Ask the Experts about this Lippert Components Fifth Wheel King Pin

  • Replacement Air Ride or Sidewinder Pin Box for Lippert 1621
    The # LC328492 Trail Air Flex Air Air Ride Pin Box you mentioned is not an extended pin box. When installed, the center king pin to first row of bolt holes in the turret would be right at 17-3/4 inches, as you can see in the provided diagram. I've also shown the bolt hole spacing so you can compare it to your existing pin box. If you're looking for some extension to provide additional distance between the front of the trailer loft and the rear of the truck cab, you'd want to use a Sidewinder...

  • Easy Way to Tell Difference Between Lippert 1621 and 1716 Pin Boxes
    Easiest way it to measure vertically between the mounting holes of the pin box. If they are 2 inches apart up and down then you have a 1621. If that distance is instead 2-1/2 inches then you have a 1716. The part # LC1191191 that you referenced is for a 1621 pin box. For a 1716 instead you would need the part # LC1324791 for a similar style replacement.

  • Can 5th Wheel Trailer Pin Box Bolts be Installed from the Inside with the Nuts on the Outside
    I suppose you could run the bolts from the inside out when installing a pin box such as # LC1191191. You will have some of the bolt sticking out further than if it were just the head of the bolt but other than that provided everything was properly tightened I don't see a problem with it.

  • 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...

  • How Much Does a Lippert 1621 Pin Box Weigh
    Lippert 1621 5th Wheel Pin Box - 15,500 lbs Item # LC1191191 weighs approximately 100 pounds including the wings the pin box bolts to. Lippert 1621 5th Wheel Pin Box - 21,000 lbs Item # LC1387882 weighs approximately 115 pounds including the wings the pin box bolts to. The 20K Reese Goose Box # RP94720 that fits in place of the Lippert 1621 pin box weighs 170 pounds and the 16K version # RP94716 is approximately 159 pounds.

  • How to Adjust the Height of a 5th Wheel Trailer Pin Box
    When adjusting the height of a pin box such as # LC1191191 it is important to support the pin box when removing the bolts. I recommend 2 or 3 buddies to give you a hand and make sure no one is beneath the pin box while raising or lowering it. With the pin box supported unbolt it, raise or lower it as needed, and then put the bolts back in and tighten them down. According to Lippert use the following torque specs: Torque 1/2” bolts a minimum of 110 ft-lb. Torque 5/8” bolts a minimum...

  • Replacement Pin Box that Offers More Clearance than a Lippert 1621 Pin Box
    We have just want you need to get more clearance between the cab of your 2015 Ram 2500 and 2015 Cougar 5th wheel trailer. If your trailer and Lippert 1621 pin box are rated under 16,000 pounds gross trailer weight then you can use Sidewinder pin box # RP61420. If it is rated over 16K but less than 19K then you can use # RP61421. The Sidewinders do not allow the trailer to pivot at the hitch. Instead they lock out at the hitch and move the pivot point back 22 inches so the trailer rotates...

  • What Is Weight Difference Between Lippert 1621 Pin Box And Trailair Flex Air Pin Box
    I called my contact at Lippert and asked about the weight of the Lippert 1621 pin box, part # LC1191191 versus the Flex Air 18,000 pin box, part # LC328492. The # LC1191191 weighs 98-lbs. The # LC328492 pin box weighs 232-lbs, so it weighs more than twice as much as the # LC1191191

  • What is the Difference Between the Standard and Air-Ride 5th Wheel King Pin
    The stock Lippert 1621 pin box and air-ride pin boxes have some differences. For example, the Lippert 1621 5th wheel pin box # LC1191191 is a direct replacement for a worn out pin box. Whereas the Fifth Gear 5th wheel air ride coupler # 5AB-E1621-16K will have cushioned shocks with an adjustable air spring and shock absorber. Therefore, reducing longitudinal shock or chucking by nearly 60 percent and decreasing vertical shock by 44 percent. I included a video review about the Fifth...

  • Ideal Clearance Between Truck Bed Rails and 5th Wheel Trailer Overhang
    Ideally you will have at least 5 to 6 inches of clearances between the top of the truck bed rails and the 5th wheel trailer overhang. I attached a helpful image to assist. There are a few things you can do if you're having trouble maintaining this clearance with your setup, such as adjusting the 5th wheel hitch height, using a different set of mounting holes on the trailer's pin box, or if all else fails raising the height of the trailer itself. If you can tell me a bit more about...

  • Does Reese Goose Box Move Trailer Closer to Truck
    A Reese Goose Box is not going to move your trailer closer to your Dodge Ram 2500. For example, as you can see by the accompanying photos the Reese Goose Box # RP94720 measures about 18-1/2 inches from the first bolt holes to the center where the ball attaches while the pin box it replaces, the Lippert 1621 # LC1191191 pin box it replaces measures a very similar 17-3/4 inches from the first bolt holes to the center of the king pin. To determine what the correct Reese Goose Box is for...

Please don't pay any attention to the note on the product page, "NOT CONFIRMED TO FIT 2004 Keystone Cougar Fifth Wheel".

  • Is Lippert 1621 Pin Box # LC1191191 Compatible with Pop Up RV5 King Pin Extension Adapter
    I can see the appeal of the RV5 king pin extension and I have not heard of any issues with it fitting a Lippert 1621 pin box. But I can tell you that the use of an adapter will more than likely void the warranty on the trailer. Also, since the distance from where the trailer couples to the hitch back to where the pin box mounts to the trailer will increase using this adapter it will put significantly more stress on the trailer frame. A better option is a Sidewinder replacement pin box,...

  • Will Lippert 1621 5th Wheel Pin Box Fit a 2016 Crossroads Reserve 27BH
    If your 2016 Crossroads Reserve 27BH has a 1621 pin box then yes, the Lippert 1621 5th Wheel Pin Box # LC1191191 will fit your application. If you have a different number (which can be found on the pin box sticker) or are unsure just let me know and I can help you find out what you have. Unfortunately when I have spoken with trailer manufacturers in the past they required detailed information about the trailer that only the owner has access to for them to confirm the pin box number.

  • Picking Out Lube Plate for Fifth Wheel Hitch Connected to Lippert 1621 Pin Box
    Typically the size lube plate to use is recommended by the fifth wheel hitch manufacturer. Normally you want to match the size of the lube plate with about the same diameter of the hitch head's top plate. The 10 inch size is definitely the most common like the # RP83002 but for some of the Curt hitches they recommend a 12 inch plate like the part # C16722. Let me know what hitch you have and I'll see what is recommended.

  • 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.

  • Will Upgrading 1621 Pin Box on 2017 Crusader Lite Allow 5th Wheel to Sit Level
    I reached out to my contact at Lippert who said that the correct pin box for your 2017 Crusader Lite is the 1621 # LC1191191. Although we do have replacement pin boxes and pin box upgrades, like the 5th Airborne Premium # 5AB-E1621-16K, I have a few things for you to check first. There are some adjustment holes on the wings of the pin box so you can try adjusting the height of the pin box. Most 5th wheel hitches have height adjustment options as well so that is something else you can...

  • Why is the Locking Plate # DM6025 Required for a MOR/ryde Pin Box When Using the Autoslide Hijacker
    Most pin boxes, like the common Lippert 1621 # LC1191191, have a solid connection to the king pin and can be secured to the Demco Hijacker Autoslide # DM8550034 via the built-in brackets. Since the MOR/ryde pin boxes have a unique connection to the king pin the Locking Plate # DM6025 is needed so that the pin box can remain secure. This locking plate has a wedge on it so if you were to tow your trailer with a 5th wheel hitch that doesn't automatically slide (and has the same funnel size...

  • How to Measure Pin Box Height for Choosing 5th Wheel Hitch on a 2013 Ford F-350
    That is an excellent question and I agree that sometimes terms like this can be a bit confusing. Even though the king pin does connect to the jaws of the 5th wheel hitch, when you take your measurements it is much easier to go from the ground to the top of the 5th wheel hitch and then from the ground to the plate of the pin box (where the king pin connects to the box) which rests on the top of the 5th wheel hitch. I reached out to Heartland RV to see if they knew what the pin box...

  • Will Trailair Rota-Flex Keep Fifth Wheel at Same Height When Replacing Lippert 1621 Pin Box
    I reached out to the manufacturer and got the specs for both the Lippert 1621 5th Wheel Pin Box # LC1191191 and the Trailair Rota-Flex # LC328330 which it is designed to replace. These pin boxes have very similar dimensions, though the the Rota-Flex is about an inch lower overall. This small difference should allow you to keep your trailer level, though you may need to slightly adjust the height of your truck's fifth wheel hitch.

Make sure to back up your truck under the trailer and measure from the top of the ball in the truck bed to the base of the pin box on the trailer as well.

If the dimensions of your pin box match those on the LC1191191 then the pin box cover # LC301458 should work great for you.

  • Can B&W Companion 5th Wheel Hitch Be Used with Reese Sidewinder
    The B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter part # BWRVK3500 is not compatible with rotating pin boxes even if you lock out the turret. The reason for this has to do with the the excess torque on the single connection point and its inability to withstand this. Therefore, your best option would be to remove the rotating pin box and replace it with a standard pin box. For this, we have the Lippert 1621 5th Wheel Pin Box part # LC1191191 which is rated for 15,500 lbs and...
