I researched the product thoroughly and the price and free shipping were above the competition. The Pinbox was exactly as ordered, although the shipping container was in pieces when it arrived. The customer service agents were at the top of their game and pin point professional. 366661

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 254921

  • Options to Raise the Overall Height of a 5th Wheel or Travel Trailer
    Installation of a replacement pin box like the Lippert 1621 5th Wheel Pin Box - 18,000 lbs # LC1191151 does not raise the overall height of a 5th wheel trailer, but it may give more adjustability to the height of the king pin. I've attached an image of the dimensions of this pin box as well as the adjustability based on hole spacing 2 inches on center vertically. I've attached a link to all of the pin boxes compatible with the 1621 for your convenience. To give you additional trailer...

  • 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 Trailair Flex Air # LC328492 is only compatible as a 1621 replacement. If you like the Trailair line then you can use the Trailair 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...

  • 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...

  • 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 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...

  • 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 # RP30083 with rail adapter # RP30156. Or if you already...

  • 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.

  • Recommended Sliding Fifth Wheel Hitch For 2016 Ford F-250 With Short Bed
    There are a couple ways you can go for a towing setup. If you want full access of your 2016 F-250 truck bed when you are not towing I recommend an underbed rail system for your fifth wheel hitch like the Demco, part # DM8551000. I then recommend a sliding hitch like part # DM8550022. This hitch has 14-inches of front to back travel so you can make sharper turns. The great thing about this hitch is that you do not have to exit the truck when executing turns because this hitch automatically...

  • Adjusting Your Trailer So That the Pin Box Sits More Level on a Jayco Eagle 5th Wheel Trailer
    If you can safely adjust the height of your Lippert 1621 pin box then that would be the ideal thing to do. I do have a few more options to help level out your Jayco Eagle with your 2017 Ford F-250 Super Duty. If your Jayco Eagle uses leaf springs, Dexter has 2 different over-under conversion kits which will move the axle from over your leaf springs to under your leaf springs. The Conversion Kit # K71-384-00 fits a 2-3/8 inch axle while the Conversion Kit # K71-385-00 fits 3 inch...

  • 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.

  • 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...

  • Replacement Pin Box Needed for a Lippert 1621 Pin Box
    I reached out to my contact at Lippert who said that the serial number you gave me means you have one of the common 1621 pin boxes. 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...

  • 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...

  • 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....
