overall Height of Trailer
    While changing the length of shackle straps isn't an ideal way to change the ride height of a trailer. If you were to shorten the shackle straps the trailer would sit slightly taller. This isn't ideal as the leaf spring wouldn't sit level if you made a drastic change. Over under kits are better for changing ride height as you get a more substantial lift and the suspension stays level. The diameter of your trailer axle will determine the size of the parts that you will need to order. If...

So you can use these to adjust the front of the camper and get your camper to a more level height with your truck. Raising the truck would also affect this.

  • Can the Convert-A-Ball Gooseneck Adapter Be Used With A cushioned 5th Wheel Pin Box?
    I have a couple of solutions – just not with the Convert-A-Ball. The Convert-A-Ball # CAB-C5G gooseneck adapter cannot be used with most cushioned or air ride pin boxes, or rotating pin boxes.. The additional flex of two cushioning devices creates leveraged angles that can break both pin box parts and truck parts.

If you are wanting to replace it directly then we do have a few options like the 18K part # LC1191151. For a pin box upgrade I highly recommend the 5th Airborne Premium Fifth Wheel Air Ride Coupler. This comes in 16K # 5AB-E1621-16K and 21K # 5AB-E1621-610 options and is one of the best pin box upgrades on the market. It has an air bag and shock that are used...
