Video Transcript for Lippert 1621HD 5th Wheel Pin Box Installation - 2010 Starcraft Homestead Fifth Wheel

Hey guys, Randy here at etrailer.com. Today, we've gotten a 2010 Starcraft Homestead, and we're going to be switching out the pin box on it. This is a new pin box. We'll show you the installation process in a minute. But essentially this is going to be from Lippert components. This is the direct replacement.

This one uses a 1621 pin box. Now, Lippert has this in a standard. They've got it in an HD and then a SHD which would be super heavy duty. Now on the standard duty model, it's going to have a 15,500 pound capacity. The heavy duty which we've put on here is the 18,000 pound, and the super heavy duty is going to go to 21,000 pounds.Overall, this is going to be an exact replacement for what you've got on there now.

Just restores everything, gets our king pin back to where it's round in case we've had any damage there. And it will include the mounting brackets that actually attach up to your fifth wheel. So maybe you've backed into it and you've bent it or damaged it one way or another and you need a new solid bracket to mount, that's going to come with it as well. Or if maybe you're rebuilding a trailer, whatever your case might be. But it's nice heavy duty, steel construction, has that nice black powder coat finish on it.

And the installation process isn't all that difficult. It's a little bit off way that it'll pull down on the front more so than in the back. But two guys can very easily, once you remove your bolts, lower this down and out, get your new one up and in, and it comes with the new hardware to attach it, so you're not going to be reusing the old 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" Basically, on all your pin boxes, you're going to have a stamp series of letters and numbers on 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, it's a king pin that we use connect a 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 Eclipse camper or your 1116.The one thing to keep in mind is, oftentimes people will upgrade these. 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 the back of the truck and you can 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, a really nice 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. But if you've been pleased with the quality you've had and you don't have any complaints, I think this is an excellent replacement.Now, the replacement process isn't that involved, you just got to remove some bolts, get the old one out, new and in and put some new bolts in. These can be a little bit heavy, so I recommend having two guys when you go to actually pull it out and place it back in. Let's take a look at that process now. Of course, we need to get our old pin box out of the way here. You want to inspect it first. You can see here, we've got our breakaway switch that's attached, so we're going to be removing that self-tapper to get that out. Check your wiring, to make sure that it doesn't run through one of the holes on the pin box or something. And then also check your 7-pole plug. This one runs up in end, so we're in really good shape there, nothing's attached to the pin box. But sometimes the 7-pole will be ran to a junction box on the pin box, then it goes back from there. So just really inspect it properly, make sure you're not going to be doing any damage to the wiring. And then we'll take out the main bolts here and get our old one out of the way.We'll start on our larger bolts here. It's going to be a 15/16, just keep that in mind. (silence). You can see as I'm removing these, I'm leaving some of them in here. They don't have nuts or lock washers on them, but once I get this last one loosened up, I don't want the pin box to fall, so that's just there as a fail safe, just to hold it for us. Once we get an extra set of hands, we can pull those out and take this one out.Now with the help of an extra set of hands, we're just going to start wiggling this guy out of there. You can see, fairly easy for one guy to hold, a little bit heavy, but you'll be able to manage. Set it aside and get our new one in place. Now, we've got our new one coming in. With doing this, we're also going to use the new hardware. I know we had good hardware that was there before, but I like replacing it when we get the opportunity. You can see it takes a little bit of force to get them in there sometimes.Now that we've got all of our bolts and hardware started, remember we're going to have the bolt with a flat washer on the outside. On the inside, there's a lock washer and a nut. We're going to get all these snugged down, then we can torque them down appropriately. (silence). Then on the side on our breakaway switch location, we use a self-tapper to get that in place.Well, guys, I hope that was helpful. Shows you how to get the pin box out and how to get the new pin box in and some of the details on it. Again, that's going to complete our look at the 2010 Homestead by Starcraft pin box replacement.

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!

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

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:

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.




by:

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


Comments
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.

Review from a similar Standard Pin Box in Fifth Wheel King Pin


For those of you who, like me, may have purchased a truck with the under the bed rail system for your fifth wheel you know the positioning of the rail system is set in front of the rear axle instead of directly above the axle making the distance between the cab and trailer that much closer. This can cause a problem hooking up with your tail gate in the down position if you have a medium length pin box on your trailer. etrailer has a great chart online to help you determine what kind of pin box you have and if there is another one manufactured that will fit in the same place. This longer pin box for me was a great economical, safe solution. The Lippert 1716 long box is a direct replacement for the Lippert 1116 medium box, but is seven inches longer giving me the needed distance to hook up.

  • 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.

  • 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...

    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...

    I recommend that you do not remove or change the setup of the pn box on your 2006 Grand Junction 5th Wheel Trailer.

  • 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.

    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 pin box is a 1621HD instead of a regular 1621 you need to go with a different pin box as the Trailair Flex Air # LC328492 is only compatible as a 1621 replacement.

  • 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...
